Description In 2014, the Department of Ecology surveyed sediment conditions throughout the Admiralty Inlet monitoring region and compared them to conditions from a similar survey in 1998 and 2002-2003 (Baseline) as part of a Puget Sound status and trends monitoring program. The study area included Port Townsend and the embayments within Admiralty Inlet.

Surface sediments (top 2-3 cm) from 43 randomly selected locations were analyzed to determine:
• Concentrations of potentially toxic chemical contaminants.
• Degree of response in laboratory tests of toxicity.
• Condition of sediment-dwelling invertebrates (benthos).

The sediment contaminant, toxicity, and benthic invertebrate data were rolled up into Ecology’s Chemistry, Toxicity, Benthic, and combined Triad Indices.

Appendices A – F are available in the Win Zip file above.

REQUEST A COPY 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.
