Abstract

Surface geophysical survey was conducted around Aarada refuse dumpsite, Ogbomosho, Oyo State, Nigeria to locate leachate plumes migration pathways using the very low frequency electromagnetic and vertical electrical sounding techniques. Eight VLF-EM profiles of length 70 to 150m with 10m interstation spacing and seven Vertical Electrical Soundings with current electrode separation varying from 150 to 200m were established. The analyzed VLF-EM data revealed the presence of conductive pollutants (leachate plumes) at the subsurface while the geoeletric sections generated from the processed VES data showed that the leachate plumes have actually migrated to a depth of 5.4m in the area which confirmed the VLF-EM results
