Abstract
An electrical resistivity survey was carried out at a dumpsite and controlled station located about 200m away from the dumpsite to assess the vertical extent of leachate contamination of the dumpsite and its impact on the soil and groundwater resources. Subsurface resistivity of the dumpsite and the controlled stations were examined, which reflects the subsurface soil tolerance and the impact of the vertical extent of leachate contamination on the subsurface. The leachate infiltration may reflect the state and the quality of the groundwater. This implies that leachates from the dumpsite must have also migrated into the aquifer system, thereby contaminating the water-bearing unit.
