AQUIFER DELINEATION AND PROTECTIVE CAPACITY IN THE UNIVERSITY OF PORTHARCOURT USING RESISTIVITY METHOD

Aquifer delineation and the assessment of protective capacity at the University of Port Harcourt were conducted using the electrical resistivity method. Vertical Electrical Sounding (VES), utilizing the Schlumberger electrode configuration, was employed to assess groundwater potential and evaluate the protective capacity of the overburden layers. The study aimed to determine the presence and depth of aquifers, as well as the ability of the overlying layers to protect these aquifers from surface contamination. The geophysical data revealed multiple subsurface layers layers, including sandy and clayey formations, with varying resistivity values. Aquifers were identified based on their resistivity zones, while the overburden protective capacity was evaluated using longitudinal conductance. The results indicated that Abuja campus exhibited weak protective capacity, Delta campus exhibited weak protective capacity, and Choba campus exhibited moderate protective capacity. These findings are essential for groundwater management and sustainable water resource development on the University of Port Harcourt campuses.
