The study area is underlain by sedimentary rocks .The was carried out using the electrical resistivity method with schlumberger configuration as a geophysical tool to gather subsurface information which was to define the groundwater aquifers and their thickness.

Three locations were occupied.The apparent resistivities were calculated and plotted on log-log paper. The data were reduced and interpreted by computer iteration method for quantitative interpretation.

The result indicates seven geoelectric at the occupied positions. The results from these layers show the depth of groundwater to be at range of about 77-137m.Therefore, a borehole drilled at this location to this depth would reach an aquifer.

Result of this investigation has shown that the resistivity methods are successful in outlining the hydrogeological conditions of the subsurface.

I hold a BSc in Geology from the University of Benin,Nigeria.I also hold two Diploma qualifications in Science Laboratory Technology and Computer Studies. I worked with Flowlines Geophysicals as an intern.I have also worked with Leading Edge Geophysical Services, representing in different capacities as an Assistant Field Geologist. I was involved and engaged in acquiring, processing and interpreting the field data for borehole using vertical electrical method. This method was also used in subsurface delineation. I have taught and worked with a British Curriculum School.
