Title: Ground conductivity and magnetic susceptibility mapping of Municipal solid waste deposits: A case study of the Asawase waste deposit site
Authors: Attitsogbui, Godwin
Issue Date: 11-Jul-2015
Abstract: Leachate resulting from the seepage of rain water into waste deposit can infiltrate and pollute the water table. The areas near the Asawase waste deposit site have a greater possibility of groundwater contamination because of the potential pollution sources of leachate originating from the solid waste deposit. Magnetic susceptibility and electrical conductivity measurements were carried out on six (6) traverse lines at the Asawase waste deposit site to evaluate possible infiltration of leachate flow. The magnetic susceptibility results showed that the central and south-eastern part of the area recorded very high concentration of ferrimagnetic materials in the top 100 mm of the land surface (713-920 10􀀀6 SI). There are also traces of high probable ferrimagnetic concentrations in the north-eastern end. Results from the apparent electrical conductivity indicate that the moderate electrical conductive zone at a depth of 30 m underlying a high electrical conductive zone at a depth of 7.5 m is mapped in the north-eastern part. These two zones are underlaid by higher electrical conductive zone at a depth of 60 m. The subsurface of the east through to the south-eastern part of the area lies in a region of low to moderate apparent electrical conductivity and the direction of leachate flow is in the NE direction and very severe at a depth of 45 m.
