Geoelectric evaluation of groundwater potential: a case study at Omuma local government area, Rivers State, Nigeria

Rivers State as the nomenclature depicts is a state richly blessed with both surface and subsurface water. As a result of this, there is less problem of water scarcity, especially in the elite cities of the state, but so many other communities due to one reason or the other still wallow in abject water scarcity. In this survey, a total of seven (7) vertical electric soundings were carried out using Schlumberger configuration at Obibi community in Omuma local government area, Rivers State, to ascertain the location and depths to aquifer. ABEM terrameter SAS 300 was used in the survey with electrode spacing AB/2 of 150 m, thus probing to a depth of about 200 m. Geoelectric software (IPI2WIN) was utilized in the plotting, iteration and interpretation of the resistivity data obtained. From the quantitative interpretation and the lithology of the areas, five different subsurface layers were delineated with their geoelectric curve given as AK, AKQ and AKH. Aquifer in these areas is highly prolific and mostly located at an average depth of 52 m.
