Abstract Long Description

This project is designed to assess sediment quality and, to a lesser extent, fish tissue quality in greater Elliott Bay, Seattle. Washington State Department of Ecology (Ecology) staff will collect samples of surface sediment from 30 locations. Washington Department of Fish and Wildlife (WDFW) staff will collect English sole caught in trawl samples from two areas. Most sampling will take place in Elliott Bay proper, but some will occur in waterways that border Harbor Island and in the Lower Duwamish Superfund cleanup site.

This project will focus on measuring levels of:

  • Conventionals, trace metals, PAHs, PCBs, and dioxins/furans in samples of 0-10 cm deep sediment.
  • Chlorinated dioxins and furans in samples of 0-3 cm deep sediment.
  • Chlorinated dioxins and furans in English sole fish tissue samples.

    Some sediment samples will be tested for various indicators of chemical and biological sediment quality by staff of Ecology′s Marine Sediment Monitoring Program (MSMP).

    Results from this project will augment MSMP findings. The results will also be used to estimate levels of contaminants in areas that might be deemed local area background. This will be the first sediment survey to collect data that will enable a comparison of 0-3 cm and 0-10 cm contaminant levels.

    Results from this project will add to the very limited data available for levels of dioxins and furans in English sole tissue.

    Each study conducted by Ecology must have an approved Quality Assurance Project Plan. This plan describes the objectives of the study and the procedures to be followed to achieve those objectives. After completion of the study, a final report describing the study results will be posted to the Internet.
