Description The Sediment Management Standards establishes a new framework for identification and cleanup of contaminated sediment sites (Chapter 173-204 WAC) (Washington Administrative Code). A key component of this framework is the concept of regional background sediment concentrations, which could potentially serve as the Cleanup Screening Level for sediment sites. This final report includes a summary Ecology’s evaluation of existing data for the Lake Washington Area to establish regional background for carcinogenic polycyclic hydrocarbons.

REVISION NOTE: This report was originally published February 2017. In May 2020, we made minor copy edits to author names and updated broken links to Tables 4a, 4b, and 4c in Appendix A Data Tables. No other content was changed.
