Underground water exploration using electrical resistivity method in Edo State, Nigeria

Abstract

A Geophysical exploration involving the use of vertical electrical sounding was carried out in a sedimentary environment to determine the suitability of the method for underground water studies. The Vertical Electrical Sounding (VES) was done using the schlurnberger electrode array configuration and the schlumberger automatic analysis method of interpretation was adopted. The VES data were obtained from two sites in Edo state, Nigeria. The interpretation of the data showed that the total depth to the aquifer layer is 241.48 m (796.90 ft) and 229.13 m (756.13 ft), respectively. These values conelated with the value 206.1 m (680.00 ft) obtained from the geologic section of a nearby borehole. The high correlation between the VE S results and the borehole values showed that the method is suitable for underground water exploration. © 2010 Academic Journals Inc.
