Abstract: Geoelectrical Soundings and exploratory Drill holes have been carried out at Projects Development Institute (PRODA) permanent site Emene, Enugu. Schlumberger electrode configuration was employed in the spacing of the electrodes. The success of geophysical methods depends essentially on the presence of significant contrasts in the earths physical properties. In this study area, good contrasts in electrical conductivity were expected between shale and sandy layers and between dry and water-bearing layers. A reliable interpretation of Vertical Electric Soundings (VES) and Drill Hole data was achieved. Three borehole locations 3, 4 and 5 were recommended which have sand thickness of more than 7meters and water-bearing sand of more than 3meters.
