The overall aim of the experiments was to evaluate the degree of contamination arising from the landfill. Resistivity data was collected from three profiles spread across the survey lines using the dipole-dipole based electrode configuration. Data was processed using RES2DIV inversion software which enables the apparent resistivity Pseudo-sections to be created. Analysis of the of Pseudo section results shows that profile one has a conductive path which penetrate to depth of 20m; profile two has very high conductive structure which extend diagonally across the study area and profile three showing a structure that is partly conductive and largely resistive as a result of closeness to fresh basement rocks. North-western boundaries of profile 2 and 3 indicated highly conductive area (HCA) and less conductive area (LCA are highly anomalous with very potential for association with leachate migration. These areas have shown various conducting path via cracks and veins so that the groundwater may have been contaminated. It is therefore suggested that geochemical analysis of the water in the identified areas be investigated to determine the extent of contamination. Also, the need to periodically monitor leachate migration process to safeguard the groundwater resources is very imperative hence it is recommended that a thorough study of any waste disposal site be carried out before the take-off operation.
