Aquifer characteristics evaluation enables the determination of aquifer’s ability to recharge as well as discharge. However, knowledge of aquifer characteristics has been scarce at Kingsley Mbadiwe University and Its Environs. Thus, geophysical and hydrogeological investigations involving vertical electrical sounding (VES), pumping test and well logging were conducted in KOMU, Imo State Nigeria, to evaluate the aquifer characteristics as well as the groundwater protective capacity of the area. Twenty-Five (25) VES, using the Schlumberger configuration, were carried out. The vertical electrical sounding data were processed using a combination of curve matching and computer modeling using the IP2WIN software. The aquifer resistivity across the study area varies from 90 Ωm at 5 Star Hotel Obiohia, KOMU (VES 24) to 5872 Ωm beside the Stadium KOMU (VES 9). The depth to the water table across the study area varies from 1.43 m at Medical Centre KOMU (VES 13) to as high as 82.7m at Faculty of Sciences KOMU (VES 2) Southeastern parts of the study area. The aquifer thickness across the study area varies from 2.18m at 5 Star Hotel Obiohia, KOMU Environs (VES 24) to 126m at Benahllis Hotel, KOMU Environs (VES 14). The groundwater potentials of the studied area range from fair to good, with the areas underlain by the Benin Formation having better groundwater potentials, according to the interpretation of a variety of aquifer characteristics.
