Dispersion of Metals from Abandoned Mines and their Effects on Biota in the Methow River, Okanogan County, Washington : Annual Report 3/15/00-3/14/01.
The University of Washington, College of Forest Resources and the Center for Streamside Studies in Seattle, Washington, is being funded by the Bonneville Power Administration to conduct a three-year research project to measure the watershed scale response of stream habitat to abandoned mine waste, the dispersion of metals, and their effects on biota in the Methow River basin. The purpose of this project is to determine if there are processes and pathways that result in the dispersion of metals from their source at abandoned mines to biological receptors in the Methow River. The objectives of this study are the following: (1) Assess ecological risk due to metal contamination from mines near the Methow; (2) Measure impact of metals from mines on groundwater and sediments in Methow River; (3) Measure response of organisms in the Methow River to excess metals in the sediments of the Methow River; (4) Recommend restoration guidelines and biological goals that target identified pathways and processes of metal pollution affecting salmon habitat in the Methow basin; and (5) Submit peer review journal publications. When concluded, this study will contribute to the advancement of current best management practices by describing the processes responsible for the release of metals from small abandoned mine sites in an arid environment, their dispersal pathways, and their chemical and biological impacts on the Methow River. Based on these processes and pathways, specific remediation recommendations will be proposed.
