This study was carried out with the aim of demonstrating the application of vertical electrical sounding (VES) method of investigation in the exploration for groundwater in University of Abuja, Permanent Site and Environs. A total of 12 VES points were probed in the area with AB/2 of 1 – 250m and covering a total area of 6.75km2. ABEM SAS 300c tarrameter was used to generate the data using schlumberger array method. The data was interpreted using computer iteration methods (IPI2Win). Isoresistivity of topsoil, isoresistivity of weathered layer, isoresistivity of basement, weathered layer thickness and a 3-D of weathered layer thickness were also generated using surfer software. The result reveals five curve types (A, H, HA, HK and QH) and it shows variation in the layers available in the study area, some with four geo – electric layers: top soil, lateritic clay, weathered basement and fractured/fresh basement while some with three geo-electric layer: topsoil, weathered and fractured/fresh basements. It also shows variation in the groundwater potentiality of the study area i.e. good (VES 1, 5, 7, 9), moderate (VES 2, 4, 6, 8, 11, 12) and low (VES 3, 10). The good potential area is suggested for drilling of boreholes.

Abstract
This study was carried out with the aim of demonstrating the application of vertical electrical sounding (VES) method of investigation in the exploration for groundwater in University of Abuja, Permanent Site and Environs. A total of 12 VES points were probed in the area with AB/2 of 1 – 250m and covering a total area of 6.75km2. ABEM SAS 300c tarrameter was used to generate the data using schlumberger array method. The data was interpreted using computer iteration methods (IPI2Win). Isoresistivity of topsoil, isoresistivity of weathered layer, isoresistivity of basement, weathered layer thickness and a 3-D of weathered layer thickness were also generated using surfer software. The result reveals five curve types (A, H, HA, HK and QH) and it shows variation in the layers available in the study area, some with four geo – electric layers: top soil, lateritic clay, weathered basement and fractured/fresh basement while some with three geo-electric layer: topsoil, weathered and fractured/fresh basements. It also shows variation in the groundwater potentiality of the study area i.e. good (VES 1, 5, 7, 9), moderate (VES 2, 4, 6, 8, 11, 12) and low (VES 3, 10). The good potential area is suggested for drilling of boreholes.
