Application of Surface Geophysical Measurements to Groundwater Investigation

In this research work, the schlumberger array was adopted. The investigation was carried out in two locations; Ambrose Alli University sports ground and Ujemen village area (Ekpoma environs) in the central part of Edo state, Nigeria. The interpretation of the data showed a resolution of six geoelectric layers. Analyzing the curves, the interpretation gave a total depth of 334.90m (1115.22ft) and 362.60m (1207.46ft) from both VES. Since the dropping of the resistivity in the VES curves indicates an aquifer layer, the depth zone corresponds to the existing saturated aquifer in the study area. These values are found to be in close correlation with the hydrogeological profile of the Ishan plateau. A maximum drill depth range of 320m (1065.6ft) to 350m (1165.5ft) in the study area is suggested.
