Exploration of Groundwater in Agulu and Environs Aniocha Local Government Area Using Electrical Resistivity Method

This study employed vertical electrical sounding (VES) to investigate the groundwater potential in Agulu and its environs. The research aimed to identify potential aquifers, determine groundwater depth and assess the geological formations influencing groundwater distribution. VES surveys were conducted at strategic locations using the Schlumberger configuration. A Vertical Electrical Sounding (VES) survey was conducted at 6 stations. The data from each station was interpreted to determine the subsurface lithology and thickness of different layers. The resulting data were interpreted using partial curve matching and computer-aided inversion techniques with Ip2win to generate 1D and 2D resistivity models. The inferred lithologies include topsoil, clay, water-saturated sand, shale, clayey sand, and sandstone. The apparent resistivity of the aquiferous unit ranging from 25.6 to 2445 Ωm and the thickness from 37 to 140.5m and the depth ranging from28 to 213m. The results of this study provide valuable information for groundwater exploration, development, and management in Agulu and its environs. The findings will aid in the siting of boreholes, wells, and other water supply infrastructure, ensuring sustainable groundwater exploitation and reducing the risk of drilling dry holes.This research contributes to the understanding of groundwater resources in the region, informing water resource management policies and ensuring access to safe and clean water for local communities.
