APPLICATION OF ELECTRICAL RESISTIVITY METHOD IN THE ASSESSMENT OF GROUNDWATER POTENTIALS: A CASE STUDY OF GOMBE STATE POLYTECHNIC, BAJOGA, FUNAKAYE L.G.A, GOMBE STATE NIGERIA

Abstract

Water is a renewable resource which occurs in three forms liquid, solid, vapor (gaseous), all of which extremely useful to man. The water is not only essential for survival of human beings, but also for animals, plants and other living beings. The present study attempted to identify the groundwater potential zones in Gombe State Polytechnic Bajoga, Funakaye Local Government Area of Gombe State, Nigeria using Electrical resistivity method for validation. The study made use of thematic maps like Topographic, and Geology maps. Ten (10) vertical electrical sounding (VES) locations were studied using electrode spreads of AB/2. OHMEGA Terrameter was deployed to acquire the data by employing Schlumberger array method. The analysis (interpretations) of the results were assisted by employing Win-Resist, and Microsoft- Excel. The resistivity data interpretation revealed 4 geo-electric layers and the generated distribution curves.
