An Integrated Approach To Mapping Theconcentration And Pathway Of Leachate Plumesbeneath A Dump Site In South-western Nigeria

Abstract—An integrated approach involving Electrical Resistivity Tomography (ERT), Vertical Electrical Sounding (VES), and Very Low FrequencyElectromagnetic (VLF-EM) methods has been used to map the concentration and pathway of leachates plumes beneath Laka dump site in OgbomosoSouthwestern Nigeria. In-situ analysis, specifically, Electrical Conductivity (EC) and Total Dissolved Solids (TDS) were also carried out on water samplescollected from hand dug wells, bore holes and stream around the area. The objectives of the study were to describe the  physical/hydrogeological condi-tions &nbsp…
