There have been several cases of rampant borehole failure within the area. Some boreholes give out poor yield at certain periods of the year; many others go dry shortly after well completion while some do not show any indication of water presence after drilling several meters of depth in the subsurface. The wasted resources added more hardship to the prevailing water scarcity and thus make life very unbearable for the people. Vertical electrical sounding (VES) technique using Schlumberger configuration was employed to carry out electrical resistivity surveys to determine the causative geological/geophysical factors that give rise to the problem. Data sets of both productive and non-productive boreholes were acquired together with global positioning system (GPS) measurements to investigate the problem of borehole failure within the study area.
