This study employed vertical electrical sounding (VES) to delineate hydrogeological zones in the study area with the overall objective of determining the feasibility of groundwater development in Iyowa, community, Edo State. The study area is part of the Benin formation of the Niger Delta sedimentary Basin. Five VES in Schlumberger array configuration were randomly conducted in the study area. The Petrozenith Terrameter was used to conduct the vertical electrical sounding (VES) with total spread of 800m (AB/2=400). Field data were iterated using the Interpex ID software. The result indicated six (6) geoelectric sections and the main aquiferous units were delineated as unconfined and semi-confined consisting of medium sand grained, and coarse sand grained with resistivities ranging from 516.46-2603 Ωm, thickness 23.49-129.21m and depth ranging from 62.17-206.76m. The sounding curves were HAK, HAQ, AAK, and AKQ types. The recommended drill depth in the study area is 72.30m.
