Description A study of cadmium (Cd), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn) concentrations in the Spokane River was conducted. Samples were collected on eight occasions between July 1992 and September 1993. Three locations were sampled between river miles 63.5 and 96.0. Dissolved, total, and total recoverable metals were analyzed. Water quality criteria for dissolved Zn were not met at all three sampling locations during high and low flow seasons. Criteria for dissolved Pb were exceeded at all sampling sites during the high flow season. Criteria for Cd were exceeded in the upper river during the high flow season.
