The present work aimed at estimating Aquifer Parameters within the Taraba State University Campus using electrical resistivity method. A total of 15 Vertical Electrical Sounding (VES) data were collected using Schlumberger Configuration in a basement terrain in Taraba state university Jalingo. The data obtained were analyzed with IX1-D v.3 Interprex software. The Hydraulic conductivity and Transmissivity determine from empirical relationships range from 33114 m/day to 314113m/day and 41937.38m2/day to 696891.35m2/day respectively. Three groundwater potential rating were defined based on the aquifers Hydraulic conductivity and Transmissivity data; poor (45%), fairly good (35%), and good (20%). Vertical electrical sounding revealed that the area is characterized by 4-5 and 6 subsurface geo-electric layers with the 6- layer type being the dominant type. Longitudinal unit conductance of the overburden units ranged from 2285mΩ to 642 mΩ. It was observed that areas of good groundwater potential also have good aquifer protective capacity. Groundwater development should therefore be concentrated more in areas of good groundwater potential for continuous and steady supply of potable water.
