ABSTRACT: This thesis was completed in order to assess and document the environmental effects that are the result of elemental phosphorus production in Pinellas County Florida. The study utilized a collection of information resources that included: personal interviews, technical references, historical documents, legal documents and field observations. By utilizing five different sources of information a broad understanding of the problem was developed. Pinellas County and Tarpon Springs officials were interested in creating a more diversified economy in the years following World War-II. The Victor Chemical Works Company responded to the interest in economic diversity by proposing to build an elemental phosphorus production facility in the area of greater Tarpon Springs, Florida. The elemental phosphorus production facility was completed and began operation in November of 1947.Three months after the facility commenced production local residents noticed damage to trees and painted surfaces on private properties. Seven months following commencement of elemental phosphorus production local residents filed suit against the Victor Chemical Works Company due to deleterious gassesand dust that appeared to be damaging to biologic health. The elemental phosphorus production facility operated from 1947 to 1981. The 34-year operational period exposed workers, residents and biologic communities to extended periods of elevated sulfur dioxide, phosphorus pentoxide gas, phosphine gas, fluorine, lead, radium-226 and asbestos. Utilizing personal interviews, technical document review, legal document review and field observations the thesis provided an amalgamation of diverse information upon which the conclusions were based.The research concludes that the production of elemental phosphorus exposed all physical and cultural environments of northwest Pinellas County to many complex adverse environmental impacts that continue to persist in 2007, approximately 26-years following the suspension of production.

vi The Historical Production of Elemental P hosphorus in Pinellas County, Florida: An Environmental Assessment Stephen D. Robinson ABSTRACT This thesis was completed in order to asse ss and document the environmental effects that are the result of elemental phosphorus produc tion in Pinellas County Florida. The study utilized a collection of inform ation resources that included: personal interviews, technical references, historical documents, legal docu ments and field observations. By utilizing five different sources of information a broad understanding of the problem was developed. Pinellas County and Tarpon Springs official s were interested in creating a more diversified economy in the years following World War-II. The Victor Chemical Works Company responded to the interest in ec onomic diversity by pr oposing to build an elemental phosphorus production facility in th e area of greater Tar pon Springs, Florida. The elemental phosphorus production facility was completed and began operation in November of 1947. Three months after the facility commenced production local residents noticed damage to trees and pain ted surfaces on private properties. Seven months following commencement of elemen tal phosphorus producti on local residents filed suit against the Victor Chemical Works Company due to deleterious gasses
vii and dust that appeared to be damaging to biologic health. The elemental phosphorus production facility operated from 1947 to 1981. The 34-year operational period exposed worker s, residents and biologic communities to extended periods of elevated sulfur dioxi de, phosphorus pentoxide gas, phosphine gas, fluorine, lead, radium-226 and asbestos. Utilizing personal interviews, technical document review, legal document review and field observations the th esis provided an amalgamation of diverse information upon which the conclusions were based. The re search concludes that the production of elemental phosphorus exposed all physical and cultural environments of northwest Pinellas County to many complex adverse enviro nmental impacts that continue to persist in 2007, approximately 26-years following the suspension of production.
1 Chapter One Introduction The purpose of this thesis is to identify and assess the environmental impacts that have resulted from the industrial produc tion of elemental phosphorus in northwest Pinellas County, Florida. The research pr oject utilizes personal interviews and the investigation of Federal deposito ry documents, pertinent scien tific studies and reports to analyze the adverse environmental impact s associated with elemental phosphorus production in Pinellas County. The environmen tal historical component of the study will track the history of the envi ronmental impacts imparted by the production of elemental phosphorous in Pinellas County from (1947 to 1981) and the post production effects from (1981-2007). To understand the extended enviro nmental history of the study area it is necessary to step back in time to gain a more fully de veloped perspective of the dynamics that helped to create the adverse environmenta l condition(s) that continue to exist today. In addition, the physical geogr aphy of northwest Pinellas Co unty has imparted, important environmental components that imposes subtle dynamics that have helped exacerbate the adverse effects elemental phosphorus production to the adjacent communities of Pinellas County. The project will also at tempt to address the elements of public safety related to the production of elemental phosphorus Pinellas Count y, Florida. The incr emental shifts in
2 the accepted industrial culture frequently accept and then later abandon industrial practices that could be detrimental to the safety of the public at large. Public safety has often been knowingly and unknowingly sacrific ed by heavy industrial procedures. The disregard for public safety has frequently been a process of tr ial and error usually resulting in public safety improvements follo wing an extended period of environmental hazards that were imposed on the public a nd the various ecological communities in the affected area. Production of elemental phosphorus in Pine llas County created large airborne emissions of synthetic toxic gasses and dusts The airborne synt hetic toxic emissions were the result of melting raw phosphate rock from which elemental phosphorus, iron and fluorine could be collected and mark eted. The local human and biologic communities were exposed to the pervasive cl ouds and gasses twenty four hours a day. The airborne emissions were dispersed by the micro-meteorology phenomenon that tended to magnify the adverse environmenta l impacts in a local context. The industrial scale production of elemen tal phosphorus within northwest Pinellas County created numerous synergistic synthe tic toxic (xenobiotic) compounds that are currently known to be hazardous to humans and various other soil and water biotic organisms The industrial production of elemen tal phosphorus also spawned a plethora of synergistic toxic by-products that have only recently become known to the public in the surrounding community. The industria l production of elemental phosphorus also created significant damage to the commerc ial agricultural flora community. The commercial livestock community in the study area was decimate d as a result of the bioaccumulation of synthetic toxins that were dispersed over the pasture lands. Private
3 properties in the study area were damaged from the caustic dust and gas clouds that emanated from the Victor Chemical Works and Stauffer Chemical Corporation production facility. Pinellas County re sidents became aware of the adverse environmental change approximately in Janua ry of 1948 approximately two months after production of elemental phosphorus commenced. In the summer of 1981 production of elemental phosphorus in Pinellas County came to an end and almost immediately the adverse air quality returned to safe ambient levels. However, the long term adverse environmental effects of elemental phosphorus production had not dissipated as quickly as the gas and dust clouds had. Pinellas Count y residents, properties and environmental resources were been damaged by persistent ad verse toxic agents that did not dissipate with the large gaseous emissions created fr om 1947-1981. It is the coupled combination of residual and ephemeral environmental dama ge created by toxic ag ents that continues to manifest environmental degrada tion in Pinellas County, Florida. Pinellas County and Federal environmenta l officials continue to toil with a politically astute public who are deeply c oncerned with their long-term health and welfare. The citizens of nor thwest Pinellas County are c oncerned that their physical health and economic wealth was and continues to be sacrificed in order to cater to the profitability of the powerful chemical industry (Ryburn, 2006).
4 Chapter 2 Review of Literature This review of existing research amalgamate s this project into the larger discourse of existing academic research. It specifi cally focuses on the adverse environmental aspects of elemental phosphor us residual contamination. The Army Corps of Engineers (Racine 1992) sanctioned a five-year study regarding the fate of elemental phosphorus called, Persistence of White Phosphorus in Sediment The research was conducted at Eagle River Flats, Alas ka at the location of an abandoned United States military artillery testing f acility that had been used to test elemental phosphorus munitions. It was dete rmined that white phosphorus indefinitely persisted in saturated sediments. Saturated soils are soils that have no dissolved oxygen components in the soil profile. It was furt her determined that elemental phosphorus was the cause of waterfowl deaths at Eagle River Flats. It was the more obvious loss of waterfowl that stimulated discussions what could be done to mitigate the adverse environmental effects of elemental p hosphorus contaminated sediments. During laboratory experiments, it has been determined that the sediment moisture content was the more important of the tw o factors tested in the context of the environmental persistence of elemental phospho rus in the Eagle River Flats sediments. As a solid parcel in reduced soils, elementa l phosphorus is highly pers istent and can exist unchanged for up to 10,000 years. However, in soils with adequate free pore space, it is
5 possible for elemental phosphorus to convert to a vapor phase and diffuse or be oxidized as orthophosphate. Diffusion of elemental phosp horus in soil has been shown to continue as long as there is sufficien t free pore space to support di ffusion processes associated with this synthetic compound (Baver, 1956). The research project at Eagle River Flat s, Alaska has revealed that elemental phosphorus has the potential to contaminate water and soil when it is he ld in a persistent reducing/anoxic environment. The research at Eagle River Flats is very relevant to Pinellas County because the Victor/Stauffe r Super-Fund Site is contaminated with elemental phosphorus that has been buried in anoxic conditions si nce at least 1981. The study conducted at Eagle River Flats, Alaska asked the question; what is the ultimate environmental fate of elemental phosphorus in the soil? (Collins, and others 1995). The Victor/Stauffer Super-Fund Site might eventual ly provide the answer to this question within a sub-tropical context. Pinellas County soils do not freeze and this phenomenon would seem to enhance the dispersion of phosphine and orthophosphate gasses. Clarkson (1991) determined that under anoxic conditions elemental phosphorus is an extremely toxic compound. However, wh en elemental phosphorus is held under aerobic conditions it has the poten tial to rapidly degrade to non-toxic phosphates. Under aerobic conditions elemental phosph orus usually dissipates fro m soil sediments as a more benign phosphine or orthophosphate gas. Befo re this specific study was completed in 1995 it had been hypothesized that elementa l phosphorus was a benign non-persistent compound in the environment, including soils of all types (Collins, and others 1995).
6 This specific study clearly reveals that seasonal and permanently saturated hydric soil(s) and soils influenced by saline ground wa ter can inhibit the chemical degradation of (P4) or elemental phosphorus (Clarkson, 1991). In another relevant study, Garbage Wars : The Struggle for Environmental Justice in Chicago (Thornton, 2000) research focused on th e environmental ri sk the public was exposed to in Chicago, Illinois area garbage industry during the period from the 1800 to 2000. This specific research project closely parallels the thesis research within the context of public health risk and adverse envi ronmental impacts that are associated with industry in close proximity to human concen trations. Collectively, the Victor/Stauffer Chemical Corporations and the garbage indus try of Chicago have and to some degree continue to impose the greatest adverse envi ronmental impacts on the public who were or continue to be politically disenfranchised. The Victor/Stauffer Chemical Corporation processing plant site was strategically placed in an area of northwes t Pinellas County that had a pre-existing geo-political insular identity. Northwest Pinellas County in 1947 was located in an economically disenfranchised ge ographic realm with li ttle to no constituent political power base. During 1947 the citi zens of the northwest Pinellas County study area were aware that the economic conditi ons had weakened as the greater Tarpon Springs economy was declining. Thornton (2000), states that people of co lor, low income and the politically disenfranchised tend to carry the heaviest burden in the context of pollution and solid waste hazards. He argues that eventually the elite and affluent will face the issue of environmental contamination in their work places and neighborhoods. The elites will eventually face contamination in their ow n homes because the industrialized North
7 America is creating more waste each year and the dependence on synthetic compounds and their polluting products cr oss all socio-economic gradient s. ThorntonÂ’s conclusions also appear to hold true in Pinellas County as the lower income residents who had lower employment skills tended to accept the work opportunity at the Victor/Stauffer elemental phosphorus production facility. In a project similar to my proposed thesis research project, Markowitz and Rosner (2002) ( Deceit and Denial: The Deadly Po litics of Industrial Pollution ) attempt to reveal the conscious effort of the chemical industry in the United States to distort and conceal the publicÂ’s knowledge of hi ghly marketed chemical co mpounds and environmentally dangerous products. In particul ar, the research focuses on the proliferation of lead as a particularly insidious material that was co mmonly sold and delivered into millions of AmericanÂ’s homes and buildings as a life-improving product. The authors of this specific research work uncovered evidence and conducted numerous personal interviews with many of the significa nt individuals who were involved within the hidden recesses of i ndustrial product development and marketing. Certain elements of the chemical industry perceived that envir onmental pollution was a significant hazardous issue that had long been denied by many in the industry at their own peril. However, knowing this, the chem ical industry continue d to act on a united front, saying that it could be trusted to safeguard the public and the environmental as a whole (Markowitz and Rosner 2002). The Vi ctor/Stauffer Chemical Corporation SuperFund Site represents another tangible example of deceit and denial that has been imposed on, in this case the people of northwest Pinellas County. The production facility was initially operated at the accepted industrial st andard. However, as government codified
8 regulations tightened in the late 1970s it becam e very apparent that the corporate owner of the facility could not make the financial commitment to enhance public safety. This particular behavior ultimately evolved into industrial denial that left the citizens exposed to significant adverse envir onmental conditions over an extended period of time. The Love Canal region of the Niagara Rive r basin represents another comparable study area. Love Canal is the place name where the Hooker Chemical Company disposed of chemical by-products between 1942 and 1952. The Love Canal chemical disposal site has several repe ating similarities that are sh ared at the Stauffer Chemical production facility. Both areas are active EP A-Superfund sites, both sites are in close proximity to large population areas, and each of these ch emical facilities were being brought on-line when new and influential pow erful chemical industries were gaining a foothold in the American economy. Anothe r common connection bo th the Love Canal and the Stauffer Chemical production facility sh are is the fact that earthen burial was used as the means to dispose of unwan ted toxic by-product compounds. The Hooker Chemical Corporation and the Victor/Stauffe r Chemical Corporations both shared the need to dispose of the unmarketable by-produc ts that synthetic chem istry was creating in great quantities (United States En vironmental Protection Agency, 2002). There were no State or Fede ral sanctioned statutes for the disposal heavy industry by-products at this time. Governmental overs ight led to some disastrous consequences relative to corporate disposal techniques of toxic synthetic co mpounds. It is in this way, that the Hooker Chemical Company and the Victor/Stauffer Chemical Companies made disposal choices that continue to adversely affect the environment of the residents that
9 live or work near either of the subject EPA Super-Fund Sites (United States Environmental Protection Agency, 2002). Another contaminated site, the Shattuck Chemical Corporation constructed and operated a uranium and mineral processing plant in an area that in the 1920s was rural, but by the 1960s became prime real estate The uranium processing facility was gradually surrounded by very expensive wint er vacation homes within the rapidly suburbanizing foothills of the Rocky Mountains The site was assigned to the SuperFund Interim Properties list in October of 1981, and due to the extensive contamination uncovered near areas of human occupation, the site was included on the National Priorities list on September 8, 1983 (EPA Region-8 Report, 2004). The Shattuck Superfund site closely para llels the adverse environmental risks and exposure probabilities that took place and c ontinue to exist at the Victor/Stauffer Chemical Super-Fund site. The Victor/Stauffer facility also had an extended period of production that exposed operational workers, area residents and non-human organisms to dangerous inhalation, oral and dermal e xposure to elemental phosphorus, and the associated zenobiotic chemical byproducts that are coupled to high temperature elemental phosphorus production. It was only after the Stauffer Corporation production facility closed in 1981 that the full scope of elemen tal phosphorus hazards became known to the public at large.
10 Chapter Three Research Design and Methods Research Design Problem Statement This research project will provide a co mprehensive case study utilizing personal interviews, historic literature analysis and technical documents to assess the short term and long term adverse environmental impacts that were imposed on the public and other biologic communities as a direct result of elemental phosphate production in Pinellas County. The study will reveal the environmental issues that existed in 1947 and continue to persist more than 26 y ears after elemental phosphorus production was suspended in Pinellas County, Florida. Objectives As part of gathering data from hist orical sources, interviews and various government and technical reports, this thesis will specifically focus on: Analyzing the historic literature and the institutional knowledge of Pinellas County employees regarding the environmental risk factors for past employees associated with th e production of elemental phosphorus at the Stauffer/Victor facility.
11 Analyzing the historical literatur e and the institutional knowledge of Pinellas County employees regarding the environmental risk factors for the human residents in the study area associated with elemental phosphorus production. Analyzing the existing technical li terature and historic documents regarding the environmental risk factors of non-human organisms associated with elemental phosphorus production. Research Questions and Sub-Questions The over-arching research questi on for this research is: What are the adverse environmental impacts resulting from the production of elemental phosphorus in Pinellas County, Florida? In order to further assess the specific s of the adverse environmental impacts associated with the production of elemental phos phorus, this research will also utilize the following sub-questions: What are the adverse environmental impacts imposed on employees relative to air quality, wa ter quality and other forms of exposure in the study area? What are the adverse environmental impacts imposed on citizens relative to air quality, water quali ty and other forms of exposure in the study area? What are the adverse environmental impacts imposed on the non-human organisms relative to air quality, water quality and other forms of exposure in the study area?
12 Background In order to provide a broader context to the pervasive adverse environmental impacts of elemental phosphorus production th e next section will connect Pinellas County to a broader collection of knowledge on this topic. Pinellas County, Florida is not the exclusive geographic host site to the production of elemental phosphorus in the United States. The production of elementa l phosphorus has had adverse environmental impacts in other geographic locations of the United States. The cumulative adverse environmental effects of elemental phosphorus have also been documented in Montana, Alaska and Polk County, Florida. Pine llas County was expos ed to the adverse environmental effects of elemental phosphorus production prior to many other geographic areas within the United States and therefore the Pinellas County scenario is a prototype. The industrial incident that most parallel s the Pinellas County scenario occurred in Garrison, Montana when a rancher sold 54-acres of his land to the Rocky Mountain Phosphate Company (Fisher, Prival 1973). The Garrison, Montana community eagerly awaited the arrival of the new industrial employment oppor tunities. The Rocky Mountain Phosphate Company facility ha d come with the promise of jobs and much needed tax revenues for the industry-hungry region. However, in less than five years, it was noted that the indigenous Ponderosa Pines and Dougl as Firs were turning brown and necrotic, and that cattle on GarrisonÂ’s large ranches we re becoming incapacitated as the result of fluorides that were being emitted from the high temperature processing of phosphate ore. The cattle industry was virtually destroyed in less than five y ears. It took six years of frustrating campaigning to the various regul atory agencies before the residents of
13 Garrison succeeded in forcing the Rocky M ountain Phosphate Company to close in January 1970 (Fisher, Prival 1973). The production at the Victor Chemical Works elemental phosphorus processing facility (ownership changed to Victor/S tauffer in 1960) in Pinellas County, Florida commenced in November of 1947. As ear ly as January of 1948 the residents of northwest Pinellas County were noticing the necrosis of Slash Pine (Pinus elliottii ) and Longleaf Pine (Pinus palustris) trees and th e declining health of bovi ne livestock that had flourished prior to the commencement of pr oduction at the new Vict or Chemical Works facility. The industrial production of elem ental phosphorus in northwest Pinellas County continued unabated over a thirty four-y ear period until 1981 when production ended (Environmental Protection Agency, National Priorities List 1994). The period of 1947 to 1981 was a dynamic period when Pinellas County was attempting to transform from a poorly di versified agrarian and fishing economy and culture into the most densely populated metropolitan area in Florida. According to 1990 census data, approximately 14,000 people li ved within a one-mile radius of the Victor/Stauffer site north of the Anclot e River and approxim ately 4,700 people live within one mile south of the Anclote Rive r (Agency of Toxic S ubstances and Disease Registry 2003). Research Justification It is anticipated that this research will create a broad basis of geographic environmental knowledge that will be derived from the collection, documentation and interpretation of pertinent data. The speci fic research will be conducted in order to provide a comprehensive geographic context of knowledge, and to produce a basis of
14 documented knowledge that can be built upon as a foundation for further understanding heavy industrial production in th e region and to answer the st ated research questions. This research conveys an environmen tal history that developed within the confines of the insular northwe st section of Pinellas County. The early stages of this particular environmental history has not pr eviously been well documented, or formally presented in its totality to the public. The study will document and analyze the institutionalized recollections of the government employees and appointed officials who worked to safeguard the publicÂ’s welfar e. The study documents and analyzes institutional knowledge over a period of 60-year s. It was not until the late 1970s when issues regarding adverse environmental impacts were becoming politically prominent. Codified or enforceable environmental re gulations regarding elemental phosphorus production were essentially non-exist ent during the time period of 1947-1981. Pinellas County Commissioners attemp ted to diversify the Pinellas County economy following World War-II by courting h eavy industry. In retrospect, the uninformed decision of public o fficials was meant to serve th e constituents positively. This study shows that upon closer examina tion the public officialÂ’s good intentions opened the door to an extended period of time of environmental degradation in Pinellas County. Public officials in Pinellas County did not have the techni cal analyses tools available to them in 1947 to make prudent l ong-term decisions based on public safety and environmental sustainability. The absence of technical environmental knowledge is a reoccurring phenomenon in this study. A broad understanding of local and regional hydrology, meteorology, geology, pedolog y, edaphology, human toxicology and
15 industrial techniques would have given Pine llas County public officials the tools they needed to make a prudent environmental decisi on regarding the Victor/Stauffer facility in northwest Pinellas County The research therefore provides valuable insight into the establishment, proliferation and subsequent abandonment of the elemental phosphorus/phosphate industry in northwest Pinellas Count y. It is important that this research took place in that certain environmental contamination and degr adation in northwest Pinellas County were systematically linked to the Victor/Stauffer elemental phosphorus pr oduction facility. By combining personal interviews, hi storical research, review of existing public and private literature a new perspective was gained on th e adverse environmental impacts that have been imposed on Pinellas County as a result of 34-years of elemental phosphorus production. This study helps broaden the base of knowledge by adding additional information to the existing base of knowledge about the full adverse environmental implications of historic hea vy industry in Pinellas County. Methodology This section of the study provides the fram ework for the collection of the various datum collection methods. The study is de veloped within the framework of an environmental assessment case study. This proj ect will utilize a combination of archival records, personal interviews, participant obs ervation, field observati on and the review of public documents in order to reach its conclusions.
