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.

Accurate risk assessment is critical to pesticide regulation. This authoritative reference provides an exhaustive evaluation of current agrochemical environmental fate studies, a critical review of current EPA pesticide assessment guidelines, and a wide variety of environmental simulation models. Divided into four sections, this well-organized book provides a wealth of data and information vital to anyone involved in environmental exposure assessment, groundwater, surface water, and water contamination, pesticide regulation, and environmental simulation modeling. At your fingertips, you will have the latest information on the development of meaningful environmental fate data and how this information will result in accurate assessment of potential environmental and human hazards. The inadequacy of current regulatory guidelines and the resulting nonscientific assessment of agrochemical environmental fate are discussed in detail. A wide variety of environmental fate studies are included to demonstrate the current use of data to assess environmental fate and potential hazards associated with agrochemical use. Finally, ten chapters discuss the use of computer models that have been developed for analyzing and integrating data from a variety of environmental fate studies on agrochemicals used under various field conditions.

This text illustrates the range of environmental geoscience mapping presently carried out around the world. Specialists in several countries have contributed a number of subdisciplinary and thematic topics including volcanic hazards, landslides, dolines, tsunamis, radon potential, medical geology, rainfall erosion, engineering geology, borehole stratigraphy, lake sediment geochemistry, aggregate resources and remote sensing. The collection, analysis and interpretation of data by geologists, geographers and engineers typically involves the presentation of information in map form, which can range from black/white to colour, 2-D to 3-D and paper copy to digital format illustrations. This volume reaffirms the global need for mapping geoscientific data.

The book contains private views of experts from various countries on the role of geological mapping in sustainable development. New technologies and concepts are presented, which are either awaiting for recognition by Geological Surveys, or are gradually applied in some survey. The target of the book is well worded in the "Summary and recommendations" elaborated by the Ad Hoc Committee at the Advanced Research Workshop on Innovative Geological Cartography, held under NATO sponsorship in Poland in November 2003. After the "Summaries" were issued by the end of 2003, the authors who presented their views at the Workshop, gave a revised version of their papers with more new ideas and material. Generally, the book is addressed to cartographers in Geological Surveys, geologists and geographers co-operating with landuse planners, ecologists and decision makers, who may learn about the state-of-the-art and the enormous information potential of the modern information technologies in Geosciences. The book, however, gives no methodological recipes but, as it was the authors' intention, may and shall be used as a guide-book in modernizing Information Technologies at the local, regional and national levels in Geosciences.
