Abstract: We assessed primarily concentrations of lead, cadmium, copper, zinc and water hardness in the Columbia River between Birchbank and Waneta. Water quality in this reach of the river is affected by discharges from municipal treatment plants and particularly Cominco Limited's lead-zinc smelter and fertilizer complex. Special emphasis was given to the comparison of lead concentrations with hardness-related Canadian Water Quality Guidelines, and the United States Environmental Protection Agency criteria recommended for the protection of aquatic life.
