Delineation of aquifers in basaltic hard rock terrain using vertical electrical soundings data

The region under investigation for groundwater exploration is a part of the eastern fringe of Deccan traps in Kalmeshwar Taluk of Nagpur district. In this region, groundwater is the main source of water supply for drinking and irrigation purposes. Presently, the known source of groundwater is the upper weathered mantle in the depth range of 8–15 m. This source of groundwater has been overexploited because of increasing demand of water supply and is unable to meet the present requirement. The present work deals with the delineation of new sources of groundwater at deeper levels concealed within and below the traps by using vertical electrical sounding surveys in order to meet the increasing demand of water supply.
