Schlumberger Vertical Electrical Soundings for groundwater search within the premises of University of Ilorin Teaching Hospital (UITH) situated along Ilorin- Jebba road in Kwara State, were carried out with a view to establishing the different subsurface geoelectric layers, the aquifer units and their hydrogeologic properties. Data were collected from 12 VES stations over an area of about 500 m x 650 m. From the quantitative interpretation of the data collected, using the usual method of curve matching with the Orellana-Mooney Master curves and 1-D forward modeling with WinResist 1.0 version software, four Hthologic units were identified. These include: the topsoil, the lateritic layer, the weathered layer/fractured layer and the fresh basement. The weathered and fractured basement constitutes the main aquifer units. The 2-D resistivity structure has elicited 2 lobes of low resistivity which constitutes the prospective zone for water in the area. The first lobe exists below stations 3 and 4 at about 5-15 m depth, with resistivity between 80- 147 ohm-m and over 300m wide, while the other lobe of low resistivity which also signifies a possible borehole location exists below stations 7,8 and 9 at a depth of about 2-14 m, with resistivity between 141-200 ohm-m and over 550 m wide. The study concluded that the area investigated contains two lobes of low resistivity which could be explored for water supply.