16 Interviews Historical and Contemporary Ethnography Interview Methodology Three personal interviews were comple ted with Pinellas County scientific and administrative staff members who were intima tely involved with th e monitoring of the Victor/Stauffer Chemical elemental phosphorus manufacturing facility while it was still in operation or during the post production EPA Super fund environmental coordination process. The interviews were conducted with the three offici als (Table 1) between August 9, 2006 and August 31, 2006 to account for the f act that several of the Pinellas County scientific staff members who hold valuable institutional knowledge were approaching retirement status. It was the intention of the intervie w schedule to allow as much institutional knowledge as possible to be secu red before it became unavailable in an open public context. Following the interviews, specifi c information relevant to this thesis were organized and fit into the framework of this study. (Table 1) Ms. Joyce Gibbs Pinellas County Real Estate, Coordinator Employment: 1974-present Mr. Peter Hessling Pinellas County Air Quality, Administrator Employment: 1976-present Mr. Charley Ryburn Pollution Recovery, Program Manager 1992-present This portion of the research attempts to assemble institutional knowledge, in both a long-term and contemporary context from individuals in close proximity to the environmental issues regarding the produc tion of elemental phosphorus in Pinellas
17 County, Florida. Based on specific management involvement in air quality, water quality and soil contamination in northwest Pine llas County: Ms. J oyce Gibbs, Mr. Peter Hessling and Mr. Charlie Ryburn were selected. Deliberate e fforts were made to secure the institutional knowledge of lo cal public officials that have tangible expe rience in the study area. Special care was taken to secure interviewees that were not financially or emotionally influenced by their past or current dealings with the events that transpired in the study area. Hence, the sele cted interviewees represente d the strongest collection of technical and institutiona l knowledge that did not have conf licted interests with the study area. Ms. Joyce Gibbs Ms. Joyce Gibbs has been employed by Pine llas County Government since 1974. In 1974 Ms. Gibbs was chosen to serve as a charter member of the Pinellas County consortium exploratory environmental pla nning committee. The exploratory planning committeeÂ’s goal was to inventory and assess the outstanding environmental risks that existed within Pinellas County based on the di rectives of Federal le gislation circa 1974. In 1975, Ms. GibbÂ’s title changed to Air Qualit y Chief of Pinellas County, and she was charged with developing the Pinellas County Air and Water Quality Division so that base line ambient analytical knowledge for the Pine llas County air shed and water shed could be completed. Ms. Gibbs was the Chief of the Air Quality Divisi on of the Pinellas County Department of Environmental Ma nagement from 1975-1986. Ms. Gibbs was charged with administering air quality polic y for all of Pinellas County from 1975-1986 and this included the commencement of a progressive ambient testing and compliance program. Ms. Gibbs was fully responsible to research, manage and enforce Pinellas
18 County air quality standards. The Air Qual ity Division expended an extensive effort attempting to determine the content of the emissions emanating from the Stauffer Chemical Corporation elemental phosphorus produc tion facility. Because of her frequent investigative inspections of the elementa l phosphorus plant, Ms. Gibbs became very familiar with the day to day operations and procedures at the Stauffer Chemical Corporation elemental phosphorus production facil ity. This thesis relied heavily on the interview of Ms. Joyce Gibbs because of her 6-years of practical expertise relative to elemental phosphorus production emissions in the study area. The interview was conducted in order to extract her long-term institutional knowledge of the project area and the heavy industry operational conditions that created adverse environmental impacts in the study area. Ms. Gibbs continues to work for Pinellas County in 2007, a nd she is currently employed as the environmental coordinator for the Real Estate Division of the Pinellas County Public Works Department. Although Ms. Gibbs is no longer a member of the Pinellas County Department of Environmen tal Management, she provides the most powerful link to the past production procedur es at the Stauffer Chemical Corporation elemental phosphorus facility during 1974-1981. During 1974-1981 Ms. Joyce Gibbs was Pinellas CountyÂ’s highest ranking air quality official that dealt with the adverse environmental impacts associated with air toxics. Ms. Joyce Gibbs was chosen as a research interviewee because of her dive rse, knowledge regard ing the production of elemental phosphorus in Pinellas County. Ms. Joyce Gibbs also possesses the intangible quality of long-term perspective which ha s allowed her to reflect on the adverse
19 environmental impacts of elemental phosphor us production in Pinellas County over a span of 33-years. Mr. Peter Hessling Mr. Peter Hessling has been employed by Pinellas County since 1976 when Pinellas County was in the earliest stages of developing an Environmental Protection Agency (EPA) sanctioned Air Quality Departme nt. Mr. HesslingÂ’s wo rk history includes making frequent air quality field inspecti ons of the Stauffer Corporation Elemental Phosphorus production plant on a complaint driven basis from 1976-1981, while under the direction of Ms. Joyce Gibbs. Mr. Hesslin g had access to the restricted areas of the study site during active producti on periods and has first hand knowledge of the adverse air quality impacts that resulted from the production of elemental phosphorus. Mr. Hessling was charged with the day to day inspections of the Stauffer Chemical Corporation facility. This required Mr. Hessling to walk amongst the steam pipes and catwalks of the facility. Hence, he became very familiar with production methodologies. Mr. Hessling was also responsible for comprehending the operational procedures of the elemental phosphorus production facility. As a result of his work charge, Mr. Hessling spent substantial time at the Stauffer Ch emical Corporation elemental phosphorus production facility (1976-1981), inspecting the furnaces, chimneys, clarifiers and elemental phosphorus nodulizers. Because of his abundance of practical experience, Mr. Hessling has accumulated a substantial amoun t of institutional knowledge relative to elemental phosphorus production in Pinellas County. Mr. Hessling has also testified under oath as an expert witn ess at public depositions regarding the 1994 Stauffer EPA Super Fund hearings held in Pinellas C ounty. Mr. Hessling progressed through the
20 various layers of the Pinellas County Air Qual ity Division and currently serves as the DivisionÂ’s Administrator. Mr Peter Hessling was selected as a research interviewee because of his level of operational knowledge regarding the day to day operation of the facility and the adverse environmental imp acts resulting from high temperature elemental phosphorus production. Mr. Charlie Ryburn Mr. Charlie Ryburn has been employed by Pinellas County since 1992 and has helped to lead the Pinellas County Depart ment of Environmental Management in the development of a pollution recovery program Mr. Ryburn is primarily charged with coordinating the remediation of hazardous wast e facilities or haza rdous waste accident sites in Pinellas County, Florid a. The pollution recovery program is also frequently referred to as environmental remediation. Mr Ryburn serves as Pinellas CountyÂ’s direct liaison to the 1994 Stauffer EPA Super Fund S ite. In other words Mr. Charley Ryburn reports directly to the Pine llas County Commission regarding the day to day development associated with the 1994 Stauffer Chemical Corporation Super Fund Site. Mr. Ryburn has intimate knowledge of the degradation of soil and groundwater relative to elemental phosphorus production in Pine llas County, Florida. Mr. Ryburn is charged with reviewing and responding on Pinellas CountyÂ’s behalf to all Stauffe r Super Fund Site environmental remediation reports and proposal s that are associated with the on-going litigation and negotiations based on the 1994 Stauffer Chemical Corporation Super Fund Site designation. Mr. Ryburn is currently employed by Pinellas County as the Program Manager of the Pinellas County Department of Environmental Management Pollution Prevention Program. Mr. Charli e Ryburn was selected as a re search interviewee because
21 of the amount of knowledge on the site, that he has accumulated he has accumulated since 1994. Interview Questionnaire It was determined that a private intervie w session based on a series of open-ended questions would yield the most informati on for the study. All interviewees were encouraged to expound beyond the constraints of any question in or der to reveal all pertinent institutional knowledge. The starti ng point for the interviews encompassed the following questions: 1). Provide your specific hist orical recollections of the Stauffer Corporation elemental phosphorus production facility in Pinellas County, Florida? 2). Describe the industrial/environmental hyg iene conditions you observed at the Stauffer Corporation elemental phosphorus production facility in Pinellas County, Florida. 3). Describe the environmental conditions th at employees were e xposed to during the operational period of the Stau ffer Corporation elemental ph osphorus production facility in Pinellas County, Florida? 4). What were the environmental conditions that the surrounding community was exposed to during the operational period of the Stauffer Corporation elemental phosphorus production facility in Pinellas County, Florida?
22 5). Describe the tangible measures that were taken to minimize the adverse environmental impact to the facility workers and the surr ounding commercial and residential communities? 6). What was/is the public opinion of the Stauffer Cor poration elemental phosphorus production facility during itÂ’s oper ational and post operational period? 7). What efforts were made at the local level in order to help assure the safety of the public relative to the Stauffer Corporati on elemental phosphorus production facility? 8). What could be done within the realm of cu rrent industrial regulatio ns to increase the safety of workers and the public relative to heavy industry? 9). What lessons have been learned from the production of elemental phosphorus in Pinellas County, Florida? The interviewees were free to expound on any issue that they knew would be relevant to the study. As a result of the openness of the interview extensive information was collected outside of the formal framework of the above noted nine questions. During the course of the interviews additional inst itutional information was collected as each question provoked more comprehensive responses. During all of the interviews it was pa ramount to follow accepted ethnographic interview procedures. The interviews were constrained by the following rules as defined by Atkinson et al (2001):
23 Listen well and respectfully, devel oping an ethical engagement with participants at all stages of the projec t; acquire a self awareness of our role in the construction of meaning during the interview process; be cognizant of ways in which both the ongoing re lationship and the broader social context affect the participants, the interview process, and the project outcomes; and recognize that dialogue is discovery and only partial knowledge will ever be attained (Atkinson et al, page, 307, 2001). The respondent(s) were passively encour aged to produce answers that are self evident in meaning. In order to accomplish th is, I tried to keep the interviewees at ease by using non-intrusive open-e nded inquiries. By not aski ng close-ended questions, the respondent(s) were given liberty to expand on an inquiry as much as they desired. By conducting an interview with exclusively openended questions it allows the respondents to gather his/her thoughts, and to concentrate on issues that are important to this research. During the interview process I viewed it as critically important to allow the respondent to freely expound on the subject matter. In or der to accomplish this, I adhered to the following guidelines for effec tive and free flowing i nquiry (Evans, et al, 1984). -Ask question(s) that cannot be answer ed with Â“yes,Â” Â“no,Â” or a simple fact. -Ask question(s) that is/are on topic. The interviewer should make open inquires to: -Give respondents greater opportunity to discuss topics re levant to them. -Gather information and help res pondents explore and clarify their concerns. -Put respondents at ease. -Facilitate elaborat ion of a point. -Elicit specific examples of general situations. The interviewer should make closed inquires: -Generally, as infre quently as possible. -Specifically, when you need informati on that is important to the progress of the interview (Evans et al, page 44, 1984).
24 As the interviewer I was fully aware that any one interview can yield a biased perspective that would be exclusive to th at individuals own particular values and paradigm(s). In order to compensate for this natural human characteristic I attempted to conduct interviews across a broad cro ss-section of informed respondents. As the interviewer, I took detailed hand written notes and made sketches/drawings to document technical details when appropriate. The sketches and drawings were used as cues to help me recall specific technical deta ils divulged by the respondents. No tape recorder was used dur ing the interviews. The interview process included the collectio n of the institutional data from the three interviewees. The compilation of pertinent data required assimilation and distillation of approximately three hours of personal interviews and the interpretation of detailed line drawings and distil ling the relevant details that were germane to the specific study. A hard bound journal book wa s used to record the dialogue of the interviews and to capture the detailed line drawings that the interviewees drew to help clarify their topic points. In many cases the inte rviewees drew descri ptive line drawings to assist the study in the interpretation of specifi c details relative to locati on geography and the areas that were adversely affected. The transcriptions followed the dialogue of the interviewees, but excluded the extended dialogue pauses to collect thoughts and non relevant dialogue such as periods when the dialogue drifted to no subject matters. Ther efore, the transcripts are not exact hand written r ecordings of every word th at was expressed during each interview. The transcripts are detailed notes and quotes taken from each of the interviewees. Direct quotes relating to th e topic questions and additional commentary verbage was captured as each interviewee respon ded to the series of questions. Research
25 data was extracted from the transcripts when the interviewees made comments that were pertinent to the over-arching research question and related sub questions. The transcripts that were derived from the interviews were scrutinized for pertinent informational details that were re levant to the over-arc hing research question and sub questions. When information releva nt to the research questions was located within the transcripts it was extracted and imposed into the supporting text of the thesis. The nine prepared interview question provided a basis of technical deta ils that were able to help answer the associated research questions. The interviewing process also prompted several spontaneous responses from the participants that provided auxiliary institutional knowledge. The spontaneous inte rview responses were also scrutinized for details that could help to answer the research questions. The interview transcripts in totality were utilized as the depository of practical c ontemporary knowledge relevant to the Pinellas County research proj ect. All details within the transcripts that were relevant to the research was extracted and imported into the research thesis narrative as supporting knowledge. When relevant direct quotes from the inte rviews and/or literature are used, and in other instances, when themes or prevaili ng lines of thought are extracted from the transcripts direct quotes are not used, but the interview is referenced. Historical Analysis Historical and Contemporary Archival Documentation and Analysis Additional information related to the el emental phosphorous processing in northwest Pinellas County was also gathered using histor ical and contemporary ar chival analysis, in
26 order to create an evolving collection of data that complimented the interview data base. The process of historic document collec tion began in April 2003 as the public was afforded access to the Federal Depository in Tarpon Springs, (Photograph 1 and 2). Photograph 1-Tarpon Spri ngs Public Library (LookingSouthward) Photograph 2-Federal Deposito ry at the Tarpon Springs Public Librar y
27 The archival research consisted of re viewing existing rese arch, mostly from technical bulletins and reports. This phase of the research utilized the resources of the libraries at the University of South Florid a, Tarpon Springs City Library (the Federal Depository for the Stauffer Super-Fund Site), the Pinellas County Department of Environmental Management techni cal library and archived file s, the City of Clearwater Public Library and the internet. Large amounts of data were located at the Federal Depository in Tarpon Springs, Florida. The research process required r eading through a large volume of technical bulletins and reports that are located at the Federal Depository. The research reading was focused in order to find pertinent elements of environmentally related topics relative to the research project. Additional research da ta was gathered from the collective library and archived files of the Pi nellas County Department of Environmental Management located in Clearwater, Florida. The archival research utilized the existing published texts and documents in order to draw together th e collective concepts and perspectives of various research works that have similarities with my site specific local research project. When historic and contemporary informati on relative to the research question and sub question was located it was extracted for the historic analysis portion of the research project. The study was able to acquire ma ny of the hard copies of historic and contemporary documents over the co urse of the research project. The documents usable by the research investigator can be considered under two broad categories: existing documents, which are not produced in connection with a specific study but are relevant to it, and elicited documents, which are produced at the in stigation of the investigator by the individuals being studied (D ohrenwend, et al, page 16, 1965).
28 Geographers who utilize ethnography are able to use the records of previous fieldwork in two ways. They can incorporate it into his/her own re search, and use it to extend their study backwards to compare past and present. They can al so use it critically to re-examine their prede cessorÂ’s interpretations and conclusions (Ellen, 1984). The historical information was derived from the agglomeration of data that initially appeared to be relevant to the ove r-arching research ques tion and sub questions. Following a more comprehensive analysis of th e collected historical data all relevant information was extracted and compiled for application. When information relevant to the research questions was located within the historic information it was imposed into the supporting text of the thesis as supporting knowledge. During the writing of the research thesis all relevant historical information was distilled and imported into the research project.
