In this study, we report on the analytical assessment of heavy metals contents ofsoils collected from different dumpsites in Wukari and environs. The levels of Cu, Cd, Pb,Fe and Zn metals were determined and the data obtained was subjected to pollutionevaluation methods such as contamination factor (CF) and pollution load index (PLI). Thecontamination factors (CFs) revealed a moderate to extreme contamination of the dumpsitesand a decreasing trend in the heavy metals concentrations was observed in soils collected atabout 100 metres from the respective dumpsites which indicated some leaching of the metalsfrom the dumpsites to adjacent environment. The pollution load index (PLI) showed thatsome of the dumpsites are severely polluted as the PLI of the metals from each sample siteexceeded the PLI of the background (control) sample (0.2). Spearman’s rank correlationanalysis showed clear correlations (psourc
