Author(s) Toxics Cleanup Program
Description Port Gardner Bay is one of several embayments identified for focused sediment investigation and cleanup under Washington Ecology’s Toxics Cleanup Program’s Puget Sound Initiative. In early 2013, Ecology revised its Sediment Management Standards to establish a new framework for identification and cleanup of contaminated sediment sites (Washington Administrative Code 173-204). A key component of this framework was 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 of the data and regional background values for select chemicals.
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.
