Total heavy metals concentrations for Cu, Pb, Zn, Mn, Ni and Fe were evaluated in soils and surface water. Samples collected from two different mine sites A (old mines) and B (new mines) analyzed using Atomic Absorption Spectrophotometer. From the analysis, it was observed that except for Cu and Fe, at 50-100m from source, total trace metal concentrations were higher at the mines location B than in the mines location A. Cd was not detected, except in surface water samples after extraction with APDC/MIBK. Based on the findings, concentrations of these metals were above the limits specified for agricultural soils, except Cu, which was within the limits. The results also revealed that the concentrations of these metals in surface water samples were above the recommendation limits of World Health Organization (WHO) for drinking water.
