The use of DC-resistivity imaging technique for mapping subsurface conditions enables to determine the different properties of material based on resistivity values. This paper presents and discusses the results of resistivity imaging investigation to identify aquifers in various rock types and thus helping in determining sites for tubular wells for groundwater exploration. The output obtained from the geoelectrical resistivity imaging showed impressive and reliable results. This study encountered several anomalous zones with low resistivity values that less than 150 ohm-m, most probably identified as fractured rock zones that have potential as the aquifer. The depth of fractured zones ranges around 20 meter to 100 meter from the surface. |
