Arsenic content in groundwater and soils of Ballia, Uttar Pradesh

摘要：

Arsenic pollution in groundwater now appears to be spreading in several parts of India. Ballia district in Uttar Pradesh has a dubious distinction of being another district with groundwater having 16-470 ppb of arsenic. The source of arsenic is not related to sulphide minerals. Due to the prevailing agricultural practice,soils are accumulating large percent of arsenic. Organic matter in the soils is concentrating 15-22 ％ arsenic.Percolating water with high Fe and Mn may increase the arsenic content in groundwater by several folds than that is observed at present.
