This study was conducted to assess the extent of trace metals in Modjo tannery wastewater and their levels of contamination in the vicinity of Modjo river water and agricultural soil. Samples of tannery wastewater, river water and agricultural soils have been analyzed for Cd, Cu, Ni, Pb, Zn and Cr using atomic absorption spectrophotometry (AAS). The result showed that the concentration of Zn and Cr metals in Modjo tannery wastewater as well as Cd, Ni and Cr in the river water sample were above the standard values of FEPA and WHO. But Pb was found below the method detection limit for both wastewater and water samples. Results of one - way ANOVA shows that variations for all selected metals in both wastewater and water samples at different sampling points were statistically significant except Cd in the river water sample. For the agricultural soil sample levels of Cd, Ni, Zn and Cr were above NEQS standard limit value. The metal contamination factor (CF) also shows that the agricultural soil was highly contaminated (CF>6) with Cd and Cr, but moderately contaminated (1<CF<3) with Cu, Ni, Pb and Zn. Very high contamination factor for Cr and Cd was observed in the agricultural soil indicating that both tannery wastewater and river water affects the quality of the soil around the tannery factory.
