Assessment of Leachate was carried out at five dumpsites within Maiduguri Metropolis, Nigeria. These include; Bulunkutu (BLKT), Railway (RLWY), State Low-cost (STLC), Infectious Disease Hospital (IDH) and Nigerian National Petroleum Corporation (NNPC) depot. The Leachate samples were collected at each site and analysed for metals using AAS Perkin Elmer 1000 Model. The metals assessed are Cadmium (Cd), Chromium (Cr), Lead (Pb) and Copper (Cu). The results of analyses showed that the leachate from the five dumpsites have the following ranges of mean concentrations 0.08 – 0.22 mg/cm³ Cd, 0.01 – 0.13 mg/cm³ Cr, 1.87- 2.84 mg/cm³ Pb and 1.99 – 1.99 mg/cm³ Cu. These metals are present in the leachate in low amount. Their presence however suggested that solid wastes dumpsites contribute to metals contamination of the environment.
