Book Description
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.

Book Description
The concern over groundwater contamination has focused attention on the processes that influence the fate of chemicals in soil water systems. A major concern of groundwater contamination is the passage of these chemcials through the unsaturated zone and the relatively thin cover layers overlying the aquifers. Pollution due to diffuse sources is probably the most difficult to model. This is because the loads are usually non-homogeneous and they are also governed by spatially and temporally non-homogeneous, but dynamic, processes of chemical and biochemical phenomena.In this book, the estimation techniques and transfer functions of required input data from existing databases in geographic information systems are provided. Spatially variable input data, such as the type of soil, hydrological conditions, intensity of land use and atmospheric deposit of pollutants, are derived from basic land and climate characteristics. A model for the evaluation of land use and water management is also described. In addition, examples of field and regional studies on water management and policy analysis are provided.

Book Description
This collection of 11 papers introduces broad topics covering various professional disciplines related to the research arena of land use and water quality. The papers exemplify the important links between agriculture and water quality in surface and ground waters as well as the pollution problems around urban areas. Advancement of new technologies for analyzing links between land use and water quality problems as well as insights into new tools for analyzing large monitoring datasets are highlighted in this collection of papers.

Book Description
This book combines multidisciplinary studies on the environmental consequences of intensified use of land and water, and the fusion of land to provide food for a growing population. Studies on water, vegetation, and soil are addressed from an environmental management perspective with a special focus on the relation between natural elements and humans. This book considers the essential dynamics of humans and the natural environment, which is especially important in areas with shallow water-table that influence directly on agricultural activities (crops, livestock, and forests), land management, flooding, droughts, waterlogging, salt-affected soils (saline and sodic) and variation in obtained water quality in wells where these processes as related to the local and regional geomorphology control. The studies present hydrological processes towards the definition of an adequate use of soil and water with consequences of its management on the environment. Also, water study procedures are presented as well as their relation to other elements of the landscape. Methodologies such as the Tóthian flow system concept are recognized by different authors to provide the reader with solid interdisciplinary analyses of related environmental components such as soils, vegetation, surface water, geomorphology, geological framework and groundwater physical-chemical composition.
