Announcements and Key Topics

Fourth Five-Year Review Now Available!

EPA is required to review Superfund cleanups at least every five years at sites where contaminants remain in place. This year, the EPA completed its fourth review of the Wyckoff/Eagle Harbor site. The report describes the review process, summarizes progress since the last review, and recommends specific actions to improve the performance of the remedies. In the Fourth Five Year Review Report, the EPA determined that:

  • The sediment remedy in Eagle Harbor (Operable Unit 1) is "not protective" because people are exposed to contamination in the intertidal beaches on the east and north sides of the former wood treating facility.
  • The remedy for soil and groundwater in the upland portion of the former wood treating facility is "short term protective." Contaminants remaining in soil and groundwater are contained by the metal sheet pile wall around the site, and human exposure is prevented by fencing.
  • The remedy at the former shipyard (Operable Unit 3) is "protective." The cleanup actions at this property, which is now the Washington State Ferries maintenance facility, is protective of human health and the environment. The remedy is functioning as designed, and this is confirmed through annual monitoring.

Attention Boaters: Anchoring is not permitted over a large area in the eastern part of Eagle Harbor. Anchoring could penetrate the clean sand cap placed over this area in the mid-1990s, bringing contamination to the surface.

EPA’s Dive Team has been conducting underwater investigation work at the Wyckoff/Eagle Harbor site for decades. Watch our YouTube video to learn more.

Community Resources

The EPA is the lead agency for this project, but we rely on the support and cooperation of numerous other government agencies.

The Washington Department of Ecology is a key partner at the Wyckoff site. Ecology currently operates a groundwater extraction and treatment system at the former Wyckoff wood treating facility. The system helps to contain the contamination, preventing it from moving into Eagle Harbor.

The Suquamish Tribe's treaty-protected fishing area includes Eagle Harbor, and the Tribe has been working for decades to restore habitat for fish and shellfish in Eagle Harbor.

Several tribal, federal and state agencies act on behalf of the public to protect and restore natural resources in and around Eagle Harbor. These agencies, including NOAA, advise EPA on contaminant impacts and cleanup plans. They are also working to restore eelgrass in Eagle Harbor.

Attention beach goers! Contamination remains in portions of the beaches adjacent to the former wood treating plant. This fact sheet tells how to identify creosote and offers tips to stay safe.

Boaters beware! Anchoring is not permitted over a large area in the eastern part of Eagle Harbor. See our fact sheet for a map of the regulated navigation area and a list of prohibited activities.
