Superfund Program Implements the Recovery Act
Wyckoff-Eagle Harbor
Bainbridge Island, WashingtonSite Description
The site is located on the east side of Bainbridge Island, WA, in central Puget Sound. The site encompasses the former Wyckoff wood-treating facility (operated from 1903 to 1988), a former shipyard, and roughly 60 acres of contaminated Eagle Harbor sediments adjacent to these former facilities. The site was contaminated with residue from the wood treating facility including creosote, pentachlorophenol (PCP) and various polycyclic aromatic hydrocarbons (PAHs). The shipyard contributed organic compounds and heavy metals to the Eagle Harbor sediments, notably mercury, lead, zinc and copper. PAHs, PCP and heavy metals have been found in ground water, soils, and sediments at concentrations that may threaten human health and the environment.
Cleanup Activities to Date
EPA added the site to the National Priorities List in 1987. To address this large site, EPA divided it into four parts called operable units (OUs): East Harbor (subtidal and intertidal sediments); West Harbor (sediments and the uplands of the former shipyard, currently the Washington State Ferries Facility); and the combined Soil and Ground water (the former Wyckoff facility’s subsurface soils and ground water aquifers). At the soil and ground water OUs, EPA expects to implement a containment cleanup approach that includes a ground water extraction and treatment system, a sheet-pile wall and a cap. To date, the ground water extraction and treatment plant has been constructed and an interim sheet-pile wall is in place.
Recovery Act Project Activity
EPA will use the up to $5 million in Recovery Act funds allocated to this site to provide continued funding to address the soil and ground water OUs. The Recovery Act funds will be used to upgrade and supplement existing ground water extraction wells and to install an additional one. The funds will also be used to demolish existing structures at the site so that the sheet-pile wall can be completed and the soil cap can be constructed. EPA projects that the entire containment remedy will be completed in five-to-seven years with assistance from the Recovery Act.
