Abstract

The primary objective of this research work, is to reduce youth restiveness in the area to its lowest ebb by setting up additional pure water industry or factory where these youths will be gainfully employed and hence the need to prospect or search for additional aquifer or water bearing formations became inevitable. Ten (10) vertical electrical sounding (VES) (uniformly distributed) based on electrical resistivity method was carried out in a geophysical survey in order to study aquifer properties. These properties include depth, thickness and nature of soil above the aquifer. Schlumberger array of VES was conducted in Isihor Village and its environs area of Edo state, Nigeria. The resistivity soundings were carried out with semi current electrode spacing in the range 1-632m using six (06) points per decade to determine the depth, thickness of the recommended  aquifer. The geophysical results were used to determine the depth,  thickness of the recommended aquifer or water bearing formation and the thickness of the sandy soil above it. The resistivities of the detected aquifer varied from 800 ohm-m to 9000 ohm-m while its depths varied from 15m to 120.0m. The thickness of the detected aquifer which varied from 10m to 60m enable us to known the probable area for future drilling operation.
