Description The Department of Ecology Marine Sediment Monitoring Team developed the Sediment Quality Triad Index (SQTI) to facilitate calculation of the spatial extent of degraded sediments throughout Puget Sound. The index is based on combined measures of chemical contamination, toxicity, and quality of benthic invertebrate communities collected from sampling stations. The number and percent of stations, and area and percent of area, with high, intermediate/high, intermediate/degraded, and degraded sediments have been revised for sediments collected in 1997-2003 from eight PSAMP sediment monitoring regions, five strata, and Puget Sound-wide.
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.