29 Chapter Four Study Area The specific area of study is located along the west cent ral coast of Florida (figure 1). The project area is located within an unincorporated portion of northwest Pinellas County that is dominated by the geographic in fluence of the Anclote River and the Gulf of Mexico. Figure 1Location of Pinellas County, Florida (Pine llasCountyGovernmentGIS,2005)

36 Geology/Pedology This section of the resear ch project is provided in order detail the physical geographic environmental attr ibutes of the project area The described geographic attributes are very specific to the research area and directly influence the potency of the adverse environmental impacts that we re imposed on the population and biologic community. The study area has experienced significant so il profile disturban ce as a result of the development of the industria l infrastructure that was requ ired to support a large-scale phosphate ore processing facili ty. Significant soil cutting and filling was conducted in the project area in order to accommoda te structure construction and railroad Photograph 7-Gulfside Elementary School (Adjacent Pasco County) (Looking Northward)
37 transportation infrastructure. The grading of the site was conducted primarily to level the land parcel in order to maximize land use for in dustrial applications. The project site is comprised of three distinct soil classifications. The site is dominated by soil rework ed by construction throughout the entire southern section from the Anclote River eas tward to Anclote Road. These made land soil(s) are anthropogenic modifications of the existing soils in the area(s). Made land (Ma) soil is frequently un derlain by buried river and sandy bay bottom and also mucky Tidal swamp. Made land is comprised of various introduced materials that can consist of shell, rock fragments, mixt ures of sand and clay that have been leveled by earth moving equipment. The introduced materials are spread over the existing native soils so that natural soil profiles become bur ied and mixed (United States Department of Agriculture 1972 Soil Survey of Pinellas County, Florida). The northern limit of the site is comprise d of Astatula fine sand. The Astatula fine sand is an excessively drained soil that was formed in relic coastal dunes. Astatula fine sand, 0 to 5 percent slopes (AfB) is an En tisol that has developed on the upland ridge of Pinellas County and it generally produces a level to gently sloping landscape. Under normal precipitation conditions Astatula fine sand will support a water table that is between (101.6cm to 152.4cm/40Â” to 60Â”) below the surface. Astatu la series are highly droughty soils. The parent la ndscape and historic soils were formed on a geomorphic feature known as the Pamlico terrace (United States Department of Agriculture 1972 Soil Survey of Pinellas County, Florida). The soil component within the study area have been worked and re-worked extensively by earth moving equipment from 1947-1981. As a result of this, the project
38 site is nearly level and supports primarily ruderal (a plant speci es that quickly recruits in waste places such as disturbed unoccupied so ils) species of trees and shrubs. Due to anthropogenic activities no natural/relic co astal dune ridges or topographic anomalies remain. Climate All parts of Pinellas Count y are exposed to the temper ature moderating effects of both Tampa Bay and the Gulf of Mexico. Pi nellas County experien ces extended periods of hot and humid weather during the summer se ason and relatively cool and dry winters. January provides the coldest weather period with average daily high temperatures of 22.2 degrees C or 72 degrees F and daily average lows of 12.7 degrees C or 55 degrees F. August provides the hottest weather with aver age daily highs of 32.2 degrees C or 90 degrees F and daily lows of 24.4 degrees C or 76 degrees F. November provides the lowest average monthly precipitation total of 4.32cm or 1.7 inches and July provides the greatest average precipitation total of 23.37cm or 9.2 inches (1972 Pinellas County Soil Survey). The Victor/Stauffer specific study area is al so highly influenced by its very close proximity to the Gulf of Mexico. During spring, summer and fa ll a dominant afternoon coastal sea breeze supports a prevailing west erly wind that moderates temperatures. Annual rainfall in Pinellas County is ap proximately 55inches/139.7 centimeters. However, local micro-meteorological phenomenon can create significant annual deviations in precipitation totals. A single tropical storm event duri ng any given year can significantly enhance precipitati on totals well above the average total. Nearly 60% of the annual rainfall total occurs from June thr ough September and tropical storms during this
39 time period can contribute significant amounts of rainfall in a 24-hour period (1972 Pinellas County Soil Survey). Rainfall in Pine llas County is rather acidic and it averages a pH of 5.15 (Pinellas County Department of Environmental Management, Air Quality Division Datum, 2005). Between September 1981 and September 1982 the mean pH value for rainfall for the Pinellas, Pasco, Hillsborough County metr opolitan area was 4.48 (Fernald and Patton, 1984). Extended dry periods occur from April 15th-June 15th and from October 1st-December 15th. Pinellas County experien ces temperatures of 32-degr ees approximately 5-10 times each year. Winter temperatures drop to 28degrees or lower approximately three times each winter (1972 Soil Survey of Pinellas County, Florida). Topography As previously noted, the study areaÂ’s natural topography has been significantly altered by earth moving equipment. The site has been historically leveled in order to accommodate industrial production and th e supporting railroad transportation infrastructure. The 1995 United States Geol ogical Survey quadrangle map indicates that the subject land parcel has two rather distinct planular uni ts of elevation. The lower planular landscape unit adjacent to the Ancl ote River averages 1.52 meters or 5.0 feet National Geodetic Vertical Datum, 1929 (NGVD) and the more landward upper landscape unit averages an el evation of 3.48 meters or 10.0Â’ NGVD. The high point on the study site is approximately 3.66 meters or 12.0Â’ NGVD (feet above mean sea level). The topographic high point of the study site is located at the extreme northeast corner of
40 the land parcel adjacent to Anclote Road (United States Geological Survey, Tarpon Springs Quadrangle Map, 1995). The study site exhibits virtually no eviden ce or erosion or mass wasting. This is in great part due to the very subtle topographi c deviations that were created when the site was leveled. The study site is comprised of very fine textur ed soil and sands that have weak cohesion qualities. The ambient soil ch aracteristics would normally create a site that would be highly prone to er osive and mass wasting influences. Land Use At this time, the 52.63 hectare or 1 30-acre Stauffer Chemical production site has been demolished except for two rema ining administrative bui ldings located south of Anclote Road. The Stauffer Chemical site is currently staffed by two security guards who are housed in one of th e two remaining administrativ e buildings during day light hours. Currently, the abandoned 52.63 hectare 130-acre site is partitioned from public access with a six-foot tall barbed wire fence on all perimeters. The perimeter fencing is posted Photograph 8-Stauffer Super Fund Site Security Building at Facility Fronta g e

42 The study site supports a sp arse collection of tree a nd shrubs. The fenced compound is mowed by Stauffer Management Co rporation staff and this action reduces the opportunity for native tree and shrub recruitment. Th e altered droughty soils support a sparse coverage of Bahia grass (Paspalum notatum ) and Bermuda grass (Cynodum dactylum ) which are mowed on an as needed basi s. A gated singlefamily sub-division named Meyers Cove is loca ted adjacent to the west si de of the abandoned Stauffer Chemical production facility. The adjacent parc el located to the south of the Stauffer Chemical facility is an operating commer cial marina that caters primarily to noncommercial weekend boat traffic. An alumi num recycling business and a concrete pipe casting business are both located on the east side of the site. The aluminum recycling business and the concrete pipe casting busi ness do not directly adjoin the Stauffer Chemical property. The area located to the east of the abandoned elemental phosphorus production facility is described as light in dustrial, public utility (Anclote Progress Energy) and commercial by the Pinellas County Zoning Department. The single exception to industrial, public utility and commercial zoning within 0.5 kilometers of the Stauffer Chemical site is the Meye rs Cove single-family subdivision.

44 Population The extreme northwest corner of Pinell as County is truncated by an extensive system of river crenulations, bayous and marine swamps that have limited the areal extent of large home site development up to this tim e. Because of this, the extreme northwest corner of Pinellas County has not seen hi gh-density development or redevelopment. Photograph 13-Public Beach and Commercial Shrimping (Mouth of the Anclote Ri ver Looking Westward)
45 The population within the res earch area has remained very stable since 1980. According to the 1980 census approximately 12,500 people lived within a one-mile radius of the research site north of the Anclote River and approximately 4,000 people live within one mile of the resear ch site south of the Anclote River (Pinellas County Planning Department Abstract, 2000). According to the 1990 census, approxima tely 14,000 people lived within a onemile radius of the research site north of the Anclote River. Approximately 4,700 people live within one mile of the research site south of the Anclote Ri ver (Agency of Toxic Substances and Disease Registry, 2003).

47 Chapter Five Results and Discussion This section is a compilation of qualitative and quantitative informational findings that has been compiled and analyzed followi ng an investigation of historic document, contemporary documents and from personal inte rviews of various officials associated with the environmental field in Pinellas Count y, Florida. Based on the analysis of the research data sources a scenario of 60-years of adverse environmental impacts to Pinellas County is demonstrated. The relationship of elemental phosphorus production and adverse environmental impacts in the study area are directly linked to the production location and the time of production. The phos phate industry of Flor ida began in 1879 when rock phosphate mining commenced in what is present day Hawt horn, Florida. The first commercial mining of phosphate pebbles occurred in 1882 within the Peace River Valley at Fort Meade, Polk County, Florida (Randazzo and Jones, 1997). The historic timetable of the phosphate industry of Florid a is more fully detailed in Appendix-I. Native Florida phosphate is an un-pure Ap atite ore that contains numerous inclusions. Florida phosphate ore is an amalgamation of mineral impurities. Phosphate formation in Florida was reliant on numer ous submergence and emergent oceanic sequences. The submergence and emergent oc eanic rise and fall e xposed the areas of Florida to nutrient rich seawater up-wellings. The oceanic up-wellings helped to create concentrations of biogenic compounds that are exploited from Fl oridaÂ’s phosphate ore.
48 The geologic amalgamation of numerous bioge nic marine sediments created a nutrient rich geologic formation that is e xploited for the latent phosphate. Native phosphate ore is not currently c onsidered to be a toxic compound. The toxic compounds within phosphate ore are realized only when it is synthetically altered by high heat and reducing conditions. The ha rsh conditions that are used to create elemental phosphorus liberate the toxic fl uorine impurity from phosphate ore. The liberation of fluorine is just one example of the cocktail of toxic compounds to which elemental phosphorus production employees were exposed. The following sections of the thesis will segregate the specific adverse environmental conditions that employees, ci tizens and the larger biologic community were exposed to during the operational and pos t operational years of the Victor/Stauffer elemental phosphorus production facility. This section of the thesis begins with the employees who worked at the 130-acre produc tion facility during its 34-year operational period. The following sections will addr ess each of the research sub-questions separately, with the questions: 1). Â“What are the adverse environmen tal impacts imposed on the employees relative to air quality, water quality and other forms of exposure in the study area?Â” 2). Â“What are the adverse environmental impacts imposed on citizens relative to air quality, water quality and other fo rms of exposure in the study area?Â” 3). Â“What are the adverse environmental impacts imposed on the non-human organisms relative to air qual ity, water quality and other fo rms of exposure in the study area?
49 These research sub-questions are examined in order to help answer the larger, over-arching research question, Â“What are th e adverse environmental impacts resulting from the production of elemental phosphorus in Pinellas County, Florida?Â” Employees Air Quality Issues This section of the research will c oncentrate on the adverse environmental conditions that are relevant to the employees that worked in the production of elemental phosphorus in Pinellas County. The production employees were exposed to the gas, fumes and dust associated with elemental phosphorus production du ring a 40-hour work week. The emissions created by the production facility produced a dverse air, water and soil quality conditions that were most concentr ated in the work area environment. This information for the following sections was extracted from the analysis of historical documents, technical references, media interviews and interviews of public environmental officials who hold specific in stitutional knowledge about the production facility. The incineration of raw phosphate ore is not a simple benign process. The melting of native Florida phosphate rock results in the liberation of toxic compounds that escape as gasses and precipitations of aeros ols. The twin 458 cubic meters/500 cubic yard capacity electric arc furnaces helped to ensure that copious amounts of gasses and dust emanated throughout the study area. A faci lity worker or resident could not escape the production facilityÂ’s ge ographically large and nearly persistent emission plume (Gibbs, 2006).
50 The large scale production of elemental phos phorus did not escape the scrutiny of Pinellas CountyÂ’s earliest environmenta l planners. During the inception of environmental regulation in Pinellas Count y the following observation had been made: The Stauffer elemental phosphorus pr ocessing plant was the only heavy industry located within Pinellas County at that time and to this day and it was without a doubt the most obvious environmental issue we faced in Pinellas County. After completi ng Pinellas CountyÂ’s environmental consortium review in 1974 we deem ed the Stauffer elemental phosphorus plant to be the greatest risk to the environmental quality in Pinellas County and the employees at the facility (Gibbs, 2006). The following quotation highlights a part icular danger to the production floor employees when a batch of phosphate ore ha d completed it producti on process. Every production batch created the n eed for a de-gassing phase. During the de-gassing phase of production large quantities of phosphorus pentoxide, sulfur dioxide gas and fluorine gas was vented from the chimney of the furnace (Hessling, 2006). This detail reveals the particular envir onmental degradation that occurred during the degassing phase. The degassing proce ss marked the end of a batch production and typically the large amounts of gas overwhelmed the undersized ventilation hoods and chimney capacity. Phosphorus pentoxide and sulfur dioxide are severe respiratory irritants and chronic exposure can lead to lesions of the trach ea and lungs. When phosphorus pentoxide is combined with atmos pheric moisture a mild phosphoric acid can be formed and may disperse in thick white clouds of smoke. When atmospheric moisture is combined with sulfur dioxide a gaseous sulfuric acid is created. When gaseous fluorine is combined with atmospheric moisture an air borne fluoric acid is created. All of the fore mentioned acidic gasses can burn and ulcerate moist eye surfaces and
51 respiratory tissues. Along with burning human tissue sulfuric acid can also damage painted surfaces of cars and structures. Fluor ic acid is a highly corrosive compound and if it is capable of etching glass. Peter Hessling highlighted several of the adverse environmental conditions that production employees were frequently exposed to during a typical 8-hour shift. The following paragraph emphasizes the risks of working on the produc tion floor after the furnaces were opened in the cooling phase. To further expand on this specific issue Mr. Pete Hessling provided the following ins titutional knowledge regarding operational procedures based on his field observations and investigations from his compliance inspections: During the furnace breeching stage of production large quantities of sulfur dioxide and phosphorus pent oxide would have been liberated outside of the chimney and onto the work area floor apron. Much of the fugitive steam was generated when blasts of cool water from fire hoses were poured onto the hot phosphate slag (Hessling, 2006). Another production phase known as the phos phate slag cooling process also put production employees at great risk. This sp ecific process exposed the workers to the greatest air quality hazard duri ng a production cycle (Hessling, 2006). Peter Hessling also indicated that the phos phate slag cooling pr ocess created large quantities of steam that contained toxic phospho rus pentoxide gas. This particular gas component would cling to the land surface du e to its' high specific gravity and would achieve densities that would obscure visibility to less than 30 feet within one mile of the production facility. Phosphorus pentoxide ga s is corrosive and irritating to mucous surfaces of eyes, lungs and skin. Anothe r major source of phosphorus pentoxide gas escape occurred when an excessively large hole was knocked out of the electric arc
52 furnace plug during the tapping procedure. If this occurred a large down draft was created and this would actively pull large qua ntities of hot phosphorus pentoxide gas out of the furnace and the chimney. This part icular operational phenomenon would create a large cloud of toxic gas that could empty the entire contents of the furnace and chimney onto the production floor. The floor producti on staff was not equippe d with any type of lung or eye protection. Add itional toxic compounds in the smoke emissions and dust included fluorine and sulf ur dioxoide (Hessling, 2006). The local meteorology exacerbated the local damage resulting from the operation as prevailing winds pushed the plume of gasses, smoke and dust east and south eastward towards the more populated City of Tarpon Springs and Dunedin (Hessling, 2006). The local prevailing winds and topography would control the path and dispersion of the gaseous emission. It was common for the dense phosphorus pentoxide gas to move gravitationally to the Anclote River. The i ndustrial releases of phosphorus pentoxide gas were never accurately measured at the Stauffe r site during the production period because there was no EPA accepted means to assess concentrations circa 1975-1981 (Hessling, 2006). According to Peter Hessling the phos phate nodule production furnace also generated large amounts phosphorus pentoxide at ground level. This condition endangered the production staff a nd all of the residents within one mile of the facility. The major problem with the phosphate nodule furnace was that it did not have effective dispersion designed into the chimney structure. The poor chimney design allowed clouds of phosphorus pentoxide, fluorine and sulfur di oxide to persist in the vicinity of the facility for extended periods of time with no means for rapid dispersion (Hessling, 2006).
53 Peter Hessling also stated that in ma ny circumstances effective chimney and hood systems can move the toxic contaminant to at mospheric heights that allow meteorological dispersion processes to dilute the pollutant ove r a large geographical ai r shed area. At the Victor/Stauffer production facility observationa l evidence indicates that the geometry of the chimney and ventilation hoods were poorly designed and overwhelmed and atmospheric dispersion was not exploited (Hessling, 2006). Joyce Gibbs stated that the environmental risks associated with the production of elemental phosphorus were numerous and in cluded adverse conditions for workers and the residents in the vicinity of the pollutant plume of the production facility. The workers in the production facility were exposed to conditions that pr edisposed them to: asbestosis, chemical burns, physical burns, fluorosis lead poisoning, radium-226, silicosis, phosphorus intoxication, sulfur dioxide, pho sphorus pentoxide, phosphine gas and fugitive dust containing an amalgamati on of by product materials (Gibbs, 2006). The above list of toxic agents is not clini cally conclusive as there are synergistic compound reactions that have not been researche d. Asbestos is a toxi c agent that is well understood in the context of 2007. However, in 1947 the risks associated with asbestos were not well understood or published. The ex treme temperatures and pressures created during production at the Victor/Stauffer fac ility caused pipes and furnace structures to fatigue. As a result of this, frequent repair patching w ith asbestos cement was conducted by production workers. Peter Hessling stated that the production of elemental phosphorus required the use of extremely high heat and this imposed great heat stresses on the facilityÂ’s pipes and heat connections. In order to repair heat fatigue damage, asbestos cement was used
54 extensively in the production plan t. Asbestos cements were al so used liberally to protect critical components from the high heat enviro nment. Steam pipes and all observed voids in the furnace structures were coated or plugged with asbestos cement compounds. The asbestos compounds would even tually deteriorate and become fractured in and around the furnace production area. On rare occasions the asbestos plug that held the electrode in place would fall into the furnace and it would be vaporized and expelled in the chimney emissions. The vaporized asbestos cement would be di spersed through the chimney where it would settle over the adjacent properties in the area. There was never any accounting or inventory records keep so that asbestos cement volumes could be measured (Hessling, 2006). Asbestos becomes a significant health risk to humans when it is fractured and dispersed into the air column. When asbe stos fragments are inhaled by humans the asbestos filaments lodge deeply in the lungs and in order to wall of irritation the lung tissue responds by creating cyst ic tissue. Long term exposure to air borne asbestos can create asbestosis with is an untreatable chroni c lung disease (Gibbs, 2006). The dispersion of vaporized asbestos crea ted a significant respiratory risk to the entire study area. However, production workers essentially worked in an extremely dusty environment that included minute fragments of asbestos. The ab sence of respiratory protection placed the production workers at gr eat risk for asbestosis. Exposure to asbestos fibers can also create a conditi on that predisposes humans to lung cancer. Over time the fibers (of asbestos) can work loose and, because they are small enough to float freely in the air or be inhaled, asbestos usage is now strictly controlled; exposure to it s dust can cause cancer (Lindley and Moore, 1998).
55 In order to shelter the public from the a ppearance and operational emissions of the elemental phosphorus processing plant it was conveniently tucked aw ay in the relatively unpopulated northwest corner of Pinellas County. However, the hazardous emissions could not be partitioned and were dispersed locally by meteorological processes. Joyce Gibbs stated, During my public health driven insp ections at the Stauffer Chemical elemental phosphorus facility from 1975-1981 I was taken back by the extreme dirtiness of the site. This was a real dirty heavy industry and Pinellas County had no other comparab le facility. I was most amazed by the dust. The site was frequently shrouded in thick clouds of dust and fumes. I never observed any employ ees wearing lung or eye protection equipment. Following the completion of a batch the production furnaces would be tapped at the base using a battering ram. At this stage molten phosphate/silica slag would boil out of the furnaces along with large clouds of phosphorus pentoxide and fl uorine gas. This was the most dangerous phase of the production as the vast amounts of burnt phosphate and slag would pour out of the furnace a nd onto the floor of the facility at temperatures near 3,000F. Plant wo rkers were frequently burned by the steam and molten slag that could spla sh outside of the containment walls on the production floor. Worker s were also burned by elemental phosphorus. Related to this Joyce Gibbs said: The overhead vent hood could not cont ain the large volume of gasses and fumes that poured out of the furnace during the breaching event. Because of this, there were frequent larg e clouds of phosphorus pentoxide that would loom over the immediate area of the facility. When phosphoric acid vapors are combined with abunda nt atmospheric moisture you create phosphoric acid clouds. Pr evailing winds would generally push the phosphorus pentoxide cloud plumes to the southeast over the adjacent Flaherty Marina and towards th e Tarpon Springs population (Gibbs, 2006). In the preceding quotation, the issue of empl oyee safety is more fully discussed. The completion of each batch of elemental phosphorus included the need to break open the face of the furnace so that the molten slag ma terial could be cleared from the furnace.
