The difficult struggle to protect our valuable ground-water resources necessarily involves scientists and engineers from many disciplines. To prevail in this effort, these practitioners—including microbiologists, hydrogeologists, geoscientists, and environmental engineers—must have a common understanding of essential ground-water quality issues and problems. That includes a basic grasp of how microorganisms and microbial processes affect the chemistry of ground water in both pristine and chemically stressed aquifer systems. Ground-Water Microbiology and Geochemistry marks the first attempt to bridge the historical lack of communication among these disciplines by detailing—in language that cuts across specialties—the impact of microorganisms and microbial processes on ground-water systems. To bring these diverse practitioners together, the book has been organized in three parts, with each section addressing the information needs of specific disciplines. The first six chapters of Ground-Water Microbiology and Geochemistry provide an overview of microbiology that’s geared to geoscientists who may lack formal training in the field. Here, the book systematically covers the kinds of microorganisms found in subsurface environments, focusing on their growth, metabolism, genetics, and ecology. The second part of the book, which covers four chapters, speaks both to geoscientists and to microbiologists. It offers a hydrologic perspective on how microbial processes affect groundwater geochemistry in pristine systems—an important topic for geochemists since most ground-water reservoirs have not been chemically affected by human activities, and naturally occurring microbial processes have major impacts on water quality. At the same time, Part Two introduces microbiologists to the different classes of ground-water systems, and gives an overview of techniques for sampling subsurface environments. In addition, microbiologists gain an understanding of biogeochemical cycling in ground-water systems—in coverage that’s unique to this book—and of the classic geochemical modeling techniques that are used to study microbial processes. The final three chapters of Ground-Water Microbiology and Geochemistry focus in on microbial processes in contaminated ground-water systems—a topic of central concern to environmental scientists. In this concluding section, microbiologists see how degradation processes depend upon the hydrologic and geochemical environments within which they operate. Having achieved a basic knowledge of microbiological and biochemical concepts from the earlier chapters, geoscientists are fully prepared for this treatment of microbial acclimation and the biodegradation of petroleum hydrocarbons and halogenated compounds. Ground-Water Microbiology and Geochemistry is as graphically impressive as it is far reaching. High-quality, computer-generated illustrations, of particular appeal to visually oriented geoscientists, can be found throughout the book. Equally important is the book’s unusually comprehensive bibliography, which, like the text itself, spans the relevant science and engineering disciplines. The importance of Ground-Water Microbiology and Geochemistry to geoscientists, hydrologists, and environmental scientists has been amply documented. The book should also be required reading for water planners and lawyers involved in environmental issues. It will also serve as a compelling text in upper undergraduate and graduate courses in ground-water chemistry.

Large-scale infilling of the wetlands in the Lake Calumet region of Chicago, Illinois with steel slag has created an aquifer with extremely alkaline ground water, the pH of which can range up to 12.8. To understand the geochemistry of this aquifer, we examined samples of ground water and the associated slag and weathering products from four sites. We also considered several potential remediation schemes to lower the pH and toxicity of the water. The principal cause of the alkaline conditions is the weathering of calcium silicates within the slag. The resulting ground water at most of the sites is dominated by Ca2+ and OH, which form a temperature-sensitive pH buffering system. Where the alkaline ground water discharges in springs, atmospheric CO2 dissolves into the water and thick layers of calcite form. Iron, manganese, and other metals in the metallic portion of the slag have corroded to form more stable low-temperature oxides and sulfides. Fe and Mn in the slag, as well as steel additives such as Ni and Mo, react to form insoluble phases; these metals did not accumulate in large concentrations in the ground water. Calcite precipitated at the springs is rich in a number of heavy metals, suggesting that the metals moved through the system as particulate matter. Air sparging appears to be an effective remediation strategy for reducing the toxicity of discharging alkaline waters. Microbiologists have long believed that highly alkaline conditions are poorly supportive of microbial life, in part because an environment lacking in hydrogen ions (H+) is likely to interfere with the proton motive force needed by most respiring organisms to synthesize ATP, and with the need to maintain a circum-neutral intracellular pH (Horikoshi and Akiba, 1982). Here I describe a diverse microbial community that inhabits extremely alkaline (pH ~ 12-13) ground water from the Lake Calumet region. Using microbial culturing, genetic sequencing, and microcosm experiments, I confiimed the presence and growth of a variety of alkaliphilic ß-Proteobacteria, Bacillus, and Clostridium species at pH up to 13.2. Many of the bacterial sequences most closely matched other alkaliphiles found more moderately alkaline waters around the world. Oxidation of dihydrogen produced by reaction of water with steel slag is likely a primary energy source to the community. These results extend upward the known range of pH tolerance for a microbial community by as much as two pH units. The microbial community may provide a source of novel microbes and enzymes that can be exploited under alkaline conditions.

