Abstract

Geoelectric investigation for underground water in Obaretin – Iyanomon and its environ was done using the Vertical Electrical Sounding (VES) method. Three vertical electrical sounding (VES 12, 14 and 28) data were acquired within the locations in the study area. Borehole data were also acquired. These were used in delineating the geoelectric sections. The study was carried out using the Schlumberger electrode configuration and the Res1Dinv method of interpretation was adopted. The interpretation of the resistivity curves over the study area within geologic terrain often referred to as sedimentary environment indicates that the area have underground water potential. The experiment conducted over the area showed a total depth of 85.80 and 89.36 m respectively which corroborated with borehole data acquired from the study area. The geologic section of a nearby location termed VES 14 was delineated and its total depth was found to be 95.37 m. This also corroborated with the borehole data in the area.

Key words: Geoelectric, investigation, underground water, lithology, borehole section.
