Notes
A draft memorandum from Doug Henderson and Linda Logan to Keith Smith summarizing efforts to develop a site-specific water quality criterion (WQC) for copper in Miller, Walker, and Des Moines Creeks. The memo discusses two approaches—the Water-Effect Ratio (WER) and the site-specific metals translator—and outlines a phased approach to determine which method would be most cost-effective. It reviews the results of initial toxicity screening and range-finding studies conducted in 1999.