56 It was during this phase of production that em ployees and residents in the project area were at the greatest environmental risk. As the furnace was tapped or broken open the specific gravity forces pulled large quantities of gasses from the belly of the furnaces. If the furnace was breached with too large of an opening the entire chimney could be drained of gasses and in this way the chimne y and furnace gaseous constituents could end up at ground level for human exposure. The pervasive dust and gas clouds contai ned a cocktail of synthetic compounds that are toxic to humans. Employees at the production facility had no way to effectively shield their bodies from the airborne chem ical compounds. As a result of this, the employees were at great risk. The vast majority of employees did not work at the produc tion facility for extended periods of time. The turnove r rate was very high and it does not appear that any employee worked in the production area for more than three years. The industrial safety conditions were very poor. Some employees wore dust masks but ther e were no respirators or face protections used. An issue that I was concerned with was fluorine poisoning as we had no accepted way to sample and quantify for this highly toxic compound. Employees w ho are exposed to fluorine will commonly develop dental disease(s) that can include weakening of the jaw. The employees would frequently smoke during breaks and lunch and it is possible that they i nhaled fluorine as a cro ss contaminant from their cigarettes (Gibbs, 2006). Joyce Gibbs also added that the Stauffer Chemical Corporation had a rudimentary on-site dental operatory where it appeared that dental work was conducted. People affected with phossy-jaw experience an eros ion of the jaw bone stru cture and total tooth lose can occur along with mandible infectio ns. The Stauffer Chemical Corporation provided in-house dental care for its employees. There was a dent al chair in th e building. A dentist facility was located in the employeeÂ’s locker ro om building. It would seem
57 logical that oral disease was managed by th e company. The onsite dental facility was most likely used to resolve issues related to loss of calcium in the jaw bone and other dental diseases associated with fluorosis (Gibbs, 2006). Another issue of concern is the adverse e ffect on kidneys from excessive fluorine absorption. Two areas are of concern in regard to fluorine and kidneys. First, a fairly substantial body of research indicates that people with kidney dysfunction are at increased risk of developing some degree of skeletal fluorosis. Second, a small and inconclusive am ount of research suggests that fluoride may actually cause or aggrav ate kidney disease (Hileman, 1988). The workers at the Victor/Stauffer elem ental phosphorus production facility were exposed to a collection of air quality hazards as they made repairs to keep the furnaces functioning. Former Stauffer Chemical Corpor ation workers tell stor ies of spending their work day in irritating gas clouds. The past em ployees recall moving bags of asbestos that would frequently break open. The workers clothes were fu ll of a white dust that was created from the discharge of the giant fu rnaces. For many of the years the plant operated there was no breathing protection as la ws did not require breathing protection for workers. Worker turnover at the el emental phosphorus plant was significant. StaufferÂ’s employee records indicate that only 25% of the employees stayed at the elemental phosphorus plant for more than one year. The 2003 ATSDR study concludes that employees must be protected by tough occu pational hazard laws that have the ability to guard the employee from health hazards th at they may not be fully aware of. The study also concluded that past employees at the Victor/S tauffer elemental phosphorus plant must receive on going health care since there is a high propensity for lung disease in
58 this group. On going heath care for the past employees might help them to live more extended lives with more comfort (St. Pe tersburg Times Editorial, December 29, 2005). Joyce Gibbs provided the following comment regarding to the adverse conditions that workers were face with: It was common for employees to recei ve both chemical and thermal burns while working in the production furnace facility. I saw several employees who had significant burn scar tissue on their arms from what appeared to be numerous burn events. Woun ded flesh provides an opening for elemental phosphorus and fluorine absorption into the blood stream (Gibbs, 2006). The greatest risk for huma ns from elemental phosphorus comes from frequent dermal exposure and associated absorption. Elemental phosphorus is highly soluble in the lipid environment of fatty tissues. Because of its enhanced solubility in fatty tissue many health experts believe that elemental phosphorus dermal injuries result in delayed wound healing. The absorption or ingesti on of elemental phospho rus can result in pathogenic changes to the live r and kidney. Absorption or fr equent small i ngestions can result in subtle to signifi cant changes to normal blood chem istry. Assimilated elemental phosphorus can result in increased blood phosphorus levels that are capable of replacing the essential calcium content in the blood chemistry. The reduction of calcium in the blood chemistry and the elevation of phosphor us levels in the blood chemistry can produce electro-cardiographic changes to the hear t. Frequent consumption of very small amounts of elemental phosphorus can create pa thologic changes in the kidneys, liver and fatty tissues and can lead to cardiac disr uptions (Emedicine; eResidency.net, 2003). Numerous workers and residents have b een adversely affected by the 34-year period of active production. Most likely there are hundreds of people who lived and
59 worked near the plant who have paid a terrible price in health related issues that they may have never been aware of. Stauffer workers were exposed to asbestos, sulfur dioxide, phosphorus pentoxide and elemental phosphorus bur ns that could pred ispose them to an increase risk of cancer and other health ri sks. Dangerous levels of arsenic and radium in the soil at the Stauffer site may become a future health hazard if residential development is allowed to occur there (Rondeaux, 2003). Ra dium-226 is a particular long term hazard in the study area. The next paragraph explains the risk to elemental phosphorus workers from radium-226. Processing and slag waste handling in the Florida phosphate industry is associated with (radium-226 derived) radiation levels of concern for workers and the public. The level of (lung and dermal) protection for these groups should be more similar to the level of protections that is the state of the art in other industries particularly the nuclear industry (Connet, 2003). Fluorine intoxication is an accumulative health risk that would have pervaded the entire workplace environment. The vast quantities of processed Apatite would have liberated up to 54,545 kilograms or 120,000 pounds of fluorine gas each day based on the production capacities of the twin arc-furnace facilities. Water Quality Issues This research was unable to collect tangible data relevant to water quality that was adverse to the workers of the Victor/Stau ffer production facility. The Victor/Stauffer facilities eating and drinking facilities we re not open for public inspection during the production years of 1947-1981. Because of the lack of access to water quality information in the production area the research will focus on water quality issues in the citizenÂ’s section of the research outside of the production facility foot print.
60 The production workers were exposed to very hazardous conditions during a 40hour work week. Even lunch hours and br eaks for production workers provided no escape from production dangers as most em ployees remained in dusty clothing and frequently would drink, eat or smoke with a cocktail of toxic agen ts covering their face, hands and hair. Smoking ciga rettes during work breaks w ith elemental phosphorus or fluorine contamination would have posed anot her significant health risk for production employees. When employees returned home work clothes could ha ve been laundered with other family members clothing. Co mbining work clothes and non-work clothes during laundering would have cr eated an opportunity for cross contamination of asbestos, fluorine, lead, radium-226, elemental phosphorus and silica to non-workers. The next section, related to research sub-question #2, will focus on the adverse environmental conditions that the citizens were expos ed to. The citizens in most cases were living as residents in the project area and therefore were exposed to the adverse conditions up to 24-hours a day. Citizens Air Quality Issues This section of the research concentrat es on the adverse conditions that are relevant to the citizens in the vicinity of the project area. The citizens in the project area were exposed to the gasses, fumes and dusts that are associated with the production of elemental phosphorus during its existence in Pinellas County from 1947-1981. The emissions created by the production of elemen tal phosphorus produced adverse air, water
61 and soil quality conditions that existed in the study area almost continuously for the residents. The following paragraph provides additional evidence as to the geographic extent and concentration of the elemental phosphorus production toxic byproducts. In 2003, the St. Pete Times printed an article outlining the known extent of gaseous adverse environmental impacts that were emitted from the Stauffer Chemical elemental phosphorus processing plant in nor thwest Pinellas County. During furnace venting events sulfur dioxide levels of great er that 860 parts per billion were measured within 1.5 miles of the plant at ground level. Sulf ur dioxide is considered detrimental to humans at levels of 100 pa rts per billion or above. Th e 860 parts per billion that frequently occurred during furnace venting woul d have represented a severe health risk for all human habitation. At distances of up to 3.0 miles from the elemental phosphorus production plant sulfur dioxide concentration levels at ground level ranged between 500840 parts per billion. At distances of up to 4.0 miles from the plant sulfur dioxide concentration levels at ground level ranged between 100-500 parts per billion. Current ATSDR standards reveal that su lfur dioxide in concentratio ns of 100 parts per billion or more might cause constricted airways in huma ns. There has also been strong empirical evidence collected by the Pinellas County De partment of Environmental Management that indicates sulfur dioxide gas in concentrations of up to 100 parts per billion may have drifted as far south as Dunedi n and Clearwater. The findi ngs would indicate that the venting of the production furnaces was adversely impacting the human communities up to 9 miles away from the emission source (Rondeaux, 2003).
62 In the 2003 St. Petersburg Times article (Rondeaux, 2003) the following information was presented regarding the lingering adverse effect of a dverse air quality in the study area: ATSDR scientist findings postulate that there are still legitimate health concerns regarding the abandoned Stauffer elemental phosphorus plant. The scientist are recommending that al l people who worked or lived near the plant or those who attended Gulf side Elementary School should be receiving regular medical check-ups. The research scientists are of the opinion that local doctors should be on the wa tch for lung disease or cancer. In addition to this, the ATSD R scientists advise that Stauffer Chemical employees were exposed to asbestos, fluorine, lead, phophorus pentoxide, sulfur dioxide and variou s synthetic compounds with inherent health risks. People who lived, worked or went to school within one mile of the Stauffer Chemical facility during the operational years were exposed to toxic sulfur dioxide. According to the 1980 census it is estimated that 6,000 residents lived near the Stauffer elemental phosphorus processing plant. Sulfur dioxi de levels were recorded at up to 8 times greater than safe thresholds for human habitation. People in the project study area with predisposed respiratory disorders would have suffered from the compounding effects of coughing fits, wheezing, and shortness of breath. Air quality mon itoring in the project area since 1977 indicates that sulfur dioxide levels would frequently reach 840-parts per billion. Sulfur dioxide levels of 100-parts per billion can cause significant constriction of air passage ways. It is believed that people within the project study area during the opera tional years from 1947-1981 were exposed to an increased risk of cardiovascular disease (Rondeaux, 2003). The previous paragraph alludes to the high density of pollutants that were dispersed at ground level where Pinellas County Department of Environmental Management air quality monitoring stations c ould quantify the contamination quantities. The effective dispersion of toxic gasses requires a chimney system that can exploit the influence of local prevailing winds to dilute industrial toxins over large geographic areas. Current chimney technologies utilize scrubbers to help reduce the dispersal of toxic agents (Hessling, 2006). The study confirms that the Vi ctor/Stauffer production facility was equipped with ineffective chimney geometry, overwhelmed ventilation hoods and no
63 effective scrubber system and this allowed plum es of polluted air to concentrate within a relatively small geographic air basin. Another example of the ineffective chim ney geometry at the Victor/Stauffer facility is provided in the following quote from a Pinellas County Government air quality official. During a Florida Department of Environmental Protection inquiry of air pollution concerns at the Victor/Stauffer production facility, Peter Hessling of the Pinellas County Air Quality Division told an investigation ombudsman: To the best of my knowledge, they (t he Stauffer Chemical Corporation) never actually completed an emissions stack certification test while I was inspecting the facility. Somethi ng always went wrong, something was missing or didnÂ’t work. The main problem was when they tapped the furnace. It looked like the gates of hell glowing in the dark, it gave off steam and lots of emission-phosphorus pentoxide (Agency for Toxic Substances and Disease Re gistry, 2000). The high temperatures furnaces at the production facility frequently imposed smoke and gasses at ground level as a result of poor chimney design and geometry. The smoke stack geometry combined with ambient meteorological dynamics created adverse environmental impacts outside of the produc tion facility. The stack design did not exploit meteorological ascendance and because of this dispersion of fumes was imposed to the local community in hi gh concentrations. The poor st ack design resulted in poor vertical smoke and gas dispersion. The smoke stack geometry deficiency imparted local horizontal dispersion of fluor ine gas and phosphorus pentoxid e gas throughout the project area at ground level and up to 8 miles down wind of the production facility (Hessling, Gibbs, 2006). The plume of fluorine gas that was deri ved from elemental phosphorus production was never accurately sampled or analyzed during the years of production from 1947-1981
64 (Gibbs, 2006). Fluorine gas woul d have created an antagonistic health risk to all humans and biologic communities thr oughout the study area air shed. Within the phosphate industry uninte nded fluoride dispersion remains a significant adverse environmental liability. The basis of the adverse environmental liability is primarily the result of the processing of raw phosphateÂ’s unique chemistry. Raw phosphate ore derived from Florida mine s can contain up to 4% fluoride or 40,000 parts per million (Connett, 2003). The residents in the research study area were shielded only to a very small degree by geographic distance from the electric arc furnaces as local wind patterns moved the contaminants over much of northern Pinellas County. The primary risk to the resident population was the daily inhala tion of sulfur dioxide, phosp horus pentoxide and fluorine gasses that were contained in the gaseous and dust dispersi ons that emanated from the furnaces in large quantities particularly during the furnace degassing and tapping procedures. The desired vertical ascenda nce of gasses and aerosols was frequently inhibited during night time operations as lo cal meteorological phenomenon produced low dispersion dynamics. The daily exposure to th e mixture of toxic gass es was of sufficient potency to cause: chronic asthma, burning of eye tissues, coughing f its, sore throats, shortness of breath, possible he art and lung damage and fluor osis. Residents with preexisting heart or pulmonary disease would have been at an even greater risk of adverse health (Gibbs, Hessling, 2006). As further evidence of the adverse ai r quality in the study area Ms. Gibbs provided the following recolle ction as to the se verity of the toxic compounds that frequently shrouded the project area outside of the production compound.
65 Old photos I observed that were taken by the Flaherty family showed that visibility on the adjacent Flaherty Marina was under 30-feet following a furnace tapping event. I saw a picture that showed an obscured view of a child riding a tricycle who was only 30feet from the camera. The picture was taken only a few minutes after a furnace tap event. Depending on atmospheric conditions it was possible for the area to be shrouded in a phosphorus pentoxide cloud for more th an 3-hours. Phosphorus pentoxide is highly irritating to the lungs and trachea. The normal moisture contained within the lungs and trach ea can create phosphoric acid burns to the lungs and trachea. The producti on site and surrounding community was terribly dusty and it was inescapab le. Large accumulations of residual phosphorus dust was accumulated everyw here. The public was frequently exposed to huge clouds of sulfur dioxide, phosphorus pentoxide and fluorine gas. It was the public who kept us informed based on very frequent complaints of air quality. People had trouble brea thing as a result of the dense clouds of phosphorus pent oxide gas. The sulfur dioxide gas concentration issue was very concerni ng to us as a public health risk. When the biologic moisture source of the lungs and trachea are exposed to sulfur dioxide gas a sulfuric aci d compound is formed within the respiratory system. Sulfuric acid in the respiratory system is highly corrosive and could cause ulcerations (Gibbs, 2006). The previous quote provides a tangible ex ample of the air quality conditions that residents and workers were exposed to during the daily operational di scharge cycles. The local atmospheric conditions are mentioned as a factor that exacerbated the residence time of the toxic clouds. The local meteorology of the project area is strongly influenced by both sea breeze and land breeze phenomenon. During spring, summer and fall the effects of land breeze and s ea breeze are magnified and become the dominant diurnal weather phenomenon. Unfortunately, the land and sea breeze phenomenon creates extended periods of slack air movement be tween commencement of land and sea breeze development. It is during the 3-4 hour sl ack breeze period that toxic dust and gasses would not be dispersed by pr evailing wind phenomenon. It is under the diurnal slack breeze conditions during spring, summer and fa ll that the greatest environmental degradation occurred.
66 Three months after the Victor/Stauffer plant came on-line the residents were already aware of their degraded environment. In June of 1948 the residents in the study area initiated a law suit agains t their new industrial neighbor. The law suit was supported by the deposition of three prominent local residents who had become aware of a sudden and alarming change in the local environm ental condition. Mr. J. M. Turnpaw a local boat repair company owner provided the following observations of the adverse environmental conditions he believed were caused by the gaseous emission emanating from the Victor Chemical Works elemental phosphorus production facility in 1948. I noticed the lead paints or anything you put on the boats they would discolor, and sometimes would be spotty or kind of blurry on the paint and I went over it two or three times to try to catch it, if it wasnÂ’t quite dry. I varnished several boats like that an d noticed the dust and smoke coming from over there, and you could take hold of it just like a piece of paper and pull it off the boats (Wilson, 2000). When asked how long the adverse air qua lity problem lasted, Turnpaw stated, That all depends a good deal on the conditions of the weather and the winds, and with other conditions. I noticed it more with a west or northwest wind, I get a gas smell in the atmosphere. When asked if the plants emissions aff ected his health and if he coughed as a result of the emissions, Turnpaw replied, I cough quite a bit and my mouth is dry and tasted like a mouth full of copper (Wilson, 2000). Mr. Turnpaw wa s not the only citizen that witnessed the dangerous ai r quality associated with the production facility. The adjacent human community was a direct recipient of the s ynthetic adverse air quality. In several cases the adverse air quality conditions were so deleterious that the public ducked for cover during periods when local meteorology and production practices
67 made outdoor activity impossible. The followi ng synopsis is an example of the adverse conditions that the public were exposed to on a daily basis. Mr. Everett Trader who worked just a few hundred feet from Stauffer at Sun Coast Paving provided his recollections as to the day to day air quali ty conditions within the research project area he worked in. Mr. Trader remembers observing the daily occurrence of thick yellowish-white smoke that would descend over the Sun Coast Paving where he worked in the vicinity of Anclote Road and Wesley Avenue. The gasses and vapors in the air made it difficult to br eath for the Sun Coast Paving employees. The employees of Sun Coast Paving would retreat to the safety of their air-conditioned work trailer so as to escape the caustic clouds of dust and gas coming from the Victor/Stauffer production facility (Rondeaux, 2003). They used to call it blow-off. When it would get bad, IÂ’d tell everyone to come in. They would duck in the tra iler and then about a half an hour later someone would stick their nose out to see if it was all clear (Rondeaux, 2003). The prevailing sea breeze would push toxic dust and gas plumes eastward and south eastward in the direction of the City of Ta rpon Springs. It is for this reason that the more populated City of Tarpon Springs was vul nerable to a degraded air quality and dust accumulation during the extended period Victor/Stauffer elemental phosphorus production. Joyce Gibbs provided the following deta ils relative to operation methodology. The Stauffer elemental phosphorus processing plant worked on three 8-hour shifts per day. The Stauffer plant would attempt to co mplete a maximum number of batches per furnace during the non-peak hours. This was done so that Stauffer could benefit from
68 off-peak energy costs associated with Florid a Power. The night time operations would result in gas and fume releases when local wind conditions would be dead calm and this especially true in the summe r weather season. It was dur ing the night time operations that much of the production emissions would go visually unnoticed Unfortunately, the residents and workers were exposed to a longer periods of phosphorus pentoxide exposure during night operations. The el emental phosphorus production plant used so much electric power that it would frequently consume more energy than Florida Power was equipped to provide to its total clientele. Due to its large consumption of electric power; parts of Pinellas County would be exposed to brown-outs when the Stauffer production plant was operating at full capacity. The Florida Power pl ant located north of the Victor/Stauffer facility also contributed to some of the poor air quality in the project area however itÂ’s contributions we re relatively small (Gibbs, 2006). The 24-hour production of elemental phosphor us would have spanned two periods when local winds would normally experience stagnant or slack periods. During night time period from sunset to midnight local meteorological phenomenon processes produce a period of slack winds. In addition to this the other period of slack winds occurred after sunrise and lasting into early afternoon prior to sea breeze development. The morning period of slack winds frequently lasted fo r up to 6-hours. When afternoon sea breezes developed the air parcel over the project area would be pushe d eastward and south eastward towards the more popul ated Tarpon Springs city limits. The sea breeze meteorological phenomenon would enhance gaseous disper sion in the study area.
