Abstract: Resistivity meter was used to conduct vertical electrical sounding (VES) using the Schlumberger electrical resistivity in the study region for a depth of 150 m. Geophysical study indicates four layers such as top soil, weathered first fractured zone and second fractured zones. 68.52% of study area is dominated by AA, AK and HA type curve-indicating low to moderate groundwater prospective zones. The survey result indicates that Calc-granulite and limestone rock types are better aquifers than the other rock types. GIS overlay indicate that good groundwater potential zone constitutes 93.37 (36.32%), in the study area located in Northeast, East and South edges of the study region. High groundwater potential zones fall in an area of 9.37 (3.65%).
