Abstract : The importance of groundwater for domestic, industrial and agricultural uses and its readily and locally available characteristics has lead to indiscriminate extraction of this precious natural resource. Technological development in construction of deep tube wells; water abstraction devices and pumping methods have also contributed to large-scale exploitation of groundwater from depths exceeding 300m below ground level. Drought is a recurrent phenomenon in the Daltonganj and Patan blocks of Jharkhand. It affects the livelihoods of the majority of its people, particularly tribals and dalits living in rural areas.
In the above backdrop the present investigation has been carried out in an area bounded by latitudes 24o5’N-24o15’N to 84o0’S-84o20’S and 23o75’N-24o0’N to 84o0’S-84o10’S situated in Palamau Distt. Of Jharkhand. The area has low groundwater potential due to poor recharge, surface runoff and evapotranspiration. Different low cost techniques were used in the area depending upon the terrain.