69 When asked what were the primary pollution constituents of the emissions of the Stauffer elemental phosphorus production plant that may have been present in the surrounding communities? Joyce Gibbs responded: Air quality monitoring in the late 1970s was in its infancy. There were very few ambient air standards on the books. Because of this we (Pinellas County) monitored primarily for sulfur dioxide as it was better understood. We were not capable of sampling for fluorine gasses. Pinellas County installed th e first air monitoring st ation in the county just south east of the Stauffer property. We were concerned about sulfur dioxide, phosphorus pentoxide and in pa rticular fluorine. In the 1970s there were no accepted methods for mon itoring fluorides and there were not any standards for air quality re lative to fluorine. We tried to understand the facility and the contaminants it was producing. We were fortunate that the plant did not create organic solvent materials. The inorganic compounds were materials we were more comfortable in diagnosing (Gibbs, 2006). The previous quotation pr ovides framework to the fact that air pollution determinations were not well formulated during the entire time period that the Victor/Stauffer production facility was in ope ration. In the contex t of 1948 there was no government oversight for air pollution issues in the study area, hence it was difficult to assess the effect of discharges on the ar ea surrounding the facility. However, citizens provided their own qualified assessment of the adverse environmental impact resulting from elemental phosphorus production. The resident Mr. Mickle r provided his own qualified description of the adverse ai r quality in the study area (Wilson, 2000). When asked about the smell of the gaseous em issions from the Victor Chemical Works, Mr. Mickler responded: Well, it donÂ’t smell like sulphur [sic]. It smells like a burnt phosphate to me. Of course, knowing that there is phosphate there, it makes you think of that more than anythi ng else. It makes your thro at dry, and you taste it, and it tastes kind of coppe ry. I get asthma from it, just like Mr. Crider stuffed up yesterday [sic]. I can go out here and get in the way the wind is
70 blowing and be in it three minutes a nd have to take something for my throat. Yes sir, I cough (Wilson, 2000). Through time public safety concerns grew in the vicinity of the elemental phosphorus production facility. Because of the mounting qualitative evidence of environmental concern Pinellas County in itiated an EPA sanctioned air quality quantitative monitoring program in the proj ect area in 1977. Air sa mples were collected at the southeast corner of the study area fo r specifically sulfur dioxide emissions. Samples were collected by a 24-hour bubbler device and a 3-hour continuous monitoring device. The air sampling indicated that sulf ur dioxide levels in the air exceeded the Florida State standard until th e plant facility began to sh ut down operations in 1980. Following the gradual shut down of the produc tion facility there was a significant decline in sulfur dioxide levels (A ir Pollution from the Stauffer Chemical Phosphate Plant, December 29, 2000, ATSDR). Frequent complaints from the public were received by the Pinellas County Department of Environmental Management Air Quality Section. The public was clearly concerned about their physical health and in pa rticular air quality concerns. In order to address the publicÂ’s concern site inspectio ns were made to ascertain air quality. Joyce Gibbs stated: We made regular site inspections to the Stauffer production facility. We responded to the numerous complaints of the citizens and we installed the first air quality monitoring station in Pinellas County just outside of the production facility. Pinellas was not ab le to gain the s upport of the FDEP regional office in Tampa or the Ta llahassee office and this was very frustrating. Without the support of the State of Florida we were unable to impose effective regulatory actions The mining industry had numerous shielding provisions within law and policy that are administered by the State of Florida. We did not get the active support from the State of Florida. We did what we could at th at time and you have to keep in mind
71 that air quality issues were in their infancy and they had not been able in most cases to challenge accepted industrial standards. In many ways our hands were tied. As I mentioned before, there were no accepted monitoring methodologies for fluorine (Gibbs, 2006). The adverse air quality in the study area ha d not registered with the Pasco County School Board when it came to finding a locati on for a new elementary school. To expand on this point Mr. Ryburn stated that: The entire elemental phosphorus production issue from 1947 to present is a direct result of the failure to see the long-term adverse implications of dirty heavy chemical industry. Pasco CountyÂ’s Gulfside Elementary School was built in 1977 within approximately 2,000 feet of the established Stauffer Chemical elem ental phosphorus production plant. The Pasco County School Board was fu lly aware of the proposed school location relative to the existing activ e Stauffer plant. The Pasco County School Board was most likely looking fo r inexpensive real estate to build a new elementary school. Unfortunatel y, the low real estate cost for the Pasco County public school came within a degraded environment. The final environmental price may neve r be known for the students and teachers who breathed the degraded air for over four years (Ryburn, 2006). The previous comment provides a perspectiv e on the lack of understanding as to the pervasive dangers associated with the pr ocessing of phosphate ore. It had been common knowledge from (1947-1981) that only fertilizer was ma nufactured at the Victor/Stauffer elemental phosphorus production plant. It was not well understood that numerous synthetic compounds were eman ating from the elemental phosphorus production facility and were greatly enda ngering the citizens w ithin project area (Hessling, 2006). The physical geography within the projec t area supported vari ous underpinnings that made for a unique elemental phosphorus contamination scenario. The close proximity to the Gulf of Mexico places the research area under the pervasive influence of
72 a sub-tropical maritime climate and micro-climat e. Prevailing wind patterns in the study area are influenced by diurnal sea breezes that ar e the result of the close proximity of the Gulf of Mexico and the uneven heating of land mass versus an adjacent large water body. The persistent sea breeze within the project area had the propensity to push gas and dust dispersals to the east and southeast over the more populated area of greater Tarpon Springs. Cold fronts during the late fall a nd winter produce prev ailing northwesterly winds which also would have moved gas and dust discharges to the east and southeast over populated areas. The local meteorology had the propensity to move quantifiable chemical discharges as far south as Dunedi n, Florida which is approximately 8 miles to the southeast of the Stauffer/Victor elementa l phosphorus production fa cility. Therefore, it can be stated that the adverse influence of elemental phosphorus production occurred in quantifiable amounts up to 8 miles south a nd southeast from the production facility discharge location. Water Quality Issues This section of the study will emphasize the adverse conditions that have been imposed on the water resources of the citizens of the project area. The following paragraphs is from a Federally funded 1994 Stauffer Super Fund site synopsis of the various layers of adve rse environmental conditions present in the study area, as summarized by the Federal Re gistry in 1994. The synopsis was created shortly after the project area was designate d as an EPA Super-Fund site in 1994. The following paragraphs from the findings of th e Environmental Protection Agency (EPA),
73 highlights the environmental vulnerability relative to severa l physical geographic characteristics. The Stauffer Chemical Super Fund site study area is located in an industrialized area between Anclote Boulevard and the Anclote River in Tarpon Springs, Pinellas County, Florid a. The Stauffer Chemical Super Fund site is approximately 1.6 mile s east of the Gulf of Mexico. The Stauffer Chemical Corporation purchased the production facility from the Victor Chemical Works in 1960. During the years of operation, a number of processing wastes were disposed of on the site. A system of seven unlined lagoons, about 600 feet from the Anclote River, received discharges of waste, sc rubber liquid and phosphorus enriched water, as well as overflow from a calcium silicate slag pit. At some time two of the lagoon p its were dredged, and the dredged material, composed of calcium sulfat e/sulfite, calcium silicate, calcium fluoride, phosphate sand, and calcined phosphate dust was placed in two piles approximately 40 feet from the Anclote River. Other on-site disposal activities in cluded the dumping of furnace dust in an isolated pond and the burial of 900 drums of cal cinated phosphate sand consisting of 20% elemental phosphorus. Over 500,000 tons of chemical wastes were disposed of on the site between 1950 and 1979. The site is underlain by a surficial/vadose aquifer composed primarily of sand and the Floridan/phreatic Aquifer composed of limestone. Water is reached at an average depth of 8 feet below the land surface. The Floridan Aquifer is encountered at 17 to 37 feet and is approximately 100 feet thic k in the area of the site. On-site monitoring wells into both aquifers are contaminated with barium, chromium, lead, vanadium, zinc, copper and arsenic according to EPA tests conducted in 1988 and 1989. An estimated 8,500 people in the Tarpon Springs area receive drinking water from 23 public wells located within 4 miles of the site. Because of the depths of the aquifers, all drinking water wells within 4 miles of the site are potential targets. The EPAÂ’s 1988 and 1989 tests also detected most of the same heavy metals in the Anclote River. Surfac e water runoff from the facility could flow south/southwest and enter the Anclote River, which is used for fishing. From there, the Anclote Ri ver flows 1.6 miles and empties into the Gulf of Mexico. Although no surf ace water intakes are located along the drainage pathways of the site, nu merous county parks, state parks and beaches are extensively used. In add ition, several wetlands that support a number of endangered and protected sp ecies are located along the surface water pathway (Federal Regi ster Notice: May 31, 1994) ( URL:http://www.epa.gov/oerrpag e/superfund/sites/npl/nar1328.htm ).
74 The previous paragraphs provide a poi gnant summary of the collection of synthetic toxic compounds that were introduced into the environment as a result of high temperature elemental phosphorus production. The various constituents of production degraded the study area ground water and surf ace waters. Previous sections of this research have revealed the co llection of compounds that de graded the air quality. The combination of degraded air and water quality had adverse effects on the human population. However, there were additional organisms that were also damaged as a result of the footprint of anthropoge nic pollution. The extensive si ze and density of the toxic compound plume also damaged and killed plant communities and bovine livestock. Charley Ryburn stated that: The vast majority of the long time resi dents in the vicinity of the Stauffer production facility had relied on private wells that provided for their domestic potable water needs. All of those wells as of 1994 have been deemed to be contaminated. Residents had used potentially contaminated potable water sources for approximately 47years (Ryburn, 2006). The local geology posed an additional risk to the residents who used local well sources for potable water. The historic geologic processes within the project area produced a thin veneer of Holocene ocean ic sediments that were deposited over Pleistocene limestone. The mantled Karst landscape and the asso ciated ground water resource can be easily contaminated by materials that are stock piled at the surface or that have been buried. Acidic compounds such as sulfuric acid or fluoric acid that are introduced into a Karst landscape can hasten na tural dissolution proces ses that are usually dominated by mild atmospheric nitric acid. The Karst landscape in the study area
75 predisposes the residents to a much higher ri sk of ground water contamination when toxic materials are not effectively segregated from the surficial/vadose or Floridan/phreatic water resource. Karst environments can pr ovide copious amounts of water that can be easily contaminated due to the juvenile nature of the local water resource. In this regard, the project area presents a geologic/hydrol ogic condition that could greatly endanger human health. The specific geology of the abandoned produc tion site has produced considerable uncertainty for the EPA, Stauffer Corporat ion and the residents of the surrounding community. The thin veneer of soil that was deposited ove r the Hawthorn Formation has been altered for construction and from 1947 until 1981 had been used as a subterranean means of disposal for industrial by-products. Elemental phosphorus has an extremely persistent chemical identity (10,000-year ha lf life) when it is contained within an anaerobic (oxygen deprived) environment. In order to keep the extremely toxic elemental phosphorus contained the Stauffe r Management Co. has contracted with various geological consultants to verify the ge ologic integrity of the project area relative to a mound and cap proposal. The following section provides excerpts from recent geophysical reports. The most recent groundwater report studied among other things, the layer of clay, or confining layer, that separates the shallo w (vadose) aquifer from the deeper (phreatic) zone. One of the things this study shows is th at the contamination at Stauffer is really not moving anywhere. ItÂ’s pretty mu ch staying in place (Quioco, 2003).
76 In the second of three new reports, a geo-physical consultant to Stauffer Management Co. has concluded that most of the Stauffer Super-Fund toxic waste site is sinkhole-free and geologically stable. Therefore, the consultant conclude s, there is no reason that Stauffer shouldnÂ’t go ahead w ith a plan to pile up contaminated dirt on the property and cover the mounds with a wa tertight cap (Danielson, 2003). The EPA was poised to let Stauffer go ahead with the mound and cap plan until 2003. In 2003 the residents and the local, state and federal officials, including U.S. Rep. Mike Bilirakis, Republican-Tarpon Springs, co nvinced EPA officials to pause and study the risk of sinkholes and groundwater co ntamination. Since 2003 the Stauffer Corporation has spent $3-million on three new hydro-geologic studies, and got ideas and advice on the work from a variety of agen cies before starting (Danielson, 2003). The next section of the research will concen trate on the more insidious issue of soil contamination relative to the ci tizen component. Soils that ha ve been contaminated with toxic compounds are one of many avenues of oral and dermal introduction that humans and other biologic organisms can become exposed to. Soil Quality Concerns Another insidious aspect of environm ental pollution also occurred at the conclusion of a production batch. As the phos phate slag was cooled it was transported and sorted for use as road bed material or building pad materi al. The processed phosphate slag has a low grade radium-226 ra dioactive identity. Th ere are no tangible records as to the final resting place for the pho sphate slag waste materials. It has been hypothesized that the vast major ity of the phosphate slag was so ld as road bed material.
77 Had it been used as a home pad material lo w grade gaseous radium -226 could be another environmental risk to homeowne rs within the project area. Peter Hessling provided the following pr oduction details that yielded large amounts of phosphate slag and silica waste pr oducts following each production cycle: When the residual phosphate slag was sufficiently cooled it was loaded back into railroad gondola cars and it was transported 2,000 feet to the north were it was graded for size and texture in an open aggregate storage yard. The phosphate slag was mark eted as a roadbed construction material. The slag material was used extensively as the primary roadbed constituent in the greater Tarpon Springs area. The slag material is known to contain low levels of radium-226. It is possibl e that some of the slag material was used for home site development such as foundation pads (Hessling, 2006). It is possible that silica rich phosphate slag has been dispersed throughout the study area for home site slabs and for road bed material. No records can be located that provide the possible inventoried locations for the silica enriched slag material. Study area residents could be exposed to pervasiv e gaseous radon poisoni ng if the radium-226 containing slag was used as building slab fill material (Gibbs, Hessling, 2006). In 1994, the EPA was aware that the Supe r-Fund site contained high levels of arsenic, lead and radium-226, as well as other contaminants that are known to or suspected of causing lung cancer (Danielson, 2003). Steve Richardson who is an environmental health scientist with the Agency for Toxic Substances and Disease Registry (A TSDR) is of the opinion that the Stauffer Super-Fund site is a past public health hazard and it may be a future public health hazard because of the quantity of the contaminants that are still there in the soil (Rondeaux, 2003).
78 The soil contaminants include: asbestos, fluorine, radium-226, calcium silicate and potentially very large volumes of bur ied elemental phosphorus (Gibbs, Hessling, Ryburn, 2006). Soil borings were recently cond ucted in 2006 an atte mpt to locate and inject grout into toxic buried materials. During the exploratory drilling efforts a small portion of buried elemental phosphorus was ex posed to oxygen. Th e soil boring activity resulted in a spontaneous subter ranean fire that forced work crews to flee from the work area. Fire rescue crews arrived and dete rmined that the subterranean elemental phosphorus fire should be allowe d to burn itself out. The s ubterranean fire and large phosphorus pentoxide clouds that emerged from the soil provided more tangible evidence that elemental phosphorus is buried in relatively shallo w depths of soil at the 1994 Stauffer Super Fund site (Ryburn, 2006). The soils in the study area are contaminat ed with a collectio n of toxic compounds that are hazardous to humans and the plant a nd animal communities. The next section of the research will focus on the fauna and flor a community that has been exposed to the adverse environmental conditions in the project area that are directly associated with the production of elemental phosphorus. Biologic Flora/Fauna Community This section of the resear ch, related to research s ub-question #3, will concentrate on the adverse conditions that are relevant to the broader biologic community outside of the production worker and citizen groups. The flora and fauna in the project area were exposed to the nearly continuous dispersal of gasses, fumes a nd dusts that are associated with the production of elemental phosphorus. The emissions created by the production of
79 elemental phosphorous produced adverse air, water and soil quality conditions that had the opportunity to interact with the various biologic communities. Air Quality Issues It has been determined that gaseous disper sions of sulfur dioxide reached levels of up to 860ppb at ground level a nd high concentrations were common within the project area air basin. Within three miles of the production facility it wa s common for sulfur dioxide concentrations to reach 500-840ppb at ground level. Sulfur dioxide is able to combine with atmospheric moisture to create sulfuric acid gas that is corrosive to plant tissues (Gibbs, 2006). Sulfur dioxide can readily er ode the protective cuticular wa x of vascular plants. If the cuticle of a vascular plant is eroded it e xposes the vulnerable epidermis of the leaf and bark structure. Removal of the protective cuticular wax exposes fragile epidermis tissue and this results in unregulated loss of turgor pressure. Plants readily wilt and desiccate when the protective cuticular wax is removed. Damage or removal of the cuticle also exposes the subject plants to primary a nd secondary pathogenic/disease damage. Vascular plants without a protective cuticl e desiccated quickly a nd turn brown (Cuda, 2007). The previous paragraph helps to clarify the antagonis tic processes th at the native plant community and agricultural crops were exposed to during the production period of 1947-1981. Plants that are exposed to elemental phosphorus suspended particles can display numerous adverse reactions to toxic concen trations. Elemental phosphorus smoke can
80 induce spontaneous leaf drop/ abscission, floral abortion, de siccation, foliage chlorosis and leaf tip burn or browni ng (Van Vorris et al, 1987). It has been determined that fluorine levels in the coniferous plant community ranged from 300-500 parts per million as early as June of 1948. Coniferous trees and Citrus trees are severe ly damaged by air born fluorine concentrations of 400 parts per million or greater as was confirmed by the analytical findings paid for by the citizens in the study area in 1948 (Wilson, 2000). The native Pine (Pinus spp), Oak (Quercus spp) plant community and the agricultural Citrus (Citrus spp) plant community was severely damaged by the daily dispersal of fluorine gas. The Citrus trees within the study area we re virtually wiped out during the late 1940s and early 1950s. For the most part no citrus tree production returned to the research project area (Wilson, 2000). As early as January of 1948 area resident s were becoming aware of environmental degradation that appeared to coincide with the opening of the Victor Chemical Works elemental phosphorus production facility. The concerned citizens filed a formal nuisance suit complaint in 1948 against the Victor Chemical Works regarding gas and fume damages relative to plants and animals. The following excerpts, that are derived from the legal deposition, provide the earliest tangible evidence of adverse environmental conditions that had already been imposed on th e human and larger biologic community in the research project area: In June 1948, less than a year after the plantÂ’s opening, eight local residents and landowners filed a nuis ance suit (for gasses and fumes) in the Federal District Court for southern Florida, Tampa Division (II). The suit alleged that fumes and gasses from the operation were adversely impacting human health and plants, not only in the immediate area, but as
81 far as 8 miles away, and that noxious gasses and fumes escape there from smokestacks connected with the said plant and by other means and are carried by the prevailing winds over a ra dius of some four miles from the elemental phosphorus plant, that th e said gasses and fumes are highly deleterious to animal and plant life for the said distance, cause throat irritations and coughing by persons and animals breathing same and the death of young fowls, that said gas is especially harmful to teeth and causes decay and kills and de stroys plant life (Wilson, 2000). In a more directed deposition Bartley Mickler alleged that his personal property including trees, cattle and pigs were being injured by the ai r pollution that was emanating from the Victor Chemical Works plant. He stated in his deposition that sinc e the Victor plant opened he had lost livestock. He indicated th at he lost a lot of pi gs and about 100 head of cattle. Mickler also indicated that pine trees on his 5,000-acre property were affected by the plant. He indicat ed that in January or February of 1948, he noticed pine need les turning red and brow n and falling from the trees. His estimate was that at leas t half of the trees were adversely impacted. New growth would bud out and then die back without being replaced. Mickler also stated that was less forage grass and berries and that this had caused damage to quail and game birds. The grass normally comes out the first of the year. But just prior to the lawsuit; the grass has come out and then died, resulting in forage grass production being down by 40 percent. Mickler also stated that fumes and gasses from the plant settled on palmetto bushes on his property. Samples from palmettos and pine from across his pr operty were sent to th e state plant board for analysis. Mickler traced the damage based upon the way the smoke from the Victor traveled, at least 7 miles from the plant. He described the smoke looking like a hazy gas substance and you can see it settling for miles through the woods under th e tops of trees (Wilson, 2000). The deposition of Mr. Mickler clearly punctu ates the pervasive adverse effects of gaseous fluorine poisoning in the native flora. The native Slash Pine (Pinus elliottii ) and Longleaf Pine (Pinus palustris ) coniferous species are highly susceptible to fluorine toxicity. The evergreen character of conifer ous plants allows an extended period of time to absorb fluorine gas without a seasonal l eaf abscission event. Sulfur dioxide and
82 phosphorus pentoxide gasses are also caustic to leaf and bark cuticles. However, gaseous fluorine and associated fluoric acid is toxic and bio-accu mulates so that exposure is compounded by the persistent buildup of toxici ty in the plant tissue and the supporting soil profile. The precipitated fl uorine emissions are also stored in the soil and it is readily absorbed in an aqueous solution along with essential nutrients. In this way, toxic fluorine is imposed on the plant community by way of natural nutrient procurement processes. Organisms that consume the fluorine contaminat ed plant material are also poisoned as a result of pervasive bio-accumulation. (Cuda, 2007). The following quote taken during the Ja nuary 1948 hearing provides a tangible account as to the plant damages that oc curred on private lands following the commencement of elemental phosphorus production. S. E. MicklerÂ’s Deposition (B MicklerÂ’s father) stated: That he was concerned about fumes a nd dust prior to the construction of the Victor plant and met with Paul Cr ider who worked for Victor. Crider told Mickler that, Â“You need not worry about it Mickler, it will not happen here with our plant. Around January of 1948 approximately 300 people signed the petition about the same tim e Mickler indicated that he began noticing offensive odors and harmful effect s from the plant. He noted that he smelled the odors in Tarpon Springs, and as far away as 6 to 7 miles in the pastures. The gas has been so bad that in low spots when the atmosphere would bring it down it would be just like a fog. Mickler estimated that one-sixth of the trees on his property were affected. He carried samples of pine needles an d palmettos to a Tampa chemist who reported that some of the materials showed 300, 400, 500 parts per million of fluorine. Mickler further indicated that he helped Archie Clement, tarpon Springs city attorney gather materials that the city manager had sent the samples to the State Plant Board in Tallahassee. Representatives of the Forestry Division visited the Mi ckler property four or five times. Mickler recounted that, they said it ha d to be fumes or gas or something. They said it was not the w eather wet or dry (Wilson, 2000).
