Quantitative and qualitative appraisals were carried out in order to have proper understanding of the aquifer system and ensure sustainable development by using geophysical, geological and pumping test data obtained from 32 producing boreholes across the entire LGA. Hydraulic conductivity, transmissivity and storativity values were computed, piezometric surface map and the basement relief map were prepared, geoelectric layer characteristics were delineated and two geological profile sections were constructed. The hydraulic conductivity values were found to range from 0.021 m/day at Walijo to 1.391 m/day at Iddah-Hanya with an average of 0.42 m/day. The transmissivity values ranged between 0.90 m ² /day at Walijo to 25.37m ² /day at Iddah-Hanya, with average value of 6.31 m ² /day. Storativity values were lowest at Walijo with a value of 89.42 and highest at Iddah- Hanya having a value of 2877 with an average of 929.82. The lowest values of these three aquifer Original Research Article
