Abstract: This research was carried out with the aim to obtain a usable groundwater potential mapping of Afe Babalola University. Ado Ekiti. (ABUAD), using the performances rating of the drilled boreholes spread across the institution to validate an un-used groundwater potential map. Forty (40) boreholes that were drilled in the institution were subjected to evaluation and their coordinates were serially numbered and inserted into the existing Groundwater potential mapping. From the results obtained, Twenty- One (21) active boreholes were observed to have their site in locations that were designated as having good to moderate groundwater yield, Eleven (11) failed/dry boreholes had their site in locations that were considered as having good to moderate groundwater potential, Four (4) Active boreholes were also observed to be sited in area designated as having poor groundwater yield, while Four (4), were observed to be cited in areas designated as having poor groundwater yield. This results give a 66% approval rating that the groundwater potential mapping can serve as a useful guide for the purpose of site selection for groundwater exploitation.
