Abstract

Electrical resistivity survey involving six vertical electrical soundings was conducted in Ozoro to assess the groundwater potential of the area. Record of apparent resistivity and electrode spread were analysed using curve matching and computer iteration technique and the outcome compared with record of existing borehole. Result revealed the presence of four geoelectric strata which are topsoil, fine-medium grain sand, clay-clayey sand and coarse-medium coarse sand. The fourth layer with a resistivity range of 648-917 Wm and depth range of 10.7-18.0 m is identified as the aquifer layer. Result also revealed that the aquifer layer is overlaid by a clayey aquitard of 4.2 m thick. It is recommended that the sourcing of water for domestic purpose by the people should be done in excess of 18.0 m.
