2. INTRODUCTION
What 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.
What is Ground Water
pollution?
Groundwater pollution (also
called groundwater
contamination) occurs when
pollutants are released to the
ground and make their way
down into groundwater.

6. Efforts made by State Govt.
Efforts made by State Govt.
The Govt. of West Bengal constituted a Steering
Committee (First Committee) in May 1988 to examine
and investigate the Arsenic contamination of ground
water in the districts having reports of such
contamination. The Committee submitted its final
report in 1991 with the following major
recommendations;
 Only the deep 3rd aquifer should be tapped for
drinking water supply.
 The water in new tube wells should be tested
for Arsenic prior to commissioning.
 The yield from the 3rd aquifer should be so
regulated as to avoid large-scale vertical leakage
of Arsenic-rich water from the Upper Zone
