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.

Key Features: Detailed description of hydrogeochemistry of arsenic-contaminated groundwater. Coverage of technologies of arsenic removal from contaminated groundwater using laterite-based adsorption technique. Significant insight on scale-up and design aspects of household and community filtration systems. Unique focus on the preparation and performance of raw laterite and treated laterite for arsenic removal.
