|Description||The Department of Ecology surveyed sediment conditions throughout the Eastern Strait of Juan de Fuca and compared them to conditions from a similar survey. Sediments were analyzed to determine:
• Concentrations of potentially toxic chemicals.
• Degree of response in laboratory tests of toxicity.
• Condition of sediment-dwelling invertebrates.
None of the sediment quality indices changed significantly from 2002-2003 to 2013 in the Strait. Although the Chemistry Index met the Puget Sound Partnership (PSP) target value of 93.3, the overall sediment quality, as measured by the Triad Index, did not meet the PSP target of 81 in either 2002-2003 or 2013.
Appendices B, C, D, and E are available in the Win Zip file above.
