| Abstract | Long Description |
A plan is described for obtaining metals and ancillary water quality data on the impact of small-scale gold dredges operating on the Similkameen River, a tributary to the Okanogan River in North Central Washington State. The metals of interest are arsenic, copper, lead, and zinc. Approximately 70 samples of dredge effluents, the dredge plume, and ambient river water will be collected. Clean sampling techniques and low-level analytical methods will be used. |
