Description In March 1989, Ecology included the Little Spokane River on Washington's 304(L) mini-list as water quality impaired due to toxics because of mercury and cyanide contamination. This assessment was based in part on Ambient Monitoring Section (AMS) mercury data for WY87 and WY88 which showed occasional mercury levels in excess of EPA's chronic criteria of 0.012 mg/L.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
