Description As part of Ecology’s Urban Bays monitoring program, Elliott Bay surface sediments were sampled in 1998, 2007, and 2013. Sediment condition was evaluated with calculated indices based on results of laboratory analyses.

Overall sediment quality in Elliott Bay is improving and met the Puget Sound Partnership vital sign target for the Triad Index (a combination of the chemistry, toxicity, and benthic indices). Although significantly improved, targets for chemistry were not met. Sediments were generally non-toxic, yet 30% of the sediment-dwelling communities were adversely affected.

Appendices A-F are available in the Win Zip file above.

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.
