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 Nitrates in Groundwater written by Larry W. Canter and published by CRC Press. This book was released on 1996-09-18 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This time-saving book provides extensive coverage of all important aspects of nitrates in groundwater, ranging from prevention to problem assessment to remediation. It begins by highlighting the nitrogen cycle and related health concerns, providing both background information and a unique perspective on health issues. It then analyzes subsurface processes and the factors and practices that affect them. It thoroughly reviews aquifer vulnerability mapping, an emerging new management tool, and contains a nitrate pollution index that can be used in evaluating actual or potential nitrate pollution from agricultural areas. Best Management Practices are described and evaluated, and possible treatment measures are also explored. Thoroughly researched and well-organized, Nitrates in Groundwater provides a vivid snapshot of the status of nitrates in groundwater today.

Download or read book Sprinkle and Trickle Irrigation written by Jack Keller and published by Springer. This book was released on 2012-11-05 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design text, Sprinkle and Trickle Irrigation, opens up a new and clear window through which to view the physics, economics, design, and manage ment of pressurized irrigation systems. A broad array of system types and ap plications have been covered in detail to provide for complete understanding of systems design. Topics include soil-water-plant relations, general planning con cepts, hydraulics, economics, sizing, operation, maintenance, and special uses. Pressurized irrigation system types covered include hand-line, wheel-line, solid set, traveler, center-pivot, linear-moving and big-gun-sprinkler systems, pump ing systems, and a broad array of trickle system components. The work in this text culminates earlier major works by Jack Keller on the W. R. Ames Company Irrigation Handbook (1967), Rain Bird Sprinkler Man ufacturing Corp. 's Trickle Irrigation Design (1975), and the USDA-Soil Con servation Service's National Engineering Handbook, Section 15: Irrigation Chapter 11: Sprinkle Irrigation (1983) and Chapter 15: Trickle Irrigation (1984). These earlier works form the foundation upon which the majority of currently used design texts are based. The years of design and troubleshooting experiences of the authors and wide ranges of environments and design appli cations in which they have worked have resulted in the substance and robustness of this text in stated relationships and procedures.

Download or read book Ground Water Vulnerability Assessment written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the need to protect ground water from pollution was recognized, researchers have made progress in understanding the vulnerability of ground water to contamination. Yet, there are substantial uncertainties in the vulnerability assessment methods now available. With a wealth of detailed information and practical advice, this volume will help decision-makers derive the most benefit from available assessment techniques. It offers: Three laws of ground water vulnerability. Six case studies of vulnerability assessment. Guidance for selecting vulnerability assessments and using the results. Reviews of the strengths and limitations of assessment methods. Information on available data bases, primarily at the federal level. This book will be indispensable to policymakers and resource managers, environmental professionals, researchers, faculty, and students involved in ground water issues, as well as investigators developing new assessment methods.

Download or read book Nitrates in Groundwater written by Lidia Razowska-Jaworek and published by CRC Press. This book was released on 2004-08-15 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book devoted entirely to the problem of nitrate risk and behaviour in groundwater, this volume includes twenty-seven papers selected from those presented during the Euromeeting of the International Association of Hydrogeologists "Nitrate in Groundwater in Europe" held in Wisla, Poland in 2002. The problems presented and discussed in Wisla covered all aspects of nitrate pollution of groundwaters globally, while the articles describing the case studies focus on groundwater in Europe. The remaining chapters examine the main chemical and physical processes which affect nitrate in groundwater, as well as describing nitrate distribution in various aquifers, seen as an essential problem areas of groundwater protection.
