Description In this research work, four Vertical Electrical Soundings (VES) were carried out in Ewu Town at various locations: Eguare-Ewu, Idunwele-Ewu, Flour Mill Road-Ewu and Eko-Ewu using the ABEM terrameter, by employing the Schlumberger electrode configuration system to determine the level of groundwater.  From the analysis of field data and results of computer iteration, a maximum of four geoelectric layers were obtained. The first layer of geoelectric section was the lateritic top soil with thickness of 1.21m and 11.1m, for VES 1 and VES 2, with apparent resistivity of 438 ohm m and 183 ohm m.  The possible aquiferous zone for sustaining groundwater are within the second and third layers for VES 1 and the fourth layer for VES 2, at a depth of 2.67m to 47m and infinity respectively. The apparent resistivity of the aquiferous layers of VES 1 and VES 2 are 797 ohm m and 362 ohm m respectively, which is fine sand layer.  The apparent resistivity of the aquiferous layers of VES 3 and VES 4 are 5511 ohm m and 129 ohm m respectively with infinity thickness.
