I.B Osazuwa1 2Applied Science Department, College of Science and Technology, Kaduna Polytechnic, Kaduna, Nigeria ABSTRACT Resistivity and induced polarization imaging was conducted at an operational municipal solid waste - disposal site in Kaduna metropolis (north nentral Nigeria) with the aim of investigating groundwater contamination as a result of leachate accumulation.Ten survey profiles were laid around the perimeter of, as well as outside the waste disposal site to map the contaminated zones and to investigate the subsurface features responsible for the migration of the leachate. The survey was performed with multi channel (42) ABEM Field equipment. Interpreted resistivity/induced polarization models from survey profiles at the margins of the dump showed a contamination plume extending below the groundwater table while water quality analysis from existing hand dug well near the dump showed elevations in pollutant concentrations exceeding the permissible limits. There is a strong correlation between the geophysical measurements and the physiochemical analysis. Migration of the contaminants is believed to be through interconnected pore spaces which are evident from the characteristics of the conductive nature of the geo-electric layers.