83 The depositionÂ’s reference to pine n eedle samples that contained 300, 400 and 500 parts per million of fluorine provides strong tangible evidence of chronic fluorine toxicity in a native Coniferous plant species Fluorine is highly toxic to nearly all vascular plants and it is especi ally toxic to conifers as th ey retain foliage throughout the dormant season and this allows a more continuo us absorption of fluorine gas. Fluorine concentrations accumulate in plants as there is no natural process for decontamination. Mr. MicklerÂ’s additional depositi on provides his field observations. Regarding observed damage to trees, Mickler said, Well, I came in to dinner in town (Tarpon Springs) a nd I never noticed anything. When I came back out, and just as I went to make the curve, as you run by the oil company and go back towards the plant, I noticed the leaves on the trees being red. I stopped my car and said to my self, Â‘darn there has been a fire here since I have been along.Â’ I stopped the car and looked and there wasnÂ’t no fire. I ob served the trees had been burned by something, I donÂ’t know what (Wilson, 2000). The necrosis resulting from fluorine result s in rapid desiccation of leaf tissue. The fluoric acid pollution compone nt also erodes the leaf cuticl e and this also accelerates foliage desiccation and browning. The Victor Chemical Works had also hire d the services of a preemptive expert witness named John Claypool in March of 1947. John ClaypoolÂ’s Deposition (for the Defense of the Victor Chemical Works) states that: Victor Chemical Works also submitted to the court the deposition of John Claypool, an expert witness, questioned only by VictorÂ’s attorneys. John Claypool was from West Hempstea d, Long Island, New York. He received a B.S. from DePauw Univer sity in Chicago, and took advanced and special courses in the College of Agriculture at Purdue University, Indiana, until 1912. He taught pre-vo cational and vocational agriculture and in 1916 went to Teachers College as a professor of agricultural
84 education. In 1920, he worked for a chemical manufacturing company and a copper smelting company in New York, taking over the investigation and experimentation of the effects of certain smokes or gasses and fumes. Over the next 30 years Claypool studied the effects of gasses and chemicals in eight stat es, including Florida (Wilson, 2000). Claypool first visited Tarpon Springs on Ma rch 1, 1947, while the elemental phosphorus plant was under construction. Regarding th e findings on this visit, he stated, Vegetation in that vicinity at the ti me was not in a good state of growth. There had been an early season of drought, followed by unseasonably cold weather. Some plants, notably the pi nes, showed a scorched appearance of needles in places. It was not univ ersal. There were dead trees in the vicinity, confined to the pine family. I also found some dead citrus trees in a small orchard near the Victor site In looking over plant life in Tarpon Springs, I covered, as closely as I c ould without trespass ing or attracting undue attention, within a radius of tw o miles in all directions (Wilson, 2000). Claypool estimated that five to ten percen t of the pines in th e project area were dead. He also said that he saw two men remove and replace d ead trees in a citrus grove. The workers explained that the trees had died of either root rot or crown rot and that the orchard had not been well fert ilized or sprayed (Wilson, 2000). Citrus trees in the st udy area were severely damaged following the commencement of elemental phosphorus produ ction (Wilson, 2000). The fluorine that is liberated from incinerated phosphate ore pr ovided a continuous source of fluorine intoxication. Fluorine toxicity in Florida agri culture appears to be directly related to the relative geographic proximity of phosphorus processing facilities. Citrus production tends to decline when ambient air quality fl uorine levels are elevated by the synthetic alteration of phosphate ore (McBride and Walker, 1958). Fluoride toxicity in citrus trees is caus ed exclusively by exposure to gaseous, airborne fluorides. Fluoride toxicity asso ciated with citrus species (Citrus spp) has only
85 been noted in Florida. Fluorid e damage to other plant specie s has been observed in other states. Fluoride toxic ity in Florida associated with ci trus has only been observed within close proximity to manufacturing facilities that discharge gase ous fluoride. The symptoms of fluoride toxicity in citrus ar e typically found in gr oves which are located geographically down wind relative to the pr evailing winds from the gaseous fluoride emission source. A diagnostic chlorosis (a bsence of chlorophyll) is linked to acute gaseous fluorine toxicity in citrus. In more advanced cases of fluorine toxicity a tip and edge burn of citrus tree leaves can occur. If citrus trees ar e exposed to fl uorine toxicity for an extended period of time it is common to see a gradual reduction in the size of the tree foliage. Grapefruit appear to be the most sensitive of the Citrus genus and Oranges appear to be the most tolerant to exposure to gaseous fluoride. The inter-vienal chlorosis resulting from fluorine toxicity closel y resembles damage caused by manganese deficiency. At this time, there are no remedies for fluorine toxicity in citrus. Location of citrus in an environment that is free of gaseous fluoride woul d represent the best management practice (McBride and Wander, 1958). After analysis of the deposition has been completed it appears that the Victor Chemical Works anticipated that there could be adverse consequences to the plant community resulting from elemental phospho rus production. The Victor Chemical Works pro-actively hired the consulting botan ist John Claypool to help assess the pre versus post production conditions of the surr ounding plant community. The next section provides John ClaypoolÂ’s observations during a sworn deposition hearing in June of 1948.
86 When asked about the appearance of th e areaÂ’s vegetation, John Claypool said, Vegetation, generally speaking, did not a ppear to be in a fine, flourishing condition at all, anywhere. I woul d not say that it was universally scorched in appearance. I did not tr espass to examine closely. From the roads, there were signs that there had been a fire at some time. I was not acquainted with the plant, I did no t know whether this was a seasonal thing, whether fire brought these c onditions about, but that was the condition of the scrub palmetto at the time. Pale green to yellow (Wilson, 2000). On February 18 and 23, 1948, John Cla ypool returned to Tarpon Springs in response to a request from Vi ctor, because of unrest among neighbors in close proximity of the production plant and the conditions of vegetation. With the production plant in full operation, Claypool surveyed the area for appr oximately 2.5 miles in all directions, and describes what he found on his trip: In February of 1948, there was some no ticeable discoloration of the tips of pine needles or foliage within a di stance of a half mile in generally southeast or east-southeast direction. There was, on the date of my arrival, which was the 18th, some loss of green color on the tips of pine foliage, which by the 23rd, upon my return, had become a definite browning of the tips. That appeared to extend almost to the location of some oil tanks along the Anclote River, which is less th an a half mile from the operating part of the plant. I continued my close up inspection by walking along the railroad tracks to the north and f ound no evidence of anything unusual to vegetation in that dire ction. There was no noticeable damage to the Flanagan and Turnpaw properties. Fo liage westerly or north westerly appeared to show no change since my vi sit a year before. Sunset Hills, the general condition of vegetation appeared to be better at that time than it had been the previous year (Wilson, 2000). Mr. Claypool is describing chronic fluorine toxicity in the indigenous coniferous forest Slash Pine (Pinus elliottii ) and Longleaf Pine (Pinus palustris ) in the study area. Coniferous trees do not drop foliage during the winter season and are more biologically active in the winter than most deciduous plant species. This particular characteristic allowed the Coniferous plant community to absorb fluorine in larger amounts during the
87 first three months of production at the Victor/Stauffer facil ity. It could be logically deduced that an evergreen plant community would assimilate fluorine more effectively than a deciduous plant community during the winter of 1947/1948. When asked, Well from your experience of more th an 30 years, did you form any opinion as to the cause of the discol oration of the pine needles of the foliage at Tarpon Springs John Claypool answered, In my opinion, it was caused by a gas or fumes. I believe it was probably from a fluoride compound (Wilson, 2000). After two exploratory forestry investiga tions Mr. Claypool was able to come to the conclusion and make the admission that it was most likely a fluoride compound that has damaged the local plant community. The resident Mr. Mickler observed a declin e in the health of the native plant community during his daily travels throughout the study area. Mr. Mickler makes the observation that the gaseous emissions are capab le of weakening the l eaf structure of Saw Palmetto (Serenoa repens ). The emissions (from the plant) looked like a fog, and from a distance an observer could not see through the mi xture. Trying to describe the emissions (from the plant) which impact the plants (trees and shrubs), Mickler went on to state, You can see it on oak and palmetto anywhere in the woods. It is a kind of dusty concern, although not much dust to it, either. It looks oily. For instance, on palmetto, when it first h its it, it will limber up and look like it has oil on it. It limbers up a leaf and kind of parches it (Wilson, 2000). The previous deposition statements by J ohn Claypool detail hi s field observations over an extended period of time. Even though he was hired by the Victor Chemical Company, he was able to asce rtain that fluorine emissions were the causal agent of necrosis in the flora community.
88 Another deposition was provided by Genevieve Flanagan who had complained that gasses and fumes became bothersome at he r trailer park in Janua ry of 1948. She said the following: We smelled it [the gasses], to begin with, and you could see it, and then many trees started dying. It killed a lot of them [tr ees and shrubs] and it is killing my pine and oak trees as well. All of the natural pines turned completely red, and two oak trees died within a week, the water oaks the leaves just burned; the others lost a lot of their leaves but some of the growth has come back; I donÂ’t know whet her they will live or not; and two of the large water oaks died within that week, and one large orange tree died. All of my palms; as soon as th ey put out a new leaf by the time they were out two or three w eeks they turned. The Plumosa Palms, I trimmed a lot of them, about two weeks, and just as fast as they put out the new growth they just turned again (Wilson, 2000). The Stauffer Chemical Corporation was c onsciously aware of the emission issues that adversely affected the pr oject area (Hessling, Gibbs, 2006). Joyce Gibbs stated: The manufacturing facility commonly c onducted two of three batch cycles per day during the night and evening hours. This served a two-fold purpose. This allowed the plant to benefit from the use off peak hourly rates when energy rates would be lo west. Night production helped to reduce production costs. Secondly, the nightly production of elemental phosphorus allowed the clouds of phosphorus pentoxide and sulfur dioxide gasses to go visually unnoticed by the surrounding public. Another issue that has gone rather unnoti ced is the fluorine toxicity issue. The burning of phosphate rock liberates signifi cant amounts of fluorine gas that is a natural com ponent of phosphate ore. Fluorine in the gaseous state or in solution is highly toxic to all plant species. The plants in the vicinity of the elemental phosphate production plant showed classic symptoms of fluorine toxicity. Plan t growth had not returned to normal levels even after the production facility had been closed for 26 years. This has left the site with a denuded and harsh appearance. My observations are that no recovery has occurred in the plant community since my observations began in 1975. I think the soils of the area are probably highly acidified from the effects of fluoric acid, phosphoric acid and sulfuric acid (Gibbs, 2006). Joyce Gibbs recalled another issue relativ e to gaseous fluorineÂ’s adverse impact:
89 I spoke to Stauffer operations staff and suggested to them on several occasions that they could reduce some of the dust dispersal if they were to plant several rows of trees around the production facility. Stauffer operations staff always met my sugges tion with approval. However, they never followed through on the tree pl anting suggestion. ItÂ’s my opinion that Stauffer was hesitant to plan t trees around the production facility since they were concerned the trees w ould have most likely died from the toxic fluorine emissions. I think Stau ffer was aware the trees would have done poorly or died and this was not the type of condition they wanted to display (Gibbs, 2006). Fluorine has also had very deleterious effects on the domesticated fauna community in the study area. A similar adverse condition to Pinellas CountyÂ’s was simultaneously occurring in Polk County, Flor ida where numerous phosphate processing plants had been constructed after World-War-II were also releasing damaging gasses and fumes. The following two paragraphs prov ide details from a former Polk County CattlemenÂ’s Association president relative to Po lk County, Florida agriculture that was in close proximity to a phosphate pr ocessing facility (Linton, 1970). Approximately seventy-miles to the east in Polk County, Florida approximately 150,000 acres of cattle production pasture were abandoned a nd 25,000 acres of citrus were adversely affected by phosphate pr ocessing plant emissions from 1953-1963. Between 1953 and 1960 the cattle population of Polk County was diminished by approximately 30,000 head (Linton, 1970). The Polk County incident of both cattle and citrus producti on losses are very similar relative to geographic location to an elemental phosphorus production facility. The larger geographic size of the Polk C ounty agricultural industry dwarfs Pinellas County. The 25,000 acre loss of citrus production in Polk County resulting from fluorine
90 toxicity would represent appr oximately twice the geographic area of Pinellas CountyÂ’s peak production of 13,500-acres of citrus in 1950 (Linton, 1970). The Polk County cattle decline resulting from fluorosis closely rese mbles the smaller Pinellas County study area were approximately 5,000 acres of pastur e land was poisoned w ith fluorine derived compounds (Wilson, 2000 and Linton, 1970). Fluorosis in cattle that have grazed on contaminated land has now become clinically well understood. The following pa ragraph provides tech nical data from a veterinarianÂ’s manual: Skeletal fluorsis generally results in the accelerated resorption of bone structure. Metabolically active ri b, mandible and long bones are most adversely affected by the development of chronic fluorsis. The actively growing bones of young animals are greatly affected. Cattle with chronic fluorosis are lame, and feeding and water uptake and weight gain are decreased. In advanced stages of fluorosis cattle may move around on their knees due to painful spurs and bridging in joints. When the bone tissue has become saturated with fluorine the soft tissue becomes impregnated with fluorine spill over. Th e next stage is for the spill over to contaminate the blood supply and this is followed by extreme listlessness and suppression of appetit e (Merck & Company, 2006). Polk County rancher Mr. Cridder noticed in 1953 that ther e was a significant downturn in our cattleÂ’s health and vigor. The cattle were no t able to put on bulk weight as they usually are able to. As the decl ine continued our cattle were actually loosing weight. Following the observed downturn in the cattleÂ’s health our cattle were afforded the highest quality pastures we had and used all methods we were aware of in an attempt to restore the health of our cattle. We incorporated supplemental dermal nutrient drenches and de-wormed the ca ttle in hopes it would rest ore vigor but this did not improve the vitality of the cat tle. The cattle gradually lost their teeth and became gaunt and their legs were noticeably deformed and the cattle limped and staggered. In 1953 the
91 rate of calf production dropped and if a cow ha d a calf it was gaunt or a stillborn. After our efforts to improve the health of the cattle failed the veterinarians diagnosed the adverse condition as massive fl uoride poisoning (Linton, 1970). The source of the fluoride poisoning within Polk County, Florida was traced back to the gasses and dust dispersed by prevailing winds from the smokestacks of phosphorus processing plants in proximity to citrus groves and pasture lands of Polk County, Florida (Linton, 1970). As mentioned above gaseous fluor ine poisoning can produce adverse environmental conditions in domesti cated animals on a large scale. The most important problem concer ning damage to animals by air pollution is, no doubt, the poisoning of domesticated animals caused by fluorine in smoke, gas, or dust from va rious industries; i ndustrial fluorosis in livestock is today a disorder well known by veterinarians in all industrialized countries (Connet, 2003). Fluorides derived from processed phos phorus ore are liberated into the atmosphere as hydrogen fluoride (a gaseous stat e) or as silicon te trafluoride (a solid particle). The fluorine can be absorbed or it can accumulate on or may be metabolized within vegetation surfaces dow nwind of the source point. If the fluorine contaminated vegetation is consumed by livestock it can cau se severe adverse he alth conditions, in particular to cattle. Over ninety five percent of cons umed fluorides become an amalgamation within the bone matrix of the consuming animal. Fluorine that is not absorbed into the bone matrix is metabolized a nd excreted in either urine or feces. The teeth of cattle are perm anently damaged by fluorine if intoxication occurs within the first 36-months of birth. Severe intoxication with fluorine can cause cattle to develop rapid tooth erosion/destruction, sti ff joints and profound lameness. Lameness of cattle induced by fluorine intoxication is caused by brittle a bnormal bone tissue formations that replace
92 normal bone tissue in the metatarsals and me tacarpals of the bovine hoof. The lameness and associated pain of walking and standing reduces the time cattle can graze which can lead to lower milk yield, re duced body weight and possible starvation (Fischer and Prival, 1973). The following excerpt further expands on th e toxic nature of fluorine relative to domesticated livestock: Poisoning occurs where the fluorine c ontent of dry grass exceeds 250ppm. Prior to death, the poisoning causes le sions in the nose, mouth and hair around the mouth tends to fall out (Gregory, 1996). The danger of fluorine in the food chain has not been limited to just Pinellas County, Florida as can be seen in the following paragraph as well. The Canadian Broadcasting Corporation (CBC) has used the word PandoraÂ’s Box to describe the insidious pollution sources that are derived from the phosphate industry. The CBC states that the phosphate processing did bring enterprise to the agricultural community. However, the phosphate processi ng industry brought se vere environmental damage into the agricultural community. The CBC describes the adverse impact of phosphate processing at one specific site were farmers first noticed that pepper plants and the pepper fruit were burned and dwarfed and gas and fumes damaged nearly everything that grew. A substance in the air was dama ging the agricultural crops. This specific adverse environmental case was first noted in 1961 and then again in 1962 near Dunville, Ontario. Grain production was cut by 50%. After arduous investigations it was determined that the adverse agent was fluorine concentrations in the pasture grass and dry hay. The cattle were becoming disabled with swollen legs, loss of teeth, painful mouths and hooves such that th e cattle simply lost the ability to stand and would lie down and
93 die. The cause of the loss of hundreds of ca ttle in Dunville, Onta rio was from chronic fluorine poisoning of the air and pasture grasses (Connet, May 2003). In 1969 an article in the Good Housekeepi ng magazine featured an article that described the demise of cattle in Garrison, Montana resulting from chronic fluorosis: The fluorine induced blight afflicted th e cattle also. Some of the cattle lay in the pasture, barely able to move Others limped and staggered on swollen legs, or painfully sank down and tried to graze on their knees. After being ingested day after day, th e fluorine contaminated pasture had caused tooth and bone disease in the cattl e, so that they could not tolerate the anguish of standing or walkin g. Even eating or drinking was an agony. Their ultimate fate was dehydration, starvation and death (Connett, 2003). The previous paragraph provides a tangibl e example as to the pervasive adverse impacts that can be generated from the synt hetic alteration of be nign Apatite/Phosphate ore. The high temperature of elementa l phosphorus production liberates many toxic synergistic compounds that are injurious to mammals and plant communities. When the Victor Chemical Works plant came on line in 1947 it had two state of the art carbon-arc furnaces that could achieve operational temp eratures of 1,650 degrees C/3,000 degrees F. The 1,650 degrees C/3,000 degree F furnace temperature was sufficient to melt phosphate ore and produce up to six large batches of elemental phosphorus on a daily basis. The elemental phosphorus by product emissions in cluded air suspensions of: toxic fluorine, sulfur dioxide and phosphorus pentoxide. Each of the two furnaces had an operational capacity of approximately 458 cubic meters/ 500 cubic yards of raw phosphate ore. The carbon-arc furnace dimensions were approximate ly 7.6 meters/25 feet in diameter and 8.55 meters/28 feet in height. The vast qua ntities of processed phosphate ore at the
94 Victor/Stauffer facility assured a nearly constant cloud of synthetic compounds would exist in northwest Pinellas County (Gibbs, 2006). Soil Quality Issues The other aspect of physical geography that imposes a unique risk in the study area is the presence of mantled karst topogr aphy. The Stauffer Ma nagement Corporation has spent significant capital in an attempt to determine if the karst environment is active or in a state of inactivity (p aleo-karst). It has been de termined by several geo-physical tests that active karst processe s are currently absent on 90% of the 130-acre land parcel. A mound and cap remediation proposal ha s been offered by the EPA based on the conclusion that subsidence activit y is not active at this time. When and if a subterranean subsidence event will occur is rather difficult to predict. Soil bori ngs of up to 100Â’ in depth have been the basis fo r the conclusion that there is a low risk of sinkhole development in the project area (Wilson, 2000). Another aspect of physical geography that imposes addi tional risk in the project area is the soil characteristics. The soils in the project area are derived primarily from urbanized Astatula fine sand. This particular aridisol is of s iliclastic origin and is a soil which exhibits very low cohesive characterist ics and very low organic content. The low cohesive forces of this soil and the relative low ground water elevati ons coupled with low organic content create a lo w fertility and highly drought y and unstable condition for native plant colonization. The damage to the native plant community resulting from fluorine toxicity left the project area devoid of plant cover and exposed to colonization from opportunistic exotic and invasive plan t species. When opportunistic noxious plant communities become established they can impose antagonist ic/alleleopathologic
95 influences on competing plant species. Th e very low fertility level and droughty character of urbanized Astatu la fine sand makes anthropogeni c restoration of native plant communities problematic. The Victor/Stauffe r siteÂ’s contamination scenario also affected local plant communities. It is well understood that fl uorine is not mobile in soils and toxic levels can exist within the soil horizon for extended peri ods of time (Meister 1991). However a scattering of residents within the project area have been successful in growing Citrus trees. Damage to Pine and Oak trees resul ting from fluorine toxi city has allowed for opportunistic colonization from exotic and invasive plant species. The project area currently supports a la rge population of Braz ilian Pepper (Schinus terebinthifolius ) which has been able to exploit the low fertility of the disturbed Entisols in the study area. The study was not able to determine if Brazilian Pepper plants are tolerant of fluorine contaminated soils. The existing native tree and shrub vegetative character of the study area is very spar se and supports very few recruiting plants. If Brazilian Pepper are as part of the shrub and tree plant community the ar eal coverage of tree a nd shrub plant species would be below 20%. The Stauffer Manageme nt Corporation has recently conducted a Brazilian Pepper removal program on its 130acre parcel in 2000 as an attempt to minimize the seed source of this highly invasi ve plant species in the study area. Research regarding fluorine persistence in Entisol soils is not well understood. The project area would represent an excellent oppor tunity to conduct future fl uorine soil residue research in the context of Florida coastal Entisols. Another issue of concern within the study area is the possible effect of unintended anthropogenic acidification of the native soil s. Where the soils in the project area
96 chemically altered by the emissions of fluorine, phosphorus pentoxide, phosphine and sulfur dioxide gasses? Phosphor us derivative aerosols have th e ability to increase acidity in soils depending on the buffering capacity of a specific soil (Van Vorris et al, 1987). When soil pH is reduced by an acidifica tion agent it is possible that essential macro and micro elements essential to plan t growth can become bound to the soil and become unavailable for assimilation. When soil pH values fall below (5.4) toxic aluminum can be liberated from siliclastic pare nt soils. It is therefore possible that plant damage in the project area that had been observed over the past 59-years could be in response to soil acidification a nd toxic aluminum liberation. ATSDR ombudsman Ronnie Wilson is of th e opinion that, the Stauffer SuperFund site has fallen through the cracks. The assessment of the public health threat was rushed and because of this it was very incomp lete and virtually useless for his agency to act on (Rondeaux, 2003). The Stauffer Super-Fund site has been under close scrutiny by the EPA since 1994 when politicians began to champion the cause of the Tarpon Springs community. During this period various studies to a ssess risk have been conducted by both governmental and by contracted consulting serv ices who have been hired by the Stauffer Corporation. As of this time, no single risk /hazard study has been de clared conclusive by the EPA (Ryburn, 2006). The 2003 Agency for T oxic Substances and Disease Registry (ATSDR) health study conclude d that the workers were face d with working in unhealthy working conditions with little or no protection from contamination.
