Download or read book Optimal Self Protection from Nitrate Contaminated Groundwater written by Richard Ready and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-protection by well owners from potential nitrate contamination is modeled as an optimal stopping problem, where an owner sequentially tests the well and uses the test results to update his or her subjective probability that the well is contaminated. Because nitrate concentrations in a well vary over time, a single test contains limited information about whether the well is contaminated. The optimal self-protection strategy may therefore involve multiple tests or may not involve any tests at all. For Kentucky wells, optimal self-protection reduces a well owner's expected damage from nitrate contamination by 38%, relative to taking no action.

Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together a number of prominent economic studies all of which deal with key water quality issues. The studies focus on the economic aspects of water quality including identifying the polluters' actions and incentives, designing and comparing control mechanisms, analyzing the costs and benefits of water quality programmes, and finally managing transboundary water quality. They all make recommendations for improving water quality through changing incentives, programmes and/or policies.

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 Environmental Policies for Agricultural Pollution Control written by J. S. Shortle and published by CABI. This book was released on 2001-09-05 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the environmental problems associated with agriculture, particularly the use of pesticides and chemical fertilizers and the disposal of animal waste. These have become major policy issues in many countries, with the main polluting effect being on water quality. As with other types of pollution, significant reductions in agriculture's contribution to water pollution requires the application of either enforceable regulatory approaches or changes in the economic environment, so that farmers adopt environmentally-friendly production practices. Providing a review and guide to the policy options and their economic administrative and political merits, the reader can develop an understanding of these options and their merits in the emerging policy context. The principal focus is on the developed world, particularly North America and Europe. The book is aimed at advanced students, researchers and professionals in agricultural economics and policy, and environmental and pollution sciences.
Download or read book Wastewater use in agriculture Review of impacts and methodological issues in valuing impacts written by Intizar Hussain and published by IWMI. This book was released on 2002 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this paper is to provide a review of the characteristics of wastewater used for irrigation, and the reasoning behind the international guidelines presently used in regulating wastewater reuse for agriculture. This paper presents various systems of wastewater treatment available and discusses their benefits and shortcomings. A selective review of recent empirical studies identifies major impacts both positive and negative impacts of wastewater irrigation. Finally, the paper provides the review of environmental valuation techniques for analyzing impacts of wastewater uses in agriculture, and suggest a framework for application of some of these techniques. This framework will be applied to a developing country case study (Faisalabad area in Pakistan), in the ongoing IWMI research program.
Download or read book Environmental Impact of Genetically Modified Crops written by Natalie Ferry and published by CABI. This book was released on 2009-01-01 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic modification of crops continues to be the subject of intense debate, and opinions are often strongly polarised. Environmental Impact of Genetically Modified Crops addresses the major concerns of scientists, policy makers, environmental lobby groups and the general public regarding this controversial issue, from an editorially neutral standpoint. While the main focus is on environmental impact, food safety issues, for both humans and animals are also considered. The book concludes with a discussion on the future of agricultural biotechnology in the context of sustainability, natural resource management and future global population and food supply.

Download or read book Remediation of Nitrate Contaminated Groundwater Using a Biobarrier written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A biobarrier system has been developed for use in remediating shallow alluvial groundwater. This barrier is made from highly porous materials that are relatively long-lasting, carbon-based (to supply a limiting nutrient in nitrate destruction, in most cases), extremely inexpensive, and easy to replace. In a series of laboratory studies, we have determined the effectiveness of this barrier at destroying nitrate and perchlorate in groundwater from Mortandad Canyon at Los Alamos National Laboratory (LANL). This groundwater was obtained from a monitoring well, MCO-5, which is located in the flowpath of the discharge waters from the LANL Radioactive Liquid Waste Treatment Facility (RLWTF). Water with elevated nitrate levels was discharged from this plant for many years. Recently, the nitrate levels have been brought under the discharge limits. However, the historical discharge has resulted in a nitrate plume in the alluvial groundwater in this canyon. The LANL Multi-Barrier project was initiated in 1999 to develop a system of barriers that would prevent the transport of radionuclides, metals, colloids and other contaminants, including nitrate and perchlorate, further down the canyon in order to protect populations down-gradient. The biobarrier will be part of this Multi-Barrier system. We have demonstrated the destruction of nitrate at levels up to 6.5-9.7 mM nitrate (400-600 mg/L), and that of perchlorate at levels of about 4.3 [mu]M perchlorate (350 ppb). We have quantified the populations of microorganisms present in the biofilm that develops on the biobarrier. The results of this research will be discussed along with other potential applications of this system.
