PROC. NO.19 A DECADE OF PROGRESS IN WATER RESOURCES AMERICAN WATER RESOURCES ASSOCIATION MARCH 1974 RESEARCH AND ADVANCES IN GROUND-WATER RESOURCES STUDIES, 1964-197 4 Garald G. Parker and A. Ivan Johnson 1 One of the gre.at concerns that I have is that we seem to have lost direction as a nation. We seem to have lost that purpose and zeal which has typified this land for the nearly 200 ye.ars of its existence. Ours is a land which has produced a people who conquered technology and developed an abundant society such as the world has never known. We had the commitment to win two world wars and to realize the age old dream of a man walking on the moon. Yet, today, we seem to have lost that purpose and direction. Many severe challenges will go unmet until that vision and purpose has been regained. -Congressman Don Fuqua, D., Fla. Although Congressman Fuqua's concerns for the nation may be well founded, I'm happy to report to this conference of distinguished scientists and engineers that, for the water-resources professionals of this nation, he need have no fears. We continue to press onward at an ever accelerating pace in our research. And, in the development of ground-water science in particular , our progress has been astonishing. During the decade that began with the establishment of the American Water Resources Association in 1964, great changes have occurred in ground-water research and in the nature, quality and quantity of ground-water investigations both at home and abroad. Formerly, by far most such work in the United States was accomplished by ground-water scientists and engineers of the U.S.G.S. (United States Geological Survey), supplemented by a much smaller number of like personnel of a number of State Surveys or State Water Engineers. Largest and most productive of these were in Arizona, California, Illinois, New Mexico and Texas. In these pre 1964 times the colleges and universities of the United States, with a few notable exceptions such as California (Berkeley), Colorado State , Illinois, New Mexico School of Mines and Utah, had no graduate programs leading to the Ph.D. or M.S. degrees in hydrogeology or in hydrology . Most schools taught no courses in ground-water science at all. However , during the 1964-1974 interval this situation changed greatly . There are now more than 60 schools in the United States offering courses or degrees in ground-water science including about two dozen at the Ph.D . and M.S. levels. Abroad, about 40 schools offer similar courses (Todd, D .K.(Ed.) 1970, p. 528-533) . 1 Respectively , Certified Profesmonal Geologist ; Chief Hydrologist and Senior Scientist, Southwest Florida Water Management District, P.O .

RESEARCH AND ADVANCES IN GROUND-WATER RESOURCES STUDIES 43 These changes began chiefly in the l 950's. Most of the earlier courses in ground-water science were taught on the undergraduate levels as a 2 or 3 hour course in the geology department and in some schools the courses were generally taught as an adjunct to the civil engineering course commonly called "'Hydrology , " which ordinarily included chiefly chapters on weather, rainfall, runoff and stream-flow phenomena. Few of the early ground-water courses were more than descriptive and fewer had field or laboratory requirements. Additionally , most of the more successful of these early comses were taught by part-time instructors on temporary leave from local offices oC the U.S. Geological Survey's Ground Water Branch because qualified and competent teachers were practically obtainable nowhere else. It was just such a situation as this that developed at the University of Michigan in the late l 940's. John G. Ferris, one of the world's outstanding ground-water hydrologists, was at that time stationed in Lansing , as District Chief of the U.S. Geological Survey Ground Water Office in Michigan. He was asked by Professors Wisler and Brater of the Engineering Department, to teach a quantitative short course in ground-water hydraulics as an adjunct to their course in hydrology. Ferris accepted and subsequently worked up his lecture notes as a chapter entitled "Ground Water", which was included in Wisler and Brater's very successful college textbook entitled "Hydrology" {1949). Likewise, Ferris' notes formed the basis of his well known contributions to the highly-regarded and subsequently developed U.S. Geological Survey Ground Water Short Courses. In the following year, 1950, C.E. Jacob's chapter on "Flow of Ground Water" was published in Hunter Rouse's ( 1950) great editorial work entitled "Engineering Hydraulics." Of course, a few similar ground-water courses were being taught at other schools at the same time , but it was basically the U.S. Geological Survey Ground Water short courses that sparked the interest in, and enthusiasm for, the teaching of ground-water science in the colleges and universities of the country. These short courses were organized, developed and supervised by the senior author in the period 1951-1956, and were held in a number of different American schools. D1wised chiefly to upgrade the professional capabilities of the employees of the Survey's Ground-Water Branch, they were also attended by many college and university teachers, by employees of State cooperative agencies, of other Federal Agencies and by foreign nationals here in the United States for training with the U.S. Geological Survey. This, then, was the real beginning of ground-water interest by geologic and engineering faculties of the United States on a large scale and led directly to the numerous excellent ground-water courses that are now available in more than 60 American universities and colleges. These schools have, during the past 10 years, established programs leading to the Bachelor's Master's and Doctor's degrees in hydrogeology, ground-water geology, ground-water hydrology and in hydrology. Well over a thousand graduates from these courses are now either teaching or working as professional hydrogeologists or hydrologists in industry, State or Federal Survey's Water Management Districts (my own District currently employs 14 such professionals) consulting firms, and a members of the staffs of several professional societies. In addition to the American scientists and engineers who received either or both their basic and advanced training in hydrogeology at the U.S. Geological Survey Short Courses, several hundred foreign nationals have been enabled to take advantage of these courses. And, in addition to this formal study, most of these foreign student-trainees spent several months to a year or more on a working assignment to one or more of the U.S. Geological Survey field offices where practical experience was gained in "learning by-doing."

