The vertical electrical sounding: A viable tool for the investigation of fresh ground-water in the saline water environment with particular reference to the communities along Warri River.
A resistivity survey was carried out in order to study the fresh ground water conditions (such as the depth to the various aquifers) in the major communities along the Warri River. Vertical electrical soundings by Schlumberger array were carried out at Ogbe-Ijoh, Ode-Itsekiri, Ugbodede, Egbokodo and Omadino. The Schlumberger resistivity soundings were carried out with half- electrode spacing in the range 1-681m and six points per decade. The resistivity data were used to determine the depth and nature of the aquifers, and they showed that there are three aquifer zones (top fresh water, middle brackish/saline water and the bottom fresh water aquifers).
