Groundwater Exploration in Parts of Enugu East Local Government Area, Enugu state, Nigeria.

Abstract

Groundwater exploration has been carried in some part of Enugu East LGA, Enugu State, Southeastern Nigeria. The electrical resistivity method was utilized, employing the Schlumberger configuration technique. The area is underlain by Enugu Shale. A total of twelve (12) Vertical Electrical Sounding (VES) was acquired within the study area, employing the Schlumberger configuration. Interpreted VES data show clay/shale lithologies, with thin sandy laminar up to depth of 120meters. Predominance of KQH curve type indicates possible fracture – shale subsurface. Contour maps of layer aquifer resistivity, depth and thickness show variations of the interpreted model parameters. The various contour maps will serve as a useful guide for groundwater exploration in the study area.
