Description In 2012, the Washington State Department of Ecology surveyed surface sediment conditions throughout the San Juan Islands and compared them to results from a similar survey conducted with the same methods in 2002 and 2003. Sediment condition was assessed using four indices of sediment contamination, toxicity to laboratory animals, sediment-dwelling invertebrate communities (benthos), and combined Sediment Quality Triad Index. Overall sediment quality was high and remained largely unchanged from 2002-2003 to 2012.

This report gives the primary results of the 2012 survey and comparisons to the 2002-2003 survey, all of Puget Sound, and the Puget Sound Partnership's “Vital Signs” indicator targets. Data and supporting information are available on Ecology's Marine Sediment Monitoring website linked below.
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.