44 Parker and Johnson Graduates of this training are now widely scattered all over the world, particularly among the developing countries. Europe has long had excellent hydrogeologic and hydrologic courses available , especially in Belgium, Czechoslovakia, Denmark, England, France, West Germany , Hungary, Ireland, The Netherlands, Scotland, Spain and Switzerland. Others, outside Europe , are in Australia, Ghana, India, Israel, Japan, Peru and South Africa. After the U.S. Geological Survey foreign-hydrogeology trainees returned to their homelands several new ground-water governmental agencies, modelled after the U.S. Geological Survey , were established. Additionally, college and university courses on both graduate and under-graduate levels were begun based largely on the American experience of the trainees. This has been one aspect of our American Foreign Aid programs of which we can be very proud because it has both directly and indirectly helped our less-fortunate foreign neighbors. And this foreign training, too, has had a strong impact on the spread and development of ground-water science. We see more and more published reports of studies, research and general investigations carried on at these recently established foreign ground-water agencies, colleges and universities. Our ground-water literature is the richer for it. With the expansion of college science and engineering curricula to include basic and advanced courses in groundwater came the availability, for the first time in American experience , of graduates with professional groundwater training. Many of these new graduates still find their first employment with the U.S. Geological Survey, but State Surveys, Water Management Districts and consultants are taking a growing share of each new crop of hydrogeology graduates. Many of the new Ph.D's go directly into teaching and this, of itself, tends to raise the standards of ground-water competence in all areas in which they teach and work. Many of these college teachers make themselves available for part-time work in consulting, and a growing number of these, as well as experienced "graduates" of the U.S. Geological Survey and some State Surveys, have established full-time consulting firms of their own. Thus, for the first time on a nation-wide scale. ground-water competence has lately become available for such matters as the expert planning and development of well fields; the assessment of problems relating to underground disposal of both liquid and solid wastes; the storage of liquids and gasses in subterranean reservoirs from which they can be subsequently withdrawn for use; the disposal of municipal and selected industrial liquid wastes by spray irrigation methods; the artificial recharge of aquifers with excess surface-water runoff (flood waters, chiefly) or AWT (advanced waste treatment) effluents from municipal, industrial or agricultural waste liquids, the control of coastal salt-water encroachment; the dewatering of mines; the conjunctive use of ground-and surface-water supplies; and the appraisal of the water crop of given areas plus ways and means of guiding its development, use, conservation and control. The -rapidly growing numbers of scientists and engineers having competence in ground-water science has led to a vast proliferation of water-resources data and of published reports resulting in the almost exponential growth of the body of knowledge and understanding not only of the ground-water resource itself but how to manipulate it to mankind's benefit without doing irreparable damage to the environment. The growing input of this comparatively large number of newly qualified ground-water professionals has given such people as city planners, real-estate developers, mine operators, and municipal, State and Federal officials a whole new look at water resources. Formerly (and, unfortunately , still in some unenlightened quarters) when new water supplies were needed the first, and all too often the only, look was for a surface-water source. Now, for

