ABSTRACT:- Sasa community in Ibadan southwestern Nigeria is a fast growing community because of its closeness to several research institutions but there is scarcity of potable water in the community. This research work is therefore aimed at delineating the subsurface geology in the study area using electrical resistivity and to identify aquifer zone that are productive for groundwater exploration. The field survey consists of eight VES using Schlumberger configuration with maximum electrode spacing of 130m. Five lithological layers comprised of top soil, clay/sandy clay, lateritic soil/ laterite, weathered layer and fresh bedrock was delineated from the electrical resistivity survey. Aquiferous zone of sufficient overburden thickness were delineated at an average depth of 11.0m. Most of the hand-dug wells existing prior to this survey were less than the depth obtained in this research which explains why there is abortive borehole and scarcity of groundwater in the study area.

The demand for water has increased over the years due to agricultural and technological advancement, increase in industrialization and population explosion but surface water is grossly inadequate to meet or cope with the ever increasing demands for water, the only sufficient alternative source of perennial water supply is groundwater because it is almost an inexhaustible source of water. Sasa community in Akinyele Local Government Area of Oyo state have suffered enormous challenge of scarcity of potable water and larger percentage of the community relied on hand dug wells while others often travel several kilometers in search of potable water at an exorbitant rate. Several researchers have adopted geophysical methods to identify zones of groundwater
