INTRODUCTION
Groundwater
is a precious and the most widely distributed resource of the earth and unlike
any other mineral resource, it gets annual replenishment from the meteoric
precipitation. The worlds total water resources are estimated at 1.37 x 108
Million hectares (ha-m). Of these global water resources about 97.2% is
salt water mainly in oceans, and only 2.8% is available as Fresh water. Out of
the 2.8%, 2.2% is available as surface water and 0.6% as groundwater. Even out
of this 2.2% of surface water, 2.15% is fresh water in glaciers and ice caps
and only of the order of 0.01% (1.36x104 M ha-m) is available in
lakes and reservoirs and 0.0001% in streams. Out of 0.6% of stored groundwater,
only about 0.3% (41.1 x 104 M ha-m) can be economically extracted
with the present drilling technology, the remaining is unavailable as it is
below 800 m.
