Geoelectrical Evaluation of Waste Dump Sites at Warri and its Environ, Delta State, Nigeria

The existing waste dump sites in Delta State were investigated without soil disturbance by using the vertical electrical sounding (VES).The soil overlying the aquifer at Ovwian-Aladja dump site has resistively values, 11.84-85.50 Ohm-m, thicknesses,21.10-31.83m and at depths less than 1m, while at Warri it has resistively values, 160-1074 Ohm-m, thicknesses, 1.53-7.87m, and at depths less than 1m. The soil overlying the aquifers in the dump sites have been identified and the implication to the quality of the sites discussed.
