Groundwater Potential Investigation Using Electrical Resistivity Method in BASUG New Site Main Campus Gadau, Bauchi State, Nigeria

Abstract

The study examined the use of vertical electrical sounding (VES) method for groundwater potential investigation in BASUG New Site Faculty of Science Main Campus Gadau, Itas/Gadau L.G.A, Bauchi State. The 12 VES points were carried out across the study area using the Schlumberger electrodes arrays with current electrodes separation from 0 to 200 m to each profile of VES points to identify the depths and resistivity value of the identified geo-electric layers. Through analysis using interpex software, the apparent resistivity; depth and thicknesses of the aquifer were generated. The Interpreted geo-electric layers show a sequence of lateritic topsoil, coarse sand, silty sand, clay sand and clayey. Result of the VES curve analysis reveals that the sub-surface is underlained by three to four lithological layers namely; topsoil, coarse sand, silty sand, and clay sand 0-50m, each VES point is 50m that is one profile is 200m.
