Groundwater is a critical resource in Illah, Delta State, where surface water is unreliable. This study aims to evaluate groundwater potential and aquifer properties using geoelectric methods, with a particular focus on Dar-Zarrouk parameters. Thirteen Vertical Electrical Sounding (VES) surveys were conducted using the Schlumberger array. Derived parameters, including resistivity, thickness, and Dar-Zarrouk indices, were analysed to characterise the aquifers’ hydraulic properties. Four to five geoelectric layers underlie the study area. Aquifer resistivity ranged from 124–2499 Ω·m, thickness from 3.4–57.9 m, and transmissivity from 27.54–468.99 m²/day. VES 4, VES 1, and VES 7 were identified as high-potential sites. Longitudinal conductance …
