Arsenic in Ground Water by Alan H. Welch,Kenneth G. Stollenwerk Pdf

Interest in arsenic in ground water has greatly increased in the past decade because of the increased awareness of human health effects and the costs of avoidance or treatment of ground water supplies used for consumption. The goal of this book is to provide a description of the basic processes that affect arsenic occurrence and transport by providing sufficient background information on arsenic geochemistry and descriptions of hi- arsenic ground water, both affected and unaffected by human activity. An understanding of thermodynamics, adsorption, and the speciation of arsenic in solid phases, which are described in first three chapters, is needed to predict the fate of arsenic in ground water systems. Large-scale and deep movement of ground water can and has redistributed arsenic in the near surface environment, as described in the next two chapters. These large-scale systems can affect large volumes of both ground water and surface water, such as in the Yellowstone system, and can produce mineralised zones that subsequently release arsenic to ground water supplies. Regional identification of high-arsenic ground water and its consumption as described in the next three chapters clearly demonstrates a need for increased wat- quality monitoring, particularly in south and southeast Asia. Chapters 9-11 provide examples of high arsenic ground water associated with sulfide mineral oxidation and alkaline conditions. Finally, smaller scale studies of the effects of human activities that have produced high-arsenic ground water and methods for attenuation of ground water are presented.

Arsenic in Drinking Water by Subcommittee on Arsenic in Drinking Water,Commission on Life Sciences,Division on Earth and Life Studies,National Research Council Pdf

The U.S. Environmental Protection Agency (EPA) has been considering a more stringent regulation of arsenic in water. A significant reduction in the maximum contaminant level (MCL) could increase compliance costs for water utilities. This book discusses the adequacy of the current EPA MCL for protecting human health in the context of stated EPA policy and provides an unbiased scientific basis for deriving the arsenic standard for drinking water and surface water. Arsenic in Drinking Water evaluates epidemiological data on the carcinogenic and noncarcinogenic health effects of arsenic exposure of Taiwanese populations and compares those effects with the effects of arsenic exposure demonstrated in other countries—including the United States. The book also reviews data on toxicokinetics, metabolism, and mechanism and mode of action of arsenic to ascertain how these data could assist in assessing human health risks from arsenic exposures. This volume recommends specific changes to improve the toxicity analyses and risk characterization. The implications of the changes for EPA’s current MCL for arsenic are also described.

Best Practice Guide on the Control of Arsenic in Drinking Water by Prosun Bhattacharya,David Polya,Dragana Jovanovic Pdf

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.

Safe and Sustainable Use of Arsenic-Contaminated Aquifers in the Gangetic Plain by AL Ramanathan,Scott Johnston,Abhijit Mukherjee,Bibhash Nath Pdf

This book offers a meaningful and practicable guide to better management of arsenic problems in the groundwater of the Gangetic Plain. It gathers contributions from distinguished researchers who have been actively working in the area for over a decade. The arsenic contamination of groundwater is a growing concern in the central Gangetic Plain, where the local population’s main sources of fresh water are surface water, groundwater and rain water; of these sources, only the last two generally meet the most important criteria for drinking water in their natural state. Natural geological changes are presumed to be the primary reason for arsenic contamination in this region. Further, most of the people living in this area have developed the habit of drinking water (groundwater) from the arsenic-contaminated tubewells in many parts of the region. As a result, many are suffering from arsenicosis and many more are at risk. Since the cause of arsenic contamination in groundwater still remains unclear, this book seeks to address the arsenic issue in this region by pursuing a holistic and systematic scientific approach. Accordingly, it delineates various sources, processes, hypotheses and remedial approaches that are needed to manage the arsenic contamination in the Central Gangetic Plain.
