Abstract

The recent increase in population and industrialization in Lokoja, Southwestern Nigeria has led to a corresponding increase in the quantity of waste generated and consequences on the quality of the environment. Thus, this research investigated the geotechnical and water quality attributes of a designated waste dumpsite at the Felele area for its suitability on a waste disposal site. Fifteen soil samples were obtained from the trial pits and boreholes for geotechnical analysis while ten water samples were taken within and outside the dumpsite for possible presence of heavy metals contamination. The control water samples showed no evidence of pollution while the leachate possessed a high concentration of physical parameters beyond the WHO and NAFDAC recommended permissible limits. Geotechnically, the samples are essentially sandy and gravelly with low clay content. The high permeability -5-7 values (1.40×10 – 9.46×10 m/s), large grain sizes, poor compaction properties and proximity to the highway make the site unsuitable for the development of sanitary landfills.
