Monitoring Sediment Quality

As part of the Washington State Department of Ecology’s Urban Bays monitoring program, Commencement Bay surface sediments were sampled in 1999, 2008, and again in 2014. Sediment condition was evaluated with calculated indices based on laboratory analyses, including:

 Chemistry – concentrations of potentially toxic chemicalsdoe-study-area

 Toxicity – sediment and porewater toxicity to test organisms

 Benthic – presence of sediment dwelling organisms

 Triad – overall sediment quality; a combination of the chemistry, toxicity, and benthic indices The program is designed to evaluate and compare results over multiple surveys and over time.
