Available in PDF, EPUB and Kindle. Book excerpt: The physical setting in both the Karst and Shallow-Bedrock regions present potential hazards for ground-water contamination. Any management strategies developed for protection of these water resources must consider both of these settings, which in total constitute about 6,800 square miles of land overlying important bedrock aquifers.

Download or read book Regional Ground Water Quality written by William M. Alley and published by John Wiley & Sons. This book was released on 1993-06-15 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Prepared by the Task Committee on Ground Water Protection of the Water Resources Engineering Division of ASCE. This report presents general hydrogeologic information on the occurrence of contamination in groundwater that applies nationwide, as well as specific examples of approaches to groundwater protection used in various regions of the United States. Because management and regulation of resources by regional authorities is one of the most important approaches to groundwater protection, the majority of this report considers the approaches tried by different state and local authorities. The great variety of strategies adopted by these agencies indicates the uniqueness of each aquifer and the need to adjust any strategy to account for site-specific factors.

Download or read book Nitrogen Management and Ground Water Protection written by Ronald F Follett and published by Elsevier. This book was released on 2012-12-02 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplying crops with adequate nitrogen is vital to ensuring food supplies. Once nitrogen is added to the soil, it is subject to chemical transformations of the nitrogen-cycle including transformation to nitrate. Excessive amounts of accumulated nitrate may then leach out of the soil and could potentially enter and contaminate drinking water supplies. The purpose of this book is to examine the subject of nitrogen management and ground water protection. The issue of maintaining ground water quality is addressed primarily from an agronomic point of view. Topics covered include: health and economic aspects of nitrate in drinking water; nitrate sources; ground water nitrate in the USA and other developed countries; transport, leaching and accounting for nitrogen; soil, nitrogen, crop and water management; and nitrate in aquifer systems. The book contains a keyword index and is organized into thirteen chapters, each with appropriate references, tables and figures. Chapter authors are among the leading experts on the subject of nitrate and ground water quality. Readers to whom the book is directed include soil scientists and agronomists, agricultural engineers (irrigation and drainage), environmental scientists, agricultural policy makers, and hydrologists.

Download or read book Nitrate Contamination written by Istvan Bogardi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.
