ABSTRACT Schlumberger Vertical Electrical Soundings for groundwater search within the premises of University ofllorin 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 500m x 650m. 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 Iithologic 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 oflow 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 80-14 7 ohm-m and over 300m wide, while the other lobe oflow 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-man~ oy. t!. r. SSO... m wide. The study concluded· that the area investigated contains two lobes of low resistivity whi~ h could be explored for water supply.
