Description As part of Ecology’s Urban Bays monitoring program, Commencement Bay surface sediments were sampled in 1999, 2008, and 2014. Sediment condition was evaluated with calculated indices based on results of laboratory analyses.

Overall sediment quality in Commencement Bay has remained statistically unchanged and met the Puget Sound Partnership vital sign target for the Triad Index (a combination of the chemistry, toxicity, and benthic indices). The Chemistry Index significantly improved since 1999. However, the Toxicity and Benthic Indices showed significant decreases during the same time period.

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