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.
