Arsenic contamination of groundwater: mechanism, analysis, and remediation

Arsenic contamination has become a global phenomenon and with the developmentof advanced technological detection tools, more affected geographical areas have been identified. This book offers an assessment of environmental health risks and economic impacts, and the technologies available for dealing with the problem. Written in a straightforward style, it is designed to update knowledge on the dynamics of natural arsenic from the aquifers through groundwater to the food chain and outlines efficient techniques for arsenic removal and aims to increase awareness of the problem by administrators, policy makers and company executives.
