Investigating Groundwater Contamination Using Vertical Electrical Sounding and Physio-Chemical Analysis around Angwan Jukpa Municipal Solid Waste, Minna, North-central, Nigeria

Abstract

The work investigated groundwater contamination in the study area using Vertical Electrical Sound technique and Physio-chemical analysis of soil and water samples within the vicinity of the Site. ABEM Terrameter SAS 4000 was used to carry out the geophysical survey. The VES data were plotted as pseudo and resistivity-sections so as to reveal the spatial distribution of the contaminant plumes. The interpreted VES data observed in the dump showed contamination plume as low zone with resistivityvalues between 1-20.5Ωm from the surface extending to a shallow aquifer of 5.8m, while the VES observed at the area free of waste dump showed a resistivity values of 174-178.5Ωm from the surface to the aquifer which is free from being polluted. The Physio- chemical analysis of soiland groundwater showed elevation in some of the parameters.
