Description This report covers results from 27 years of sampling sediments and benthic invertebrates at 10 long-term stations throughout the greater Puget Sound area every year from 1989 through 2015. These 10 stations represent different habitat types and distinct benthic communities. Overall characteristics of, and trends in, the habitats, sediment chemical contaminants, and benthic invertebrate communities, as well as relationships between them, are presented. Results are placed in context with broader-scale bay and region sediment monitoring results.

Although there were significant increasing or decreasing trends in a few parameters at a few stations, the most common pattern was lack of consistently increasing or consistently decreasing temporal trends. Little to no relationship was found between invertebrates and measured sediment contaminants. Sediment chemistry patterns were generally consistent with those observed at wider spatial scales. Changes in benthos seen at wider spatial scales were generally not found at the long-term stations.
