Introduction to Ground Water provides the reader with the fundamental principles of the hydraulic cycle. Also complete with illustrations and real-life case studies, this text takes a comprehensive and realistic approach to the subject of hydrology. It also contains strong interactive computer-based programs for solving and simulating hydraulics groundwater processes.

Continuing in its forty-year history of providing students and professionals with a thorough grounding in the science and technology of groundwater hydrology, this third edition has been completely updated to reflect the tremendous changes in the field. A true essential reference, this book provides a unified presentation of the subject, treating fundamental principles, methods and problems encountered in the field as a whole.

Up-to-date coverage and a unique, multidisciplinary approach. The ongoing effort to protect our valuable ground-water resources necessarily involves scientists and engineers from many disciplines. Ground-Water Microbiology and Geochemistry, Second Edition is designed 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. Carefully revised to reflect the many recent discoveries that have been made in the field, the Second Edition begins with an overview of microbiology, ideal for hydrologists and others who may lack formal training in the field. These initial chapters systematically cover the kinds of microorganisms found in subsurface environments, focusing on their growth, metabolism, genetics, and ecology. The second part of the book offers a hydrologic perspective on how microbial processes affect ground-water geochemistry in pristine systems. It also introduces the different classes of ground-water systems, and gives an overview of techniques for sampling subsurface environments. Readers gain an understanding of biogeochemical cycling in ground-water systems-in coverage unique to this book-and how ground-water chemistry can be used to study microbial processes in aquifer systems. The final section of the book deals with the biodegradation of human-introduced contaminants in ground-water systems, with an up-to-date review of the physiology, biochemistry, and redox conditions that favor biodegradation processes. Ground-Water Microbiology and Geochemistry, Second Edition is important reading for geoscientists, hydrologists, and environmental engineers, as well as for water planners and lawyers involved in environmental issues. It also serves as a compelling text for upper-level undergraduate and graduate courses in ground-water chemistry.

New exploration tools and techniques for a breakthrough paradigm of regional groundwater occurrence. Fresh water is undoubtedly our most precious resource aside from the air we breathe, and the only commodity whose cost has steadily risen over time. At the same time, our understanding of the origins, pathways, and recharge mechanisms of the earth's most valuable "economic" mineral-groundwater-remains in the nineteenth century. It is ironic that this scientific anachronism is contributing to a global shortage of available fresh water supplies while oil, gas, and mineral discoveries have proliferated, vastly increasing the world's energy, precious metals, and industrial mineral reserves. Modern Groundwater Exploration details applications and results of proven twenty-first- century technologies and geological concepts adapted from the oil, gas, and mineral exploration industries for evaluating, developing, and managing previously undiscovered, massive, sustainable groundwater resources. Unprecedented in both its scope and authority, this timely book presents: -A new groundwater paradigm, coined Megawatershed, which accurately and comprehensively describes the earth's natural complex groundwater systems -Innovative exploration, drilling, and testing technologies that make major new ground-water sources more locatable and cost-effective to produce than ever before -Actual case studies in which megawatershed methods have identified vast quantities of new water and brought new hope to previously arid and desperately water-short locales -Chapters by former OECD DAC chairman Alexander R. Love, geopolitical analyst Dr. Ewan Anderson, and former director of the Trinidad and Tobago Water Resources Agency Dr. Utam Maharaj on the tremendous global implications of the megawater-shed paradigm. These experts explore the many beneficial applications of megawater-shed development, from macroeconomics to development of small island developing state (SIDS), and from critical environmental issues to water conflict resolution and the potential for a second "green revolution" The world's need for clean, dependable water is more urgent-and addressable-than ever before. Let Modern Groundwater Exploration introduce you to the authors' revolutionary megawatershed paradigm, along with the latest concepts and technologies for accessing vast reservoirs of groundwater-still today's safest, cleanest, and most plentiful water resource.

After years of research and development, environmental and agricultural professionals now have an array of methods for characterizing soil processes. Soil-Water-Solute Process Characterization: An Integrated Approach goes beyond simple technical guidance by also addressing each method's limitations and showing readers how to select alternatives. The wealth of methodological tools creates the need for this holistic text, which addresses the complicating factors such as spatial and temporal variability of soil processes, scale issues, soil structure and the trade-offs between methods. The book focuses on advanced methods for the monitoring and modeling of mass transfer processes in soil

Publisher Comments: Over the last century and a half, groundwaters have become contaminated by a growing number of organic and inorganic substances ranging from petroleum-derived hydrocarbons to radioactive compounds, to cancer-causing hexavalent chromium. The importance of uncontaminated groundwater for agriculture, human consumption, and the environmental health of ecosystems is paramount to the health and productivity of industrial society. Water scientists and managers are focused on developing cost-effective methods to reverse this trend.
Several methodologies have been developed, however few are as cost-effective as the use of readily available materials, such as iron and organic compost, for absorbing and isolating contaminants within the matrix of a permeable barrier. The Handbook of Groundwater Remediation using Permeable Reactive Barriers presents readers with this latest technology and developments within four main sections:
1. Innovations in Design, Construction, and Evaluation of PRBs
2. Development of Reactive Materials
3. Evaluations of Chemical and Biological Processes
4. Case Studies of Permeable Reactive Barrier Installations
The Handbook is one of the first references specifically on this topic. It is an excellent fit for graduate students entering this emerging field as well as professionals conducting research or implementing this technology.
