Groundwater potential and the strength of the aquifer overburden protective layer to prevent contaminants into groundwater aquifer within the University of Delta Main Campus were assessed with Vertical Electrical Sounding (VES). Ten sounding points were carried out using Petrozenith PZ-02 Terrameter with the Schlumberger array. The VES data were processed with IPI2WIN software and delineated eight to nine geoelectric layers of lateritic topsoil, clayey sand, sandy clay, fine grained sand, fine to medium grained sand, medium grained sand, medium to coarse grained sand, coarse grained sand and sandy clay/clay. The aquiferous layer located between the sixth and eighth layer exhibited varying resistivity (2037Ωm to 300098Ωm), thickness (59.93m to 88.92m) and depth (106.75m to 140.80m). Dar-zarrouk hydraulic parameters were derived from values of aquifer resistivity and thickness. Hydraulic conductivity ranged from 6.90m/day to 9.70m/day, transmissivity from 413.65m2/day to 850.11m2/day, longitudinal conductance from 0.0002892 mho to 0.040411 mho and transverse resistance from 122,118.15Ωm2 to 263, 000588.72Ωm2.The aquifer storativity ranged from 0.0001798m-1 to 0.0002668m-1. Aquifer overburden protective layer was rated poor and highly vulnerable to contaminants. However, aquifer showed high potential of portable water sufficient to meet the needs of the University community. Hydrogeochemical study is recommended to determine the water portability.
