Arsenic contamination of groundwater affects about 100 million people worldwide. Countries with elevated groundwater arsenic concentrations include Argentina, Bangladesh, Chile, China, Cambodia, Canada, Ghana, Hungary, India, Laos, Mexico, Mongolia, Nepal, Pakistan, Poland, Taiwan, Thailand, Vietnam, and the United States. Arsenic Contamination of Groundwater: Mechanism, Analysis, and Remediation includes an assessment of environmental health risks and economic impacts and the technologies available for dealing with the problem. It explores developments in the geochemistry, detection, measurement, removal, and toxicology of arsenic.

To develop technology for remediation, sound knowledge of geochemistry, analytical chemistry, environmental chemistry, and separation chemistry, including chromatography, is necessary. This book brings all these approaches together and:

• Defines the nature and scope of the problem, including ways arsenic gets into the food chain

• Focuses on naturally occurring arsenic and explains the mechanism of groundwater contamination

• Describes low-cost analytical methods and testing kits

• Discusses existing and emerging remediation methods, ranging from coagulation with ferric chloride or alum to award-winning solutions

• Draws on the experience and expertise of world-renowned experts in microbiology, analytical chemistry, hydrology, environmental chemistry, and separation chemistry

This is a core reference for scientists working in the fields of geochemistry, analytical chemistry, environmental chemistry, and separation science and technology. It's also a great resource for academic and regulatory personnel working in these fields, plus aid agencies (such as the World Health Organization, World Bank, and UNICEF) and concerned nongovernmental organizations.
