Download or read book Best Practice Guide on the Control of Arsenic in Drinking Water written by Prosun Bhattacharya and published by IWA Publishing. This book was released on 2017-07-15 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic in drinking water derived from groundwater is arguably the biggest environmental chemical human health risk known at the present time, with well over 100,000,000 people around the world being exposed. Monitoring the hazard, assessing exposure and health risks and implementing effective remediation are therefore key tasks for organisations and individuals with responsibilities related to the supply of safe, clean drinking water. Best Practice Guide on the Control of Arsenic in Drinking Water, covering aspects of hazard distribution, exposure, health impacts, biomonitoring and remediation, including social and economic issues, is therefore a very timely contribution to disseminating useful knowledge in this area. The volume contains 10 short reviews of key aspects of this issue, supplemented by a further 14 case studies, each of which focusses on a particular area or technological or other practice, and written by leading experts in the field. Detailed selective reference lists provide pointers to more detailed guidance on relevant practice. The volume includes coverage of (i) arsenic hazard in groundwater and exposure routes to humans, including case studies in USA, SE Asia and UK; (ii) health impacts arising from exposure to arsenic in drinking water and biomonitoring approaches; (iii) developments in the nature of regulation of arsenic in drinking water; (iv) sampling and monitoring of arsenic, including novel methodologies; (v) approaches to remediation, particularly in the context of water safety planning, and including case studies from the USA, Italy, Poland and Bangladesh; and (vi) socio-economic aspects of remediation, including non-market valuation methods and local community engagement.
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-12-26 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Download or read book Arsenic Removal from Drinking Water written by Tatiana Bianchelli and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic is a widely distributed, naturally occurring element in the Earth's crust and is present in trace amounts in all living organisms. Higher levels of arsenic tend to be found more frequently in ground water than in surface water. Because small water systems typically rely on wells for drinking water, while the largest systems typically rely on surface-water sources, arsenic tends to occur in higher levels more often in water used by small communities. In the United States, the average level measured in ground-water samples is less than or equal to 1 part per billion; however, higher levels are not uncommon. Compared to the rest of the United States, Western states have more water systems with levels exceeding 10 ppb, and levels exceed 50 ppb in some locations. Parts of the Midwest and New England also have some water systems with arsenic levels exceeding 10 ppb, but most systems have lower levels. EPA projects that 5.5% of water systems, serving 11 million people, are likely to exceed the 10 ppb level. Sources of arsenic in water include natural sources, and releases from its use as a wood preservative, in semi-conductors and paints, and from agriculture and mining. A question of ongoing scientific debate concerned whether significant adverse health effects occur from ingesting arsenic at very low levels. This book reviews EPA efforts to develop a new arsenic rule and summarises key provisions and subsequent events. Included are different ways of actually removing the arsenic and maintaining the healthy level that is required by the EPA.
Download or read book Arsenic Contamination in Asia written by Hiroshi Yamauchi and published by Springer. This book was released on 2018-11-11 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides valuable new insights into preventive measures for chronic arsenic poisoning, exploring the various causes, metabolism and toxicity, preventive drugs, functional foods and various methods for removing arsenic from contaminated water. The mechanisms of chronic arsenic poisoning vary between countries and regions, and the pathological difference, though reported on, is still only poorly understood. As large-scale chronic arsenic poisoning is concentrated in Asia, the contributions in this book were written by pioneers from Asia. Further, the management of removed arsenic has not yet become standardized, and this volume will serve as a vital source of new ideas by highlighting significant detoxification methods aimed at the disposal of arsenic. Arsenic Contamination in Asia represents a valuable sourcebook for scientists working in the fields of environmental health, occupational health, environmental science, fisheries science, agriculture, pharmacy, analytical chemistry, and clinical medicine. Also, beginning researchers, seasoned experts, and students who are seeking comprehensive information on the natural sciences including medicine will find this work thought-provoking, instructive and informative.

Download or read book Arsenic Removal from Contaminated Groundwater written by Sirshendu De and published by The Energy and Resources Institute (TERI). This book was released on 2012-01-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of groundwater with arsenic is being considered a pervasive and critical issue in recent years. Large areas in India, Bangladesh, South East Asia, and other parts of the world are suffering from this problem. Arsenic Removal from Contaminated Groundwater presents a comprehensive discussion on various important issues, including state-of-the-art arsenic removal technologies, preparation and performance analysis of laterite, and scale-up issues and design of a household filter. It also expounds the potentiality of raw laterite and treated laterite as low-cost arsenic adsorbents. The efficiency of adsorbent capacity is evaluated using real arsenic contaminated groundwater collected from an affected area in West Bengal, India. The topic is an emerging area and most of the work presented has the potential of field application.

This book was released on 2004-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are a number of treatment techniques that can effectively remove arsenic from drinking water. It is essential for utilities that are in the process of selecting an arsenic removal treatment technology to also identify the types of residuals that would be generated, their expected arsenic concentrations, and pre-treatment strategies that would be required prior to final disposal. This document provides utility guidelines for disposal of residuals containing elevated concentrations of arsenic.Originally published by AwwaRF for its subscribers in 2003 This publication can be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below
