Superfund Site: WYCKOFF CO./EAGLE HARBOR
BAINBRIDGE ISLAND, WA

Superfund Site Profile

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.

Summer is quickly approaching and with it, sunny weather and low tides during daylight hours. EPA and the Washington Department of Ecology want to remind the local community around the Wyckoff/Eagle Harbor Superfund site that portions of the beaches east and north of “the Point,” the site’s former processing area, are still contaminated.

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.

EPA Completes Repair of Sediment Cap in Eagle Harbor 

Workers have repaired a portion of the sediment cap on the bottom of Eagle Harbor. The repair included a new sand layer, with a rock layer on top to prevent erosion. Part of the protective cap had eroded, exposing contaminated sediments that could be toxic to marine life. Construction wrapped up in late February. Please see the fact sheet for more information (PDF) (1 pp 224 KB).

Integrating Community Priorities and Cleanup Plans
A December 2016 White Paper reflects on the Site’s history, and describes community efforts to preserve Pritchard Park and land for the Bainbridge Island Japanese American Exclusion Memorial:

Site Background

The Wyckoff Eagle Harbor Superfund Site (Site) is on the east side of Bainbridge Island in Central Puget Sound, Washington. EPA added Eagle Harbor to the Superfund site list in 1987, when environmental investigations revealed extensive contamination in soils, groundwater, and in the sediment on the bottom of Eagle Harbor. EPA divided the site into cleanup areas:

  • Eagle Harbor sediment – About 100 acres of sediment on the bottom of Eagle Harbor became contaminated with creosote and other wood preserving chemicals released from the former Wyckoff wood treating facility. Also called the East Harbor Operable Unit (OU1).
  • Wyckoff wood treating facility soil and groundwater – located on the south side of Eagle Harbor, this area includes soil and groundwater that became contaminated during decades of wood treating operations. Also called the Soil and Groundwater Operable Units (OU2 and OU4).
  • West Harbor soil and sediment – the site of a former shipyard, this area became contaminated with mercury and other metals. Also called the West Harbor Operable Unit (OU-3).

Extensive cleanup actions have been completed in all three areas. The remedy in West Harbor is functioning as designed. No further work is needed at this time.

Additional cleanup actions are needed in the soil and groundwater at the former Wyckoff wood treating facility, and in the adjacent beach sediments. EPA released its Proposed Plan, which describes the agency’s preferred cleanup alternatives, in April 2016. The public comment period on the Proposed Plan closed June 30, 2016. After we carefully consider all of the public comments received, the EPA will issue a cleanup plan in late 2017
