Geoeletrical Investigation for Groundwater Potential In Songhai Integrated Farms, Etigidi, Abi Local Government Area of Cross River State, Southeastern Nigeria

O. A. Oyonga, V.N.Obim, S.I.Ugar

Abstract: There is usually 95 to 100 % uncertainty in drilling successful wildcat water wells, and therefore the need for good geoelectrical investigation for groundwater cannot be overemphasized. Twelve (12) Vertical Electrical Soundings (VES) employing the Schlumberger configuration were carried out to investigate the groundwater potentials of Songhai Integrated farms. The research was necessitated to investigate prolific aquiferous units for the drilling of water wells. The resistivity data from this investigation were plotted and interpreted both manually (using the classical curve matching technique) and with computer modeling (IP2win) resistivity inversion software. Though many points in the area revealed great potentials for groundwater, the aquifers were mostly near surface and maybe prone to contamination if drilled. However, two very prolific aquiferous units at great depths and with good thicknesses were delineated and recommended for the drilling of water wells (boreholes).