PAGE 5

RESEARCH AND ADVANCES IN GROUND WATER RESOURCES S T UDIES 45 the most part, ground-water is also considered and often preferred when big, new supplies are needed. There has been, as noted above, a considerable change in attitude toward ground-water in just the past few years. The public, the State legislatures, the Federal Congress and the dvil engineering profession ( which has traditionally been the water-resources planners and developers) , and all generally seeing ground-water in a new light or from a difference perspective. Ground-water research is now specifically provided for (althou~ not yet adequately) by the water resources act that established the Office of Water Resources Research plus establishing the Water Resources Research Centers (Institutes) in every State. Our water resources problems are complex and demanding, and they grow geomet rically as the population grows arithmetically . The exploding population growth, with its vast thirst for pure, clean water and its all-too-of ten violent impacts on the environment, has caused a shift in ground-water research emphasis. The shift is from where is the water to how much is where and then to how much can be developed without either depleting the supply or harming the environment irreparably . Such complex and difficult problems often assume portents of using water supplies as a means of population controls ; that is, develop no more water for a giveri place and no more people can be supported there! However , much as many people would like to see water supply utilized as a means of putting a cap on population growth. we have never seen it work anywhere. Ways and means are always found to obtain the needed water. New York City, Boston, Denver , Phoenix, Los Angeles and San Francisco are but a few of many excellent examples. The nature of ground-water research has moved from descriptive analysis to quantitative analysis, and from the era of the slide rule through that of the desk calculator to highly complex computers, which not only can solve problems practically impossible to handle manually a few years ago but can do it in a matter of seconds or minutes! New machinery, new methodology and new techniques have become available for ground-water research , much of it , especially the highly sophisiticated , only during the past 10 years. These advances are as far removed from World-War II capabilities as modern rocketry is advanced over the medieval catapults in the waging of warfare . Data gathering, storage, retrieval, sorting and analyzing have become so technically advanced that it is becoming difficult to keep up with newly developed techniques and equipment. A whole host of new sounding research-paper titles bring this trend into focus, such as: 'Quasilinearization and the identification of aquifer parameters" (Yeh , W . W .-G. and Tauxe , G.W. , 1971) ; or "Digital computer simulation for solving groundwater and surface water systems" (Young, R.A. and Bredehoeft , J .D ., 1972) ) ; or •chance-co n strained approach to the conjunctive use of surface water and ground waters. " (Nieswand , G.H. and Granstrom, M.L., 1971). Solving problems such as these are comparatively easy now but could only have been dreamed of in "the good, old days." Clearly , great strides have been accomplished in ground-water research and investiga tions of ground-water resources in the period 1964-1974 . None-the-less, there is room for more improvements and greater advances, particularly in furthering our ability to handle analyses of ground-water systems and their conjunctive uses with surface-water systems . Advances must be made both in geophysics and geochemistry of aquifer systems and their physical and chemical behavior when wholly new stresses or greatly increased stresses are placed upon the systems by such forces as artificial recharge pressures or the storage o f foreign fluids and gases in the aquifers. We need to develop keener understandings of the

PAGE 6

46 Parker and Johnson effects of ground-water development on the environment and how to achieve maximum development of the gound-water resource with minumum (and acceptable) harm to the environment. Finally, we need to tailor our research more and more to the need; of the real world of the city planner, the well driller, the consulting engineer, the legislator, and others who use our data and our findings as essential input elements in their own activities. Our scientific data and our research findings must be so organized and explained that any ordinarily intelligent person can grasp their meanings and utilize our reports as guides in the decision-making processes. In other words, our results must be not only understandable, they must also be useful. And, to further their usefulness, they must have transfer values. In this past 10 years we have seen a tremendous increase in the development of useful information regarding our ground-water resources, together with a great expansion of methodology and technology to handle the data involved. The complexity and mathematical nature of much of it is astonishing. A glance over the following list of selected titles together with a review of Ivan Johnson's analyses of ground-water developments from 1963 to 1970, (Johnson, A.I., 1967; 1971; 1972) will help put this all in perspective. SELECTED BIBLIOGRAPHY The following entries, together with those included in I van Johnson's summary reports (1967, 1971 and 1972, q.v.) include most of the published works on ground-water research both basic and applied, in the period 1964-1974. listings entered in Johnson's reports are not intended to be included herein, and any exceptions to this are by accidentally overlooking double entries. A notable trend is evident when one compares earlier ground-water reports to those of current times, namely , the earlier reports tended to be concerned only with ground-water, per se, and were chiefly descriptive and qualitative. In the past ten years there has been a predominant shift to the inclusion of ground-water studies with other aspects of water resources including surface water and soil moisture, and the influences of the entire environmental framework in which water occurs. Further, the trend is away from the descriptive and qualitative to the evaluative and quantitative . Most current reports are made in the context of systems analysis and commonly include modelling, either digital or electric analogue models and in a growing number of studies use is made of hybrid models. No attempt was made to cover foreign literature, however, some known studies are included in the following listings. Because water-law is currently undergoing changes both in the State and Federal governments, important water-law entries have been included. This listing includes about 800 bibliographric entries.
