“…By understanding the hydrogeological characteristics and subsurface geologic structures of the region, effective management strategies can be developed to ensure the long-term availability and quality of groundwater resources. Geo-electric surveys have emerged as a valuable scientific tool for assessing groundwater potential and understanding aquifer characteristics (Aina et al, 2019, Ameloko et al, 2022Raji and Abdulkadir, 2022).…”

Groundwater plays a crucial role in sustainable development. This study focuses on the challenges of potable water supply faced by the inhabitants of Shango area, northcentral Nigeria. The objective of this research is to identify suitable sites for new wells and boreholes by leveraging the geological and geoelectrical attributes of existing productive boreholes and hand-dug wells in the area. Vertical Electrical Sounding (VES) was employed to assess the groundwater potential, aquifer protective capacity and the corrosivity of the overburden units. The VES results revealed five subsurface geoelectric units, each exhibiting distinct characteristics contributing to the lithological variability of the research area. Hydraulic conductivity ranged from 0.465 to 0.534 m/day, while transmissivity varied from 9.589 m²/day to 26.029 m²/day across different VES points. Zones with thick layers and low resistivity values were indicative of high longitudinal conductivity. Regions with low protective capacity were found to be vulnerable to pollution and contamination from leaks, and waste sites. Conversely, regions with high protective capacity and sealing make groundwater pollution in such areas very difficult. Except for one VES point with low groundwater potential and limited withdrawal capacity for local water supply, the aquifers in the study area generally have intermediate designations. The study revealed that all VES points are in practically non-corrosive zones, making them suitable for burying underground tanks without extremely low deterioration rates. Based on geoelectrical characteristics, the study area was divided into three groundwater potential zones: low, medium, and high. These findings provide valuable insights into the groundwater potential and protective capacity of the Shango area, aiding in the sustainable management of water resources.
