Status of Arsenic Contamination in India Praveen, Rai Ballamoole, Krishna Kumar Vijaya, Kumar Deekshit Anirban, Chakraborty Indrani, Karunasagar Arsenic, Arsenicosis, lndia, Groundwater, Treatment Arsenic （As） contamination of drinking water has been reported from several parts of the world and exposure to high concentrations of arsenic through food and water became a serious public health crisis with a wide range of deleterious health impacts. In lndia, more than 10 million people inhabited in the regions of Brahmaputra and Gangetic plains have chronically been exposed to high levels of arsenic above WHO guideline value for safe levels of arsenic in drinking water. The maximum permissible limit of arsenic in drinking water recommended by the World Health Organization （WHO） is 10μg/L, but in Tndia, due to lack of alternative drinking water source, the accepted level is 50 μg/L set by the Bureau of Indian Standard （BIS）. The actual source of groundwater arsenic contamination, in the Ganga-Brahmaputra basin, is yet to be established, though it is detected in very high concentrations. Considering the chronic toxicity of arsenic, treatment of arsenic contaminated water has become a high priority and treated water must meet drinking water standards. This review presents recent status of arsenic contamination in groundwater, and various methods suitable to be adopted in mitigating its adverse effects on public health in India.
