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.
REQUEST A COPY The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
