Heavy metal pollution of water resources can be apprehended in East Singhbhum region which is a highly mineralised zone with extensive mining of copper, uranium and other minerals. Fish samples were collected around Bagjata uranium mining area and the heavy metal analysis was done by Atomic Absorption Spectrophotometer. The geometric mean concentration of Fe, Mn, Zn, Pb, Cu and Ni of all the fish samples was found to be 18.32, 2.34, 7.35, 1.08, 0.52 and 0.34 mgkg^{-1}_{fresh}, respectively. In general, the fish samples collected from the pond were found to have higher concentration than the rivers. The results suggest a very strong association of Fe and Mn between the water and the fish samples and Zn, Pb and Cu between sediment and fish samples. To assess the risk due to intake of heavy metals through the ingestion of fish, the hazard quotients were calculated using the USEPA method. The hazard quotients of the heavy metals were below 1 posing no threat due to intake of fish to the local consumers
