Groundwater Arsenic in India: Source, Distribution, Effects and Alternate Safe Drinking Water Sources
2013 (English)In: Reference Module in Earth Systems and Environmental Sciences, Elsevier, 2013Chapter in book (Other academic)Text
Elevated natural groundwater arsenic, a carcinogen, has created a severe environmental health crisis in several parts of India. Since the discovery of groundwater arsenic and arsenicosis in West Bengal, in 1984, a huge wealth of information has been generated by groundwater arsenic research during the last three decades. The principal mechanism of arsenic mobilization in groundwater is believed to be reductive dissolution of Fe-oxyhydroxides in aquifer sediments. Arsenic enriched groundwater used for irrigation also leads to long-term risks for arsenic enrichment in the soils and bioaccumulation in crops. Various studies are ongoing to develop a holistic approach for arsenic mitigation.
