The objective of the study is to evaluate the degree of stream sediments pollution around the cement factory. The heavy metals were assessed by factor and cluster analyses. Factor results revealed four sources of pollutants as explained by the four factors (84.83%) to include vehicular, effluents from factory, natural processes of dissolution/ co precipitation and ionic exchange. The R and Q- mode clusters yielded three clusters each. Also used for heavy metal assessment are, enrichment factor, contamination factor and pollution load index. EF indicates that Fe, Zn, Ni and Cd in the sediment range from depletion to minimal enrichment while in few locations Fe are moderately enriched. CF also show that the sediments have moderate contamination with respect to Fe, Zn, Ni and Cd. PLI revealed progressive deterioration of locations Obj01, Obj07 and Obj21.
