Superfund Program Implements the Recovery Act

Wyckoff-Eagle Harbor

Bainbridge Island, Washington

Site 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 500 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 approximately $2.4 million in Recovery Act funds to provide continued funding to address soil and ground water cleanups. 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.

FY2011 highlights include:

  • Upgrades to the existing groundwater extraction system began April 2010 and are almost complete. The completed upgrades to the existing groundwater system include the installation of new extraction well pumps. In addition, ongoing well system upgrades include the installation of pressure transducers.
  • On-site demolition work at the site began in March 2011 and was completed in July 2011.
  • Demolition work completed at the site includes characterization of wastes on site, consolidation and removal of debris piles, clearing and grubbing of vegetation, cleaning out waste from all process equipment, disposal of waste, demolition and recycling of process equipment.
  • Approximately 90 to 95% of all work is complete at this time.
