Quality Assurance Project Plan-- Sediment Contaminant Study, Klamath River Sediment Sampling Program

This Quality Assurance Project Plan documents the sampling design and quality assurance guidelines for the Sediment Contaminant Study, Klamath River Sediment Sampling Program. The study is being undertaken to inform the 2012 Secretarial Decision to either remove or retain four Klamath River dams: JC Boyle, Copco 1, Copco 2 and Iron Gate. In conjunction with toxicity studies, chemical, physical and biological analyses will help determine whether constituents may be present at harmful concentrations. This contaminant investigation will help evaluate the potential for exposing or transporting contaminated sediment should the dams be removed.
