In this research, geophysical investgatons involving geoelectric survey using ABEM SAS 300 Terrameter was carried out around three actve dumpsites in Gusau, Northwestern, Nigeria for hydro-geophysical assessment of the contaminaton of soil and groundwater. Vertcal electrical Soundings (VES) were conducted on the dumpsites by using Schlumberger array with maximum current electrode separatons of 180 m. Five VES were conducted on each dumpsite making a total of ffeen VES along three profles. The feld data obtained has been analyzed using WinGlink sofware which gives an automatc interpretaton of apparent resistvity. The VES results revealed three subsurface layers. The geologic sequence beneath the study area is composed of topsoil (clay to sandy-clay, sandy-lateritc), weathered basement, fractured basement and fresh basement.The topsoil has resistvity ranging from 1.5 Ωm to 48.2 mΩ while the thickness vary from 0.47 m to 3.37 m across the profles. The second layer's resitvity vary from 5.4 Ωm to 144.35 Ωm and their thickness ranges from 1.36 m to 16.93 m. The third geoelectric layer has resisitvity from 70.0 Ωm to 6003.0 Ωm. The results revealed that the top soils in all the dumpsites were characterized by very low resistvity depictng possible polluton and contaminaton at all dumpsites. The dumpsites are depicted by diferental decompositon of waste as zones of advanced decompositon and fresh waste are refected by low and high resistvity respectvely. The second and third layers show moderate to high resistvity values which are indicatve of leachate absence. These areas are suitable for groundwater expolraton. Findings from the study indicate that there may be possible contaminaton of shallow groundwater system in the nearest future if proper mitgaton measures are not taken into consideraton at the dumpsites. Solid wastes are produced on daily basis as a result of direct consequence of inevitable human actvites. Refuse contents consist of various kinds of materials like metallic, organic and non-biode- gradable materials [1]. The intensity of the human actvites has led to increasing volume of solid Introducton The environment has over the years faced ad- verse natural and anthropological challenges in- cluding over populaton, rapid loss of biodiversity, global warming and waste management.
