Abstract: The study seeks to evaluate potential environmental impact on surface and groundwater as well as aquifer protective capacity to suggests possible solutions in some section of Kaduna Millennium City. A total of thirty Vertical Electrical Soundings (VES) were carried out using Schlumberger electrode configuration with current electrode spacing of a maximum of 200 m. The Interpreted data revealed the weak aquifer protective capacity zones which were found in some parts of northeast and central parts (VES stations A4, A5, A6, B4, C3 and C4) with its longitudinal conductance range from 0.114 – 0.194 Ω-1 which represent 20% of the study area. Average/good aquifer protective capacity zones has longitudinal conductance ranging from 0.210 – 0.559 Ω-1. These zones covered twenty-four (24) VES stations which represent 80% of the study area and it is characterized with high thickness and low resistivity values of the weathered and fracture basement. Hence recommended for borehole siting. Similarly, the aquifer deep zones where the adjourning rocks are highly resistive (VES stations A1, A2, A3, B1, B2, D2, and E3) were also determined for siting waste and sewage disposals. However, the work also suggests that the urban associated development programs due to anthropogenic activities should be properly planned to avoid areas that are prone to contamination.
