Hydro geophysical investigation of groundwater was performed using electrical resistivity method. Wenner configuration of electrode arrangement with vertical electrical sounding (VES) was done with IGIS signal stacking resistivity meter model SSR-MP-ATS. Resistivity survey was conducted to obtain the pattern of aquifer distribution in the area and to delineate possible sites for locating aquifers. An estimate of the resistivity and thickness of various subsurface layers at a location could be obtained by successively increasing electrode spacing. The inverse of the resistance measured 1/R was plotted against Wenner electrode separation on a linear graph to detect thin layers at deeper layers in the eight locations under consideration. Analysis of 2 -D cross-section of strip resistivity was done to identify site favourable for recharge structure.