97 Chapter Six Summary and Conclusions This thesis attempted to determine the extent of adverse environmental impacts that occurred in Pinellas County as a resu lt of elemental phosphorus production. The research gathered and assessed the combined resources of historical documents, technical bulletins and institutiona l knowledge to create a base data that upon analysis revealed new knowledge about the complex cultural and environmental issues associated with elemental phosphorus production in Pinellas Co unty, Florida. This analysis allowed the sub-research questions and the over-archi ng research question, to be answered. The research project was framed within sc ope of three sub-research questions and the one over-arching res earch question. The s ub-research questions that framed the research are: Â“What are the adverse impacts im posed on employees relative to air quality, water quality and other forms of exposure in the study area? What are the adverse environmental impacts imposed on the citizens relative to air quality, water quality and other forms of exposure in the study area? What are the adverse environmental impacts imposed on the non-human organisms relative to air quality, water quality and other forms of exposure in the study ar ea?Â” The over-arch ing research questi on that framed the research was: Â“What are the adverse envir onmental impacts resulting from the production of elemental phosphorus in Pinellas County, Florida?Â”
98 Regarding the first sub-research question, based on the historical, technical and interview research findings, employees at the Victor/Stauffer facility were exposed to a constant source of toxic gas and dust emi ssions. The gas and dust emissions were the vehicle that conveyed numerous toxic synt hetic materials into the respiratory and digestive system of the workers. The hi gh temperature processing of phosphate ore, silica and coke resulted in the liberation of gaseous/aerosol clouds containing: asbestos, fluorine, phosphorus pentoxide, phosphine, radi um-226 and silica. Independently each of these toxic components represen ted a significant exposure heal th risk to the workers. When workers are exposed to the agglomera tion of synthetic com pounds listed above, a synergistic complex of toxic agents is created. The complex of toxic agents were pervasive and as such the production workers inhaled, absorbed and ingested the gasses, aerosols and associated precipita tes. The research found that the workers were frequently burned both chemically and physically. The re search determined that the workers were exposed to air borne asbestos that can induce asbestosis. The research revealed that employees were exposed to fluorine gas that can result in chronic fluorosis. The research also determined that production facility workers were also e xposed to phosphorus pentoxide gas that in sufficient concentra tions can burn and ulcerate lung tissue. The dental facilities located within the el emental phosphorus production facility provide tangible evidence that the Stauffer Chemical Co rporation was fully aw are of dental risk associated with working in an enhanced phosphorus environment. Oral diseases including Â“Phossy-jawÂ” were one of many possible adve rse environmental impacts imposed on the employees that worked in cl ose proximity to the enhanced phosphate and fluorine environment. No written records were located in this study th at directly link the
99 in-house dental facility to th e existence of chronic oral disease associated with the production of elemental phosphorus at the Stauffer production facility. It is highly likely that oral disease issues asso ciated with the work environment were handled within the company sanctioned dental facility. This particular issue may never be fully clarified as there does not appear to be an avenue to investigate past dental records. The second sub-research question asked: Â“What are the adverse environmental impacts imposed on citizens relative to air quality, water quality and other forms of exposure in the study area?Â” Based on the hi storical, technical a nd interview research findings, local citizens within the study area we re exposed to persistent clouds of toxic gasses and dust emissions. Unlike workers who had 40-hour per week work exposures, the resident citizens had the potential fo r up to 168-hours of exposure time per week. The citizens in the study area were exposed to nearly all of the adve rse impacts that were associated with the workers. The citizen s were only excluded from the physical burn adverse condition that the workers were exposed to. However, due to the vast quantities of gaseous and aerosol emissions, the citizens were frequently breathing and living in the same adverse air quality that the workers were exposed to. All citizens in the study area were exposed to adverse health risks associated with living in an ar ea that was permeated with: asbestos dust, fluorine gas, phosphorus pentoxide gas, sulfur dioxide gas, radium226 and silica dust. Citizens also suffered fr om contaminated private wells that were fouled by fluoric acid, phosphor ic acid, radium-226 sulfuric acid. Citizens may have relied unknowingly on contaminated private we ll water resources for up to 47-years. The third sub-research question asked, Â“What are the adverse environmental impacts imposed on the non-human organisms relative to air quality, water quality and
100 other forms of exposure in the study area? Â” Based on the histor ical, technical and interview research findings the biologic co mmunity within the study area was also adversely impacted by the pollutant constituents of the Victor/Stauffer elemental phosphorus production facility. Less than th ree months following commencement of production the local residents were noticing a rapid decline in the health of the plant and animal communities. Gaseous fluorine intoxi cation in the project area produced highly adverse growing conditions for the large citrus industry of northwest Pinellas County. The well drained Astatula soil (Entisols) of northwest Pinellas County provided Citrus growers with manageable moisture conditi ons to should have produced high quality Citrus trees. The fluorine gas emissions resu lted in reduced production in most Citrus species. Grapefruit were by far the most vulnera ble of the Citrus genus in the study area. Gaseous fluorine levels in the 300ppm-400ppm range can result in the persistent defoliation of Citrus (Citrus spp.) and Pine (Pinus spp) trees. Chronic defoliation events eventually deplete a vascular plantÂ’s car bohydrate reserves and therefore impose phyto metabolic decline or necrosis. The historical documents revealed that the citizens were qualitatively and quantitatively aware of the adverse envir onmental impacts that the Victor/Stauffer production facility had imposed within the stud y area. The persistent emissions from the Victor/Stauffer facility over a 34-year period had destroye d the livestock, citrus and much of the native plant community. Fl uorine intoxication was a bioaccumulation hazard within the project study area during the time of active elemental phosphorus production. Ruminating livestock consumed the improved pasture grasses Bahia grass (Paspalum notatum ) in the project area over an extended period of time. The daily
101 consumption of fluorine contaminated forage resulted in highly el evated levels of fluorine in the bone structure matrix of all an imals feeding within the local trophic web. Fluorine preferentially replaces calcium in all bo ney structures. The boney structures that exhibit the greatest wear and te ar such as knee and ankle structures are most quickly replaced. Therefore, weight bearing bones such as leg bone s and jaw bones were predisposed to fracture and structural abnorma lities. During the years of operation of the elemental phosphorus production facility all local livestock producti on would have been at risk from systematic fluorosis intoxicati on in large part due to prevailing winds and the pervasive compounding effect of bioaccumu lation. Bovine calves would have been at the greatest risk as feeding from their moth er would have resulted in several magnitudes of toxic fluorine bioaccumulation. Bone stru ctures of mammals became malformed from chronic fluorosis and disease symptoms are manifested in chronic oral and podiatry diseases that gradually killed livestock by incapacitation and starvation. As of this time the native plant community has not recovered to levels of density or vigor that can be observed outside of the study area. There ha s been no recovery to the agricultural component in the study over the past 26-ye ars since production at the facility was suspended. At this time, the research study area supports only a stressed ruderal plant community. The larger over-arching research ques tion asked: Â“What are the adverse environmental impacts resulting from the production of elemental phosphorus in Pinellas County, Florida?Â” Based on the collective findi ngs of the sub-research questions it can be qualitatively and quantitatively determin ed that adverse environmental impacts resulting from the production of elementa l phosphorus were diverse and pervasive
102 throughout the study area. The research study was able to determine that workers and citizens were exposed to quantifiable levels of phosphorous pentoxide gas, sulfur dioxide gas and qualifiable levels of fluorine gas, asbestos, radium -226 and silica. The study was able to determine that the non-human (f lora-fauna) communities were exposed to quantifiable levels of fluorine and qualifiable levels of asbestos, phosphorus pentoxide, radium226, sulfur dioxide and silica. The study was able to determine that elemental phosphorus, fluoric acid, phosp horic acid, radium-226, a nd sulfuric acid have contaminated the surficial and Floridan water resource within the study area. As a result of the extensive ground water contamination all of the private wells within 4-miles of the production facility have been abandoned by the Pinellas County Health Department as of 1994. It can be concluded that the agricultu ral industry in northw est Pinellas County was adversely impacted by the deleterious eff ects of elemental phosphorus production. The cattle and citrus components were significantly damaged by th e antagonistic effect of the fluorine gas and vapors that settled over the project area. The symptoms of fluorine toxicity are perhaps the most glaring adverse environmental impact that influenced the project area in the largest geographic context. It may never be known how many oral diseases resulted from the wind driven di spersion of fluorine gas throughout the study area. Visual observations provided by numerous environm ental officials since 1981 has helped to confirm that native plant coloni zation in the project area has been greatly inhibited. It could be deduced that the re tarded native plant community colonization is the result of fluorine contamination or exces sive anthropogenic acidification of the soils. The influence of the elemental phosphorus production facility did create adverse conditions for the geologic and biologic comm unities. The humans, livestock, wildlife,
103 soils and surficial water resource were adversely impacted by the numerous toxic synthetic compounds that were created from ph osphate ore processing. It is much more difficult to ascertain the continuing risks that will continue to persist at the research project site. It has been determined in a previous study at Eagle Flats, Alaska that elemental phosphorus has a half -life of up to 10,000 years when it is held in an oxygen deprived environment. The proposed mound and capping method of remediation that the EPA has sanctioned for the Victor/Stauffer elemental phosphorus production facility will attempt to compartmentalize the buried elemental phos phorus waste materials within a Portland cement vault. The mound and capping remedia tion project will actually perpetuate the period of time that elemental phosphorus will remain within the study area as a contaminant. The persistence of anaerobic elemental phosphorus is roughly equal to the current length of the geologic Holocene Pe riod. It is therefore possible that the hermitically contained elemental phosphorus in the Northwest Pinellas County study area could persist into the next climatic cycle following the Holocene Period. The study was unable to determine if water resources within the elemental phosphorus production facility were contaminate d. If public health records confirm that no municipal water sources were provided to the Victor/Stauffer production facility; it could be deduced that workers would have had access only to a private water well resource that would have been another sour ce of adverse environmental impact to them. Interviews with past employees and supporting exploratory ground penetrating radar (GPR) has lead the EPA to conclude that up to 600 55 -gallon drums of elemental phosphorus has been buried in the study area. Em ployees of Victor/Stauffer indicate that
104 it was common practice to bury the waste barrel s below the water tabl e so that no oxygen could reach the elemental phosphor us. The citizens are concerned as to the fate of the barrels during extended drought. Extended dr ought could result in lowered groundwater and this could expose the elemental phosphorus to small amounts of oxygen that might be present in the soil profile. Based on the 1972 Pinellas County Soil Surv ey the soils in the study area support a water table th at can rise to w ithin 40Â” of the soil surfa ce during extended wet periods and can drop to grea ter than 60Â” during periods of extended dryness. Extended dry periods could result in a lowered vadose water table which could allow oxygen to permeate through the soil profile to the buried dr ums. The result of such a low water table scenario could result in the subterranean combustion of vast quantities of elemental phosphorus (Ryburn, 2006). The current the EPA inventory of the Stauffer Chemical EPA Super-Fund site indicates there are three majo r hot-spots were buried contamination is concentrated. These areas include: 1) the electric-arc furnace zone, 2) the elemental phosphorus clarifier zone, 3) the elemental phosphorus barrel dumping zone (EPA, Stauffer Assessment, 2003). Charley Ryburn provides the following statement: The EPA currently anticipates consolidating the three toxic burial Â“hot-spotÂ” areas as much as is practical. The consolidation procedure will be followed with the addition of clean fill soil that will cover the hot-spot areas with more compacted overburden. This procedure will be done in order to build a more effective oxygen depriving soil buffer. The final step will be to br ing a drilling rig on site in or der to bore numerous exploratory grout injection holes into the buried hazardous ma terials. The soil grout injection will be
105 an attempt to structurally segregate the h azardous materials from adjacent soils and groundwater sources. It is currently believed that at least 600 55-gallon drums of elemental phosphorus remain buried on-site (Ryburn, 2006). The long term adverse environmental im pacts in the study area continue to include the toxic effects to ground water from fluorine, elem ental phosphorus, lead, radium-226, silica, su lfuric acid and phosphoric acid contamination. Another ongoing adverse environmental impact would include the issue of soil contamination. Residents who plant and consume food sources from ve getable or fruit bearing plants could be ingesting fluorine contaminants. It is in this context that the long-term residents are placed in a double jeopardy scenario. The re sidents in the study area were adversely impacted during the producti on years of 1947-1981 and yet in 2007 the insidious risk continues to persist as there are no plans to remediate or monitor the soil component. The full magnitude of adverse environmen tal impacts created by the production of elemental phosphorus in Pinellas C ounty may never be fully understood. The research project has contributed an additional body of evidence as to the pervasiveness and synergistic adverse environm ental impacts that occur as a direct and indirect result of elemental phosphorus productio n. The research has provided additional evidence that native and agricultural plant communities have been damaged within the project area as a direct result of elemental phosphorus production. Th e research clarifies that observable damage to the native and ag ricultural plant community occurred within 90-days of operational commencement and ha s remained evident for a period of 26-years following the closure of the production faci lity. The study has concluded that the
106 dispersion of fluorine gas has killed and continue s to curtail native plant species colonization in the project area for a period of 60-years.

108 Future Research The research conducted on this project provides the opportunity for further exploration of the numerous aspects of adve rse environmental impacts within the study area. Future research opportunities could include the following questions: 1). What are the long term adverse effect s of soil borne fluorine on native plant communities? 2). What are the effects of 34-years of anthropogenic acidification of Entisols and the affect on the associated plant communities? 3) Does the introduction of anthropogeni c soil acidifying compounds accelerate normal dissolution processes in Flor idaÂ’s mantled Karst topography? 4). Do some exotic plants such as Brazilian Pepper (Schinus teribinthifolius ) have the ability to tolerate and assimilate soil borne fluorine. If so, could tolerant plant species be used as fluorine remediation trap plants? 5). Can pumped concrete grout meet the intent of an air tight containment methodology for buried elemental phosphorus? Following the release of a third comprehe nsive geo-physical study/assessment of the Stauffer Super Fund site in June of 2003 it was determined there was sufficient clay confining layer to keep the siteÂ’s contamina tion from reaching the deeper aquifer Quioco, 2003). In this context, another future st udy could investigate if the mantled Karst topography of the study area is geologically isolated from the Floridan Aquifer.
109 The pervasive adverse environmental impacts associated with elemental phosphorus production of the past are now more fully comp rehended. The continuing adverse environmental impacts will require ad ditional and on-going analysis so that the voluminous buried contamination materials are effectively managed. The persistent halflife of buried anoxic elemental phosphorus only reinforces that the long-term adverse environmental influences resulting from the production of elemental phosphorus in northwest Pinellas County will continue unaba ted. Future research could also focus on tracking the effectiveness of the proposed entombment and burial remediation methods that are proposed for the abandoned production facility. The research continued to point to the possi bility of damage to the native soils in the project area. In this regard, future research could investigate the possible contamination of the native soil resource The introduction of the acidification compounds of fluoric acid, phosph oric acid and sulfuric acid into silicals tic soils can greatly reduce pH levels. When siliclastic so ils become highly acidic (5.4 or less) then can release toxic aluminum. If the native si liclastic soils were highly acidified it is possible that native plant recruitment coul d be significantly reduced due to secondary aluminum toxicity. Future studies could in vestigate if this probable soil toxicity phenomenon has taken place as a result of 34years of elemental phosphorus production in Pinellas County, Florida.

