dc.description.abstractGeophysical and Physico-chemical investigations of a waste dumpsite were aimed at assessing the extent of groundwater pollution arising from a leachate plume. Very Low-Frequency Electromagnetic, Resistivity Profiling, and Sounding were employed within the range of 1o100 m in NE:-SW direction, discordant with the orientation of outcrops in the area. VLF-EM results showed high range values (0 -10 µS) of conductivity within a depth range of 5-15 m. Profiling showed a low Resistivity value range (3.79 - 11.0 Ωm) within a depth range of 9 - 12 m. 'The sounding results delineated four - five vertical lithological layers from the geo-electric sections of KIT-type sounding curves. The high conductivity shown by the VLF-EM could be a signature of aquiferous layers in the area. 'The low resistivity value could be evidence of dissolved particles from the decaying rubbish in the waste, forming the constituent of the leachate. The hydro-physicochemical analysis showed concentrations of Magnesium (6.8-8.4) mg/1, Iron (2.0-3.5) mg/l, Manganese (0.5-0.85) mg/1, and lead (0.5 mg/I). Chromium (0.6-0.8) mg/I and Nickel (0.05 mg/I) were present in the water samples, higher than WIIO, 2006, and NSDQW. 2007 standards. Thus, the migration of leachate could have posed a menace of pollution.en_US
