Geoelectric Investigation of Groundwater Potential within Mubiand Environs, Adamawa State, Northeastern Nigeria

Abstract

In this paper, ABEM SAS 4000 Terrameter with Schlumberger configuration was used to determine the groundwater potential within Mubi and its environs. The Schlumberger configuration with maximum current electrodes of 100 meters was adopted and a total of twenty-five Vertical Electrical Sounding (VES) was carried out. The results show that the geologic sequence beneath the study area consists of top soil, partly weathered/fractured basement, highly weathered/fractured basement, aquifer with fresh water and presumably fresh basement. The weathered/fractured and aquifer with fresh water horizons constitute the water bearing zones referred to as aquifer with a thickness value of 10.06m to 77.32m and resistivity value of 16.19Ωm to 150.40Ωm. In addition, six distinctive curve types namely H, KH, HK, K, HA and KQ were identified. The results reveal that H curve type dominates the study area with 48%, HK and K curve type have 12% and HA and KQ curve type have 4%. Furthermore, the result shows that out of twenty-five (25) locations considered within Mubi town and Environs, nineteen (19) of them have potentials for ground water.
