INTRODUCTIONWhat is Ground Water?Groundwater (or ground water) is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations.

Efforts made by State Govt. Efforts made by State Govt.The Govt. of West Bengal constituted a SteeringCommittee (First Committee) in May 1988 to examineand investigate the Arsenic contamination of groundwater in the districts having reports of suchcontamination. The Committee submitted its finalreport in 1991 with the following majorrecommendations; Only the deep 3rd aquifer should be tapped fordrinking water supply. The water in new tube wells should be testedfor Arsenic prior to commissioning. The yield from the 3rd aquifer should be soregulated as to avoid large-scale vertical leakageof Arsenic-rich water from the Upper Zone
