Geophysical techniquesis including resistivity image, vertical electrical sounding (VES), and seismic refraction have been conducted to investigate the water system. The contaminated groundwater has lower resistivity values than fresh groundwater due to the higher concentration of ions which reduces the resistivity. Resistivity image and sounding in this area clearly identified the nature of the lithological depth and proved useful at identifying water-bearing zones.