129 Appendix B: Elemental Phosphorus Technical Data Summary Elemental Phosphorus Production and Associated By-Products This section of the research is provided in order to help the reader to clarify the potential for adverse environmental contaminat ion within the project area. In order to assess the environmental risk that is presente d in the research it is important to first understand the chemical nature and propertie s of the contaminants in question. The toxicology framework provided in this sect ion will help to qualify the spatial and temporal adverse environmental impacts cr eated by the Victor/Stauffer facility. This section of the research provides the reader with a pr actical context of industrial production of elemental phosphorus that was conducted within the project area. It is important to note that elemental phosphorus production in Pi nellas County was a heavy industrial process; and as such, it was a large scale user of energy and raw materials. In addition to this the elementa l phosphorus production facility also generated large scale gaseous and dust emissions. Elemental phosphorus production in Pinellas County, Florida was conducted in two very larg e high heat electric ar c furnaces that were capable of chemically altering natural mine ral components. The elemental phosphorus production plant in Pinellas C ounty is not comparab le to the existin g super phosphate fertilizer production facilities in Florida. Industrial production of elemental phosphorus results in the high temperature liberation of numerous synthetic compounds that have
130 Appendix B: (Continued) only recently become understood. An elem ental phosphorus production facility must be framed within the context of an industrial facility that melts large quantities of impure phosphate ore in order to exploit the chemical constituents of raw phosphate ore. Chemical Summary of Elemental Phosphorus Elemental phosphorus is a synthetic com pound that is has numerous industrial applications. One industrial application of elem ental phosphorus is that it can be used as a constituent to create powerful phosphorus fe rtilizers. Phosphorus is one of the three primary or macro elements that are essentia l to sustain plant growth. Phosphorus is essential in plants to construct structural components of nucleic acids, phospholipids and adenosine triphosphate (ATP). Unfortuna tely, phosphorus is readily removed when plants are harvested and because of this many of the world's soils are chronically deficient in available phosphate Soils that are deficient in available phosphate cannot support the complex processes of cyclic phosp horylation that drives the internal plant energy cycle. As an agricu ltural benchmark the American agricultural industry has determined that 40 pounds of phosphorus is re quired from the soil profile for each 100 bushels of corn produced. Agriculturally exploited soil s must contain significant quantities of available phosphorus if an inde pendent farmer or corporate farmer is going to be competitive in the agri -business that exists in th e current world economy. The production of elemental phosphorus results in the creation of powerful phosphoric acids which are a product that can be readily an d economically transformed into soluble phosphorus for worldwide agricultu ral utilization. The large-s cale use of synthetically
131 Appendix B: (Continued) derived phosphate fertilizers has allowed for the large-s cale production of commodity food crops in regions of the world that w ould otherwise be sust ained by some other economy (Keeton, 1980). Elemental phosphorus manufacture is one of several technical steps in the chain of chemical manipulations that is needed in order to creat e large economical quantities of phosphoric acid. Phosphoric acid is the pr imary nutrient constituent in high phosphate fertilizers that can effectively fortify low na tural phosphorus levels in soil. In order to create the primary constituents for phosphate fe rtilizers; it was learned that large scale (scale of economy) manufacturi ng of elemental phosphorus was the most cost effective means to produce the building blocks of high phosphorus fertilizers. The high temperature reduction of raw phosphate ore has become one of the economical sources of soluble phosphorus for the world wide agri cultural industry (Far m Chemicals Handbook, 1991). Elemental phosphorus products are highly diverse and have unique chemical properties that have been utilized to kill and maim during periods of warfare. But, conversely synthetic elemental phosphorus produc ts also have the ability to fortify nutrient poor soils and this he lps to feed the every burgeoning world population that has become reliant on agri-science and the green revolution. Chemical Indentity and Properties Elemental phosphorus (P4) can not be derived from any natural source s or resources as it is the product of anthropogenic creation. La rge amounts of energy must be expended in
132 Appendix B: (Continued) order to synthesize elemental phosphorus to an industrial technical grade. Elemental phosphorus can be created by melting and reduction of raw phosphate ore, silica and coke in an electric furnace that can exceed temperatures of ( 1,648 degrees C or 3,000 degrees F). The reductive high heat process liberates elemental phosphorus gasses that are highly reactive in the presence of oxygen. In order to control th e oxidation process elemental phosphorus is contained in an anoxic envi ronment. Under i ndustrial production conditions elemental phosphorus is usually he ld under a thick blanket of stagnant water that acts as an oxygen barrier. When elemental phosphorus is held under anoxic conditions it exists as a nearly transparen t pellet shaped/crystalline white waxy solid material. The individual pa rticles of elemental phosphorus look similar to small offcolored pearls. When technical grade (99.8% pure) elemental phosphorus is held under controlled laboratory conditions it retains a chunky morphology and is yellowish white in color. Elemental phosphorus can not be diss olved in water. Th e specific gravity of elemental phosphorus is 1.82 and this quality a llows it to sink to the bottom of lakes, streams and holding ponds wh ere it can remain in an unoxidized stable state for indefinite periods of time. Elemental phos phorus has a boiling point of 280 degrees C at standard barometric pressure. The melti ng point of elemental phosphorus is 44.1 degrees C or 136.98 degrees F (The Condens ed Chemical Dictionary, 1981). It is believed that the German alchemist Hennig Brand was the first person to specifically identify elemental phosphorus in 1674. Brand's original synthesis of elemental phosphorus was produced from crude laboratory precipitations derived from animal urine(s) in 1669. It is believed that precipitations of bovine urine were used to
133 Appendix B: (Continued) create the original batch of elemental phosphorus (Webster's New World Dictionary of Science, 1998). Elemental Phosphorus Constituents The constituents of natural forms phosphor us can be derived from raw phosphate rock such as impure Ca3(PO4)2], in Apatite or [Ca5(PO4)3F]. The natural forms of phosphorus are essentially derive d from biogenic sources. The biogenic or natural sources of phosphate are generally low in the total content of available phosphorus. The most potent biogenic source of phosphorus is known as raw bone meal. Phosphorus sources such as bone meal were the staple of agriculture prio r to the creation of phosphate containing synthetic fe rtilizers. The raw bone meal of well nourished bovine livestock can yield as much as a (22%) dr y weight volume of available phosphorus. However, in contemporary agriculture the us e of raw bone meal has become a public hygiene problematic. The recent outbreaks of Mad Cow Disease in Europe and Canada has raised concern with regard to public health and because of this the use of slaughtered livestock bone material has been greatly cu rtailed The industrial and food chain hygiene concern has resulted in most sources of ra w livestock bone meal and steamed bone meal to be pulled from the shelves of agricultural commodity market sources in order to help assure the safety of the public. When co mpared to natural so urces of phosphate elemental phosphorus is a very high-density fo rm of phosphorus. The industrial standard technical grade for elemental phosphorus is a (99.8%) minimum purity by dry weight. The highest grades of elemental phosphorus can exceed (99.8%) purity and the technical
134 Appendix B: (Continued) grades that exceed (99.8%) purity are used for integrated circuitry and semi-conductor components (The Condensed Chemical Dictionary, 1981). Elemental phosphorus is an anthropogenic synthetic co mpound and as such it has unusual chemical characteristics that make it potentially dangerous to the uninformed public. The highly reactive nature of elemental phosphorus creates significant production, storage and handling issues that are not encoun tered when working with naturally occurring phosphoric compounds. Elemental phosphorus is very reactive in the presence of atmospheric gasses found within the lower levels of the troposphe re. Because elemental phosphorus is a very unstable and potentially oxidative in atmosphe ric gasses, it must be stored and shipped under very controlled anoxic conditions in order to safeguard against spontaneous ignition and fire. Safe st orage and shipping conditions of elemental phosphorus must provide air tight segreg ation from all oxidizing agents especially atmospheric oxygen. Elemental phosphorus spontaneously burns wh en exposed to the air (atmosphere). Elemental phosphorus is an acid-forming elemental material that readily combines with oxygen to create the oxide phosphorus pentox ide and phosphoric acid (P2O5). The phosphoric acid (P2O5) will readily combine w ith atmospheric water or ground water to create orthophosphoric acid (H3PO4). The acidic r eaction created by combining elemental phosphorus and water can have adverse effects on groundwater chemistry (Farm Chemical Handbook, 1991).
135 Appendix B: (Continued) Industrial Applications Elemental phosphorus is used in the cr eation of carbonated dr inks and numerous cleaning compounds. The computer industry utilizes large quant ities of elemental phosphorus in the production of semi-conductors and integrated circuitry. Elemental phosphorus continues to be used in large scal e applications by the military industry as an incendiary agent or as an explosion igniter for munitions. Elemental phosphorus is commonly found as a constituent in hand grenad es, mortar and arti llery round where it functions as an initiator. Elemental phosphor us has been the mainstay component in incendiary bombs since 1862 and smoke bombs since World war-I. When elemental phosphorus is discharged in the field it w ill burn under normal atmospheric conditions at 400 degrees C or 752 degrees F. The 752 degree F temperature is sufficient to weaken the structural integrity of poured concrete. The high burning temperat ure can rapidly heat combustible materials and this quality is exploited as an incendiary material. When exposed to atmospheric conditions elementa l phosphorus ignites s pontaneously and is rapidly oxidized into a thick cloud of phosphorus pentoxide gas and phosphine gas. The elemental phosphorus will continue to spont aneously oxidize until the phosphorus is consumed or when the oxygen source has been depleted. Oxidizing elemental phosphorus creates a brilliant yellow flame and produces a dense white smoke that contains toxic phosphorus pentoxide and fluorine. When humans are burned by elemental phosphorus medical staff will atte mpt to access the burned tissue under water and in darkened conditions so that the phosphorescent compound can be found and surgically removed from the vic tim (CBRNE-Incendiary Agents, 2002).
136 Appendix B: (Continued) The international military establishment ha s also created a very large demand for the explosive and incendiary qualities of wh ite phosphorus. The military application for elemental phosphorus was first employed as a strategic weapon during the American Civil War. During the early phases of the Am erican Civil War the Confederate States of America spy network attempted to incinerate several iconic New York City buildings by covertly placing wet phosphorus soaked sheets of paper in large bu ildings throughout the cultural capital of the North. As the inconspi cuous sheets of paper dr ied they burst into a spontaneous self-feeding 752 degree F fire source that resulted in several structural fires of targeted wooden buildings. This part icular use of elemental phosphorus was the leading edge of technology in the 1860s. (PBS Television, 2002) The incendiary qualities of elemental phos phorus were well unde rstood prior to the American Civil War. There have been numerous refinements and military exploitations of elemental phosphorus as a strategic weapon. The means to disperse elemental phosphorus on the battlefield was fully exploited during World War II when major cities such as: London, England; Coventry, England; Dresden, Germany and Tokyo, Japan were systematically burned from an aerial assault of elemental phosphorus containing incendiary bombs. In larger fi re bombing campaigns heavy explosives can dropped onto the burning phosphorus in order to add a turbulent mixt ure of oxygen to the existing fire storm to further enhance the pyro-genic quality of elemental phosphorus (Wikipedia, 2006). The Korean War saw the first large-s cale use of phosphorus bombs and napalm bombs used in conjunction. During the Vietnam War field campaign (1962-1975)
137 Appendix B: (Continued) elemental phosphorus and napalm were agai n used extensively to bomb Viet Cong military positions that were cloaked under dense tropical vegetation. In 2003, the United States military continued the use of elementa l phosphorus in artillery and mortar rounds to initiate the lethal explos ive charge. Military assaul ts made in open landscapes frequently require concealment behind a dens e smoke screen. The United States Army frequently utilizes elemental phosphorous sm oke generating munitions to mask military assaults under a cloak of white smoke (GlobalSecurity.org, 2006). Elemental phosphorus has been utilized as a component of high phosphorus fertilizers, rodenticides/rat poisons, insec ticides, smoke screens, incendiary devices and analytical chemistry. During war time elem ental phosphorus becomes a powerful tool of destruction and troop and ground forces disr uption. During World War II elemental phosphorus was used in the N azi fire bombing of London that destroyed large amounts of the urbanized city. During Worl d War II allied forces retali atory air strikes used massive quantities of white phosphorus incendiary bombs to incinerate large urban center targets such as Dresden, Germany and Tokyo, Japan. The following quotation expands on this point. The United States bombing strate gy of 1942-44 against Japan was expanded in a big way in March of 1945. This began with the fire bombing of Tokyo on March 9 and 1 0, 1945. The area of Tokyo selected was four miles by three miles, a zone with a civilian population density of 103,000 per square mile. A high con centration of incendiary (white phosphorus) bombs dropped from the huge U.S. B-29 Superfortresses ignited a series of fires, fanned by brisk winds, wh ich raged out of control within half an hour, the result of which was more than 15 square miles of Tokyo was burned out. About 100,000 men, women and children were killed and another 100,000 were made homeless. According to the U.S. Army Air Forces:
138 Appendix B: (Continued) No other air attack of the war (World War-II), either in Japan or Europe, was so destructive of life and property (Colhoum, 2001). During the Vietnam War, American military utilized a combination of napalm and white phosphorus bombs as anti personnel w eapons against Viet Cong ground troops in heavy jungles and open fields. The sec ond and third degree bur ns of human flesh inflicted by elemental phosphorus are not alwa ys lethal. A sub-le thal burn exposes the targeted human subject to secondary infection. An injured soldier es pecially those with severe chemical burns require tremendous amounts of intensive medical care. The medical demands of burned soldiers place a major strain on the advancing or occupying armed forces and this consumes large numbers of potential soldiers who are relegated to transporting burned soldiers to field hospi tals. Severe burns imparted by elemental phosphorus require very larg e amounts of blood material in order to support the transfusions that a burn victim will require if he or she is to likely to survive. Elemental phosphorus munitions are intended to burn or firebomb the opponents, in other words, to effectively produce widespread damage but not necessarily kill the enemy (Agency for the Toxic Substances and Disease Registry [ATSDR], 1997). Elemental Phosphorus Production Techniques At the present time large scale elemen tal phosphorus production can be created using either of two industrial methods. Th e industrial process that was utilized at the Victor/Stauffer production facility in Pine llas County, Florida and Garrison, Montana production facilities is known as the high temperature or process one method. The industrial preference since the 1980s is a process called the we t process or process two.
139 Appendix B: (Continued) The following section provides a brief descri ption of each process and the distinct differences of each. High temperature reduction of phosphate ore was the preferred method of producing elemental phosphorus until the 1970s when energy costs reduced its profitability. The industrial reduction of phosphate ore is accomplished by the blending of adjuvant coke, silica sand with phosphate ore in an oxyg en deprived high temperature (1,648 degrees C or 3,000 degrees F) electric arc furnace. The liberated phosphorus vapor product is driven off by hydraulic for ces and condensed under a barrier of water. A clarification process removes impur ities during the production phase. The Victor/Stauffer elemental phosphorus product ion facility utiliz ed only the high temperature reduction method. Elemental phosphor us can also be created by reaction of phosphate rock with sulfuric acid. The residual calcium sulfate product is removed utilizing a filtration process. The con centrated phosphoric acid product is removed utilizing an evaporation process. The sulf uric acid reaction pro cess is commonly known in the phosphate industry as the wet process. The more contemporary wet process is much less energy consumptive than the high temperature method. The more contemporary phosphate industry utilizes the wet process in order to reduce operational costs (The Condensed Chemical Dictionary, 1981). Elemental phosphorus is highly reactiv e in atmospheric oxygen and requires special storage conditions so that spontaneous combustion is prevented. The complete deprivation of oxygen is required if the elemen tal phosphorus is to be stored safely. In order to reduce the potential combustion risk during storag e elemental phosphorous is
140 Appendix B: (Continued) usually retained under a deep pool or column of water so that it is shielded from all potential free oxygen. The accepte d industrial standard is to store elemental phosphorus under a minimum of six foot depths of water. The six-foot pools of water are commonly constrained by either an earthen berm or dike system. The Victor/Stauffer used a lagoon system in order accommodate water depths of 72Â”. Another means to reduce reactivity can be accomplished by converting elemental p hosphorus into a less reactive form called red phosphorus. Red phosphorus is a much more stable compound for shipping and storage purposes and it greatly reduces th e risk of spontaneous combustion. The less reactive red phosphorus is creat ed by heating elemental phos phorus to approximately 400 degrees Celsius or 777.6 degrees F under an a tmosphere that is free of oxygen. Usually, an inert gas such as such as nitrogen or ar gon can be used as an inert medium in the process of converting elemental phosphorus into red phosphorus (ADF, Walsh EN, 1987). Elemental Phosphorus Toxic Symptomatology The earliest documented poisoning caused by elemental phosphorus in humans was associated with the use of matches, rodent poisons and fireworks. Elemental phosphorus was frequently ingested by accident when matc hsticks were often sucked on or used as tooth picks. Chewing or sucking on thes e matches provided the opportunity for small amounts of elemental phosphorus to be inge sted on a frequent basis. Elemental phosphorus intoxication from sucking on matche s had become well documented as early as the 1830's. Other documented poisonings occurred in the American firecracker
141 Appendix B: (Continued) manufacturing industry where dus ty work areas allowed workers to become contaminated with the inhalation or ingestion of elemental phosphorus. Elemental phosphorus is able to displacing calcium in the blood stream with phosphorus. The loss of calcium can destabilize the heart rhythm and create weak pu lmonary contractions. In clinical trials elemental phosphorus and peanut oil was feed to domestic female rats. The test resulted in a loss of appetite and retardation of we ight gain in the ra t subjects (EPA, 1993). Elemental phosphorus is extremely pois onous in humans. Elemental phosphorus has been directly linked as a causal agent of the bone disease Osteomyelitis commonly referred to as phossy jaw. Phossy jaw is the chronic dental disease symptom that develops after absorbed phosphorus has displ aced structural calcium jaw bone structure with abnormal phosphoric bone structure. Osteomyelitis is a systemic degenerative bone disease that can develop when frequent exposure levels of phosphorus gas en ter the body through existing tooth cavities or structura lly compromised fillings resulting in the necrosis of the lower mouth bone structure. The onset of phossy jaw commonly begins as a mild dental disturbance that evolves in to a major dental infection eruption. If a suspect tooth is extracted the victim of w ho is suffering from phossy jaw will also be effected by the pressure of an infectious discharge. Following the extraction of the suspect tooth the patient will experience a fa ilure of the empty tooth socket to heal properly. If there is a failure of the tooth socket to heal the attending dentist may choose to allow the infected bone material to separa te and then remove it surgically. A dentist might choose to use this strategy in an attempt to conserve as much viable bone structure
142 Appendix B: (Continued) as possible. The conservation of natural bone structure will help to avoid possible permanent facial disfigurement of the victim (International Labour Office, 1983). The cause of Phossy-jaw disease initiati on is not well understood. However, it is believed that small quantities of elemental phosphorus enter into the jawbone via dental cavities or leaking fillings. The elementa l phosphorus reacts with the ambient mouth flora community and the oral flora reacti on precipitates a genera l infection and the Phossy jaw disease commences as a pe rvasive bone necrosis (EPA, 2003). Lethal Dose: Oral/Dermal The lethal dose of test animals is typically determined by exposing a certain controlled population to a toxic dose that kills approxima tely 50% of the sample population. This particular method of determining toxicity to a given population is a c linically determined lethal dose to 50% of a populati on or what is known as an L.D.-50 dose. As a general rule female rats are used as the sample popul ation and all results ar e extrapolated to the larger mass of humans. The human oral le thal dose/L.D.-50 of elemental phosphorus has been determined to be approximately 1mg/Kg of body weight. It has been determined that doses as small as 0.2mg/Kg of body wei ght may produce adverse effects in humans. The acute ingestion of elemental phosphorus poisoning of humans appears to have two distinct phases of pr ogression. The initial phase of or al elemental phosphorus poisoning creates a quickly developing cond ition of severe gast rointestinal effects and pain to the victim. The initial symptoms of elemen tal phosphorus poisoning may include: nausea, belching with a strong odor of garlic and vomiti ng with a strong garlic smell. The initial
143 Appendix B: (Continued) stage of elemental phosphorus poisoning may o ccur within 30 minutes after the ingestion event has occurred. Death from cardiovascul ar collapse is possi ble within a 12-hour period. A period of symptom subsidence and apparent recovery lasting about 48 hours frequently occurs. The sec ondary phase of elemental ph osphorus oral poisoning is characterized by the return of the gastroin testinal pain. Elemental phosphorus poisoning symptoms can also include cardiovascular f unction interference and kidney disorders. A high cardiac pulse rate and low blood pressure along with jaundice are also a strong collection of diagnostic symptoms. In bot h phases of elemental phosphorus poisoning smoking, luminescence, and garlic odor feces and vomit are characteristic. The fatty tissues of the body appear to preferentially accumulate elemental phosphorus prior to other tissues. It appears that the catastrophic degradation of the fatty tissues comprising the liver and kidneys is the most common cau sal reason for death following the ingestion of a lethal dose of elemental phosphorus (Clayton and Clayton, 1993-1994). The combustion of elemental phosphorus cause s second and third de gree burns on skin contact and may also cause systemic symptoms similar to those listed in the previous paragraph from dermal absorption at the bur n site. The elemental phosphorus compound is highly toxic to humans as it is readily ab sorbed by the fatty tissues. The acute fatal oral dose of elemental phosphorus in an adul t human ranges: from (15 to 100mg) or an LD50 rate of (1mg/Kg of body weight). Records indicate that humans have survived ingestions of elemental phosphorus exceeding 1 gram. Based on the oral dosage rate of (15 to 100mg) the fatality rate for humans varies between (20% and 50%). The prognosis
144 Appendix B: (Continued) for survival is good if an affected patient su rvives 6 days after the ingestion event has occurred (Ellenhorn, M.J. and D.G. Barceloux, 1988). Elemental phosphorus can be summarized as an anthropogenic chemical that has been exploited for numerous industrial appli cations. Elemental phosphorus is a chemical that requires large-scale chemical production in order to create scale of economy returns on the initial production investment. The final product of elemental phosphorus production is the building block for numer ous agricultural, industrial and military applications under the current economic para digm. Until the late 1970s when energy costs escalated the production of elementa l phosphorus was most often carried out in large manufacturing facilities that are domin ated by very high temperature electric-arc furnace facilities that liberated large quantities of synthetic pollutants. However, there are many other potential issues that may adversely affect the human and biologic community that is located in the vicin ity of an elemental phosphorus manufacturing facility. The complete chemical inventory of all the synergistic by-products of elemental phosphorus production is still not fully unders tood. The incomplete understanding of chemical synergy has left the public a nd the biologic community at risk.
