Fresh water is becoming increasingly scarce in Taiz city, Yemen, partly due to a growing population and in part due to pollution of near surface aquifers by municipal and industrial wastes. Electrical depth sounding has been found to be powerful tool to delineate subsurface contaminated zones. The measured apparent resistivity and 1D inversion models have been used to construct apparent maps and 2D geoelectrical cross-sections displaying the variation of resistivity of the subsurface layers.

In the present study, a vertical electrical sounding (VES) was conducted using the shlumberger array at 38 sites distributed over six profiles along the most important wadis in the Uplands Wadi Rasyan, Taiz, Yemen. The objectives of this study were:(1) to locate the distribution of contamination zones, and (2) to investigate the
