Characterization and Delineation of Aquifer in Nigeria Rural Communities

Abstract: Hydrogeological work was carried out to providing an alternative source of portable water supply to Omoku and its environs as their major source of water which is surface water had been contaminated/polluted by oil and gas exploration, exploitation and other anthropogenic activities in the area. To obtaining reliable data and achieving the aim, geoelectric sounding method and Schlumberger array was employed with the use of a digital averaging instrument ABEM terrameter SAS 300 model that displays the resistance measurements directly with a maximum current electrode separation (AB) of 100m. WinResist software computer iterative procedure was used, which aided to obtaining interpreted depths and resistivities from field data. The results of the geoelectric survey were tied to various lithologies by calibrating the geoelectric values with borehole data which enabled us to establish the aquiferous zones. The aquifers were located at depth of about 22m to 30m based soil profile and high resistivity values ranging from 3415Wm to 4555Wm. The information from the findings can be successfully used to harnessing and supply safe, portable and sustainable water to the people of Omoku and its environs in Rivers State, Nigeria.
