Dumpsite Characterisation in Ekpoma from Integrated Surface Geophysical Methods

Journal Title: Physical Science International Journal - Year 2017, Vol 15, Issue 4

Abstract

Foreseeable consequences of the practice of solid waste disposal in landfills are gas and leachate generation due primarily to microbial decomposition, climatic conditions and refuse characteristics. Hence, this paper presents an assessment of the effects of waste dumpsite using Electromagnetic and electrical resistivity methods in dump located along Police Barrack Road, Ekpoma in Esan West Local Government Area of Edo State. Low Frequency - Electromagnetic (VLF-EM) field data were obtained in four traverses measuring 70 m, 70 m, 40 m and 45 m at profiles 01, 02, 03 and 04 respectively. The VLF-EM data were analysed through qualitative interpretation of the curves and analysed using Karous-Hjelt Software to delineate the conductive and non-conductive zones in the study area. Four Vertical Electrical Sounding (VES) stations were utilized, using Schlumberger configuration. Data obtained from the VES technique were processed using IP2win software. The VES curves obtained revealed simple subsurface geology with characteristic H and A curve types with low resistivities in the range of 37.21 Ωm to 44.9 Ωm indicative of leachate contamination. The VLF technique revealed lithology with high amplitudes in the region of 35 m and 40 to 45 m, 21 to 30 m and 17 to 24 m also indicative of contamination arising from leachate wastes and underground pollution in the dumpsites.
