The Wenner offset system of electrical resisitivity sounding and its multicore cable was used to carry out resistivity survey, in parts of Kaduna town and environs in the Basement Complex of Northern Nigeria. The study is aimed at preliminary appraisal of the groundwater potential of the study area. Thirteen sounding points were taken at various point of interest using Abem terrameter SAS1000.The readings were at spacings of 0.5, 1, 2, 3, 4, 8, 16, 32, 64, and 128m. The field obtained were plotted and subjected to quantitative and qualitative analysis. The layers, resistivities, thicknesses, the depth to basement, and the groundwater potential were deduced. The study area revealed four to six geoelectric layers, consisting of topsoil (laterite, sand and clay), lateritic clay, sand and clay), (sandy clay) highly weathered basement, partially weathered/fractured basement rocks units and fresh basement rock or bedrock. The highly weathered basement/partially weathered and fractured layers constitute the main aquifer unit and with varied potentials in the study area.
