EPA to Repair Sediment Cap in Eagle Harbor
This month, workers will begin repairing a portion of the sediment cap on the bottom of Eagle Harbor. The repair will include a new sand layer, with a rock layer on top to prevent erosion. Part of the protective cap has eroded, exposing contaminated sediments that could be toxic to marine life. Construction is expected to wrap up by mid-February 2017.

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 2016.
