Soil sample assessment was conducted on five dumpsites located within Maiduguri Metropolis, Nigeria. These includes; Bulunkutu (BLKT), Railway (RLWY), State Low-cost (STLC), Infectious Disease Hospital (IDH) and Nigerian National Petroleum Corporation (NNPC) depot. Soil samples were collected at each site while the controls were collected 10 m away from each site. Heavy metals were analyzed using AAS Perkin Elmer Model. These include; Cobalt, Arsenic, Cadmium, Chromium, Copper, Iron, Manganese, Nickel, Lead and Zinc. Physicochemical parameters such as pH, Electrical conductivity (EC) and Temperature were also determined. The mean value and Standard Deviation (SD) of the results were calculated. Most of the dumpsite soils were found to be slightly alkaline with pH range of 8.09 ± 0.04 – 8.32 ± 0.03 recorded for IDH and Bulunkutu. Pearson correlation results showed strong and significant relationship between concentrations of some heavy metals and physicochemical parameters at α=0.05 levels. Bulunkutu soil sample pH correlates strongly and significantly with the concentrations of Cd and Cu respectively. Geoaccumulation index showed moderate to strong levels of contamination, Railway and NNPC Depot dumpsites showed no trace of contamination while Bulunkutu dumpsite indicated strong Co and P contamination.