Earth scientists, who have worked together for 6 years in the priority pro gram "Hydrogeochemical Processes in the Hydrological Cycle Within the Unsaturated and Saturated Zones", have summarized the results of their research in this volume. This is the occasion to take stock and then look ahead. The priority program was set up by the Senate of The Deutsche Forschungsgemeinschaft in October 1981. This was preceded by lengthy and careful preparation by a Program Committee, and was finally recom mended by the Senate Commission for Joint Research in Earth Sciences. The main aim was the interdisciplinary research of geochemical processes in natural systems in the total underground water cycle, whereby water pollution was not to be considered. Officially started on 1 September 1982, the program has received a grant of DM 10. 9 Mio. from the DFG, and this has enabled it to support a total of 50 projects. Although at the beginning, practice-oriented projects, which were funded elsewhere, were not to be included, many of the results are applicable. The four categories presented were investigated with vary ing intensity. An early concentration on certain representative fields of measurement and research areas proved to be the right approach - this avoided a waste of effort in other fields. During the period of the priority program, new and topical questions arose, e. g.

Ground water serves as the main source of drinking water for 50% of the United States as a whole—and for 97% of rural populations, in particular. In addition to public concern with point sources of contamination, such as landfills and hazardous waste disposal sites, current attention has now come to focus on the overall quality of ground-water resources. Regional Ground-Water Quality offers the first detailed guidance for conducting ground-water quality investigations in a regional context. This exceptional volume combines hydrogeologic and geochemical principles, as well as statistical principles, within a unique conceptual framework that helps readers produce efficient, meaningful, and successful ground-water assessments. Regional Ground-Water Quality will be a valuable resource when first approaching a regional-scale study and when designing specific regional-scale studies. Throughout the book, topics emphasize the value of studying regional ground-water quality at multiple spatial and temporal scales. Up-to-date coverage of essential processes and methodologies includes: multi-scale design concepts for regional ground-water quality studies the fate and transport of organic and inorganic materials, including nitrates, pesticides, pathogens, acid precipitation, natural radionuclides, saltwater intrusion, and problems in karst aquifers basic concepts of organic and inorganic chemistry a review of environmental isotopes and geochemical modeling statistical concepts for ground-water quality surveys and geostatistical analysis the effects of surface-water/ground-water interactions on ground-water quality the relationship between ground-water quality and land use regional geochemistry principles Readers will be brought completely up to date with the latest research in ground-water assessments, such as novel methods for dating young ground water, including the use of CFCs, tritium/helium-3, and krypton-85. The book also examines the uses of organic compounds as time and source markers, ground-water vulnerability analyses, applications of subsurface microbiology at the regional scale, and design of well-water surveys. Invaluable case studies drawn from international projects graphically demonstrate concepts discussed in the book. These case studies describe successful regional ground-water assessment efforts conducted in various areas and include a look at the uses and limitations of existing ground-water quality data. A first-of-its-kind resource, Regional Ground-Water Quality will be essential reading for scientists and engineers in hydrology, water resources, agricultural sciences, and environmental sciences. It will also be of interest to engineers and R&D personnel in government, industry, and private consulting, as well as to professionals involved with the design and interpretation of studies.
