Geoelectric Investigation of Groundwater in Some Villages in Ohafia Locality, Abia State, Nigeria

Geoelectric investigation for underground water in some part of Ohafia was done using the Vertical Electrical Sounding (VES) method. Twenty vertical electrical sounding data were acquired within the locations in the study area. These were used in delineating the geoelectric sections. The study was carried out using the Schlumberger electrode configuration and computer-aided Resist software method of interpretation was adopted. The interpretation of the VES data obtained from the study area within the geology terrain often referred to as sedimentary environment indicates that the area around VES stations 12, 13, 10 and 8 have been chosen as the most viable locations for the development of a water borehole for groundwater resources in the study area. The thickness and resistivity of the aquifers at these VES stations, which shows very good potential for groundwater, indicates that VES 12 has the highest aquifer thickness depth of 494.9m. The geologic sections of some VES stations were delineated and this also corroborated with the geological description of the area.
