    Geo-electrical Exploration for Groundwater in Jimba-Oja, Ifelodun Local Government Area of Kwara State, Nigeria
    (Jimma University, Jimma, Ethiopia., 2014) Olawuyi, Kehinde; Oluwole, Victor
    Vertical Electrical Soundings (VES) and Horizontal Profilings (HP) for groundwater exploration in the Agricultural and Rural Management Training Institute (ARMTI) and National Centre for Agricultural Mechanization (NCAM), both located at Jimba-Oja, Ifelodun Local Government Area (LGA) of Kwara state, were carried out with a view to establishing the different subsurface geo-electric layers, the aquifer units and their hydrogeologic parameters. Data were collected from 25 VES stations situated within latitudes 40 39’ and 40 41’ and longitudes 80 22’ and 80 23.5’, three of which have been drilled. 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 lithologic units were identified. These include: the topsoil, the lateritic layer, the weathered/fractured layer and the fresh basement. The weathered/fractured basement constitutes the main acquifer unit. The isopach map of the overburden shows depth to the bedrock varying from 2.8 to 28m. The geoelectrical interpretation of data obtained in this area has permitted the delineation of a lobe of low resistivity which constitutes the prospective zone for water exploration in the area.
