| Description | A Sediment Quality Triad Index was generated from data collected throughout Puget Sound by Ecology and NOAA. This index, based on sediment chemistry, toxicity, and invertebrate community structure data, was used to classify and quantify sediment quality in six monitoring regions and five strata, and for the entire Puget Sound study area. Results were also compared with data from estuaries around the U.S. While the majority of the Puget Sound study area had sediments of high quality (68%), 31% displayed some degree of degradation, while 1% was of lowest quality. Degraded sediments were found primarily in urban areas, often near biologically sensitive habitat, which may have a disproportionate impact on the health of Puget Sound biota. |
