Electrical resistivity method has been identified to be one of the most suitable geophysical method/technique for groundwater or borehole development. Therefore, this research work was carried out using Vertical Electrical Sounding (VES) to recommend a suitable location for borehole drilling in Unity secondary school compound, Owo LGA, Ondo state with the specific objectives of delineating lithological unit that contributes the overburden using resistivity parameters, to identify the aquifer units and delineate the thickness and lateral existent. The Schlumberger electrode configuration was adopted for the field investigation. Two Vertical Electrical sounding stations were occupied during the survey in the area. A and H curve types were obtained from the field data. Quantitative and qualitative interpretation was carried out that reveals Topsoil, Lateritic hardpan/clay, Fresh basement and fractured basement that underlie the area.
