Abstract
Electrical resistivity survey was carried out to delineate subsurface layers and to determine
the ground water potential in the study area. The study was carried out using the ABEM
SAS 1000 terrameter which worked on 16 vertical electrical sounding (VES) points within
the area. A maximum distance of 550m current electrode spread was adopted for this
survey. The result showed the presence of four geoelectric layers with the resistivity of the
first layer ranging from 25.54Ωm to 619.45Ωm and thickness of 0.14-9.21m representing
topsoil. The second geoelectric layer has resistivity ranging from 20.94Ωm to 706.82Ωm
and thickness of 2.58 to 35.36m representing laterite. The third geoelectric layer has
resistivity ranging from 12.29Ωm to 598.93Ωm and thickness of 3.33 to 58.06m
representing sandy clay. The fourth geoelectric layer has resistivity ranging from 12.1Ωm to
1980.52Ωm and thickness of 11.4 to 45m representing sand. The depth to the aquifers are
13.11m, 55.31m, 6.35m, 50.28m, 51.08m and 28.01m in VES 1, 2, 6, 9, 11 and 16
respectively.
