Validation of groundwater potential zone based on imaging profiles using different array and lines of survey position

Two resistivity and induced polarization surveys were carried out in this study to validate the groundwater potential location. These 2D geo-electrical survey lines were perpendicular to each other and intersected at point E. The survey lines used a different array configuration; pole-dipole and Wenner-Schlumberger for AB and CD lines, respectively. The surveys were conducted using set of ABEM Terrameter SAS 400 which resulted a resistivity and induced polarization imaging profiles after an analysis in RES2DINV software. The results revealed that, both induced polarization profiles have a low chargeability values of between 0 - 10 ms at intersect point, E even though the resistivity values varied. Thus, the results have verified the location to be a highly potential groundwater reservoir. The reservoir may be found around 50 m depth below ground surface
