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.

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.
