SITE DESCRIPTION

As part of Governor Gregoire’s efforts to restore the health of the Puget Sound, Ecology’s Toxics Cleanup Program is investigating sediment pollution in seven Bays.  These bays include Oakland Bay, Budd Inlet, Port Angeles Harbor, Port Gardner, Port Gamble, Fidalgo and Padilla Bays, and Dumas Bay. The goal is to locate and clean up contamination to protect and maintain sustainable use of valuable natural resources. 

Ecology chose Oakland Bay because Shelton Harbor has a history of heavy industrial use and previous studies have provided evidence of contamination.  In addition, Oakland Bay is one of the most productive shellfish growing  areas in the country. Industrial uses of Oakland Bay resulted in sediment contamination in Shelton Harbor and surrounding areas. Chemicals, woodwaste, and waste water from timber and wood product manufacturing industries have been discharged into Oakland Bay.

Previous  investigations revealed the presence of several contaminants above state standards including; metals, semi-volatile organic compounds, petroleum products and wood waste contamination. Early actions in embayments throughout the Puget Sound will contribute significantly towards overall restoration efforts. Ecology’s work will help with efforts to restore the health of the Sound by 2020.

In 2008 and 2009, Ecology’s Toxics Cleanup Program conducted a sediment study to investigate the health of the sediments in Oakland Bay. Ecology has  summarized the results of the study in the Sediment Investigation Report, which was released  for public review and comment in December 2010.  The Sediment Investigation Report contains information about:

  • Location and amount of chemicals and woodwaste in the sediment.
  • Amount of sediment movement and deposition in Shelton Harbor and Oakland Bay.
  • Potential effects of sediment contamination on the health of creatures living on or in the sediment.
  • Possible sources of dioxin found in sediment.

Ecology requested that the  Department of Health (DOH) evaluate sediment and tissue data from Oakland Bay. According to the Department of Health, it is unlikely that eating shellfish from or having contact with sediments in Oakland Bay or Shelton Harbor will harm people’s health. Read the DOH health consultation report.

 Current Status

Ecology is developing next steps for sediment cleanup.  You can download slides from our May 3, 2011 presentation for the Board of Mason County Commissioners for an overview of the sediment investigation and next steps.

Ecology is participating in an effort being led by the Squaxin Island Tribe and Simpson Timber Company to identify potential habitat improvement projects in Shelton Harbor. Ecology’s role will be to ensure that cleanup measures are included in habitat improvement plans.  For more information about habitat improvement work in Shelton Harbor:

Other Work in Oakland Bay

Ecology's Water Quality Program is currently developing a plan to address water quality problems in Oakland Bay, including fecal coliform bacteria.  For more information about this work visit http://www.ecy.wa.gov/programs/wq/tmdl/oakland_bay/index.html.

The Oakland Bay Clean Water District is a multi-agency coordinated effort to restore the health of Oakland Bay.  To learn more, visit:  The Oakland Bay Clean Water District web site.
