Fruit Valley Neighborhood – Cadet and Swan Cleanup – Opportunity for Public Comment July 13 – August 11, 2023

The Port of Vancouver is providing this update of our progress to cleanup groundwater contamination in the vicinity of the Fruit Valley Neighborhood. We have been working under the oversight of the Washington State Department of Ecology (Ecology) to cleanup groundwater contamination associated with the Cadet Manufacturing and former Swan Manufacturing Company (Swan) sites. Groundwater cleanup has been very successful, and the Port of Vancouver has submitted a draft plan for final cleanup of these sites located near the Fruit Valley Neighborhood. The locations of these sites are shown below.

Background Information

Although contamination occurred many years before the port owned the properties, cleanup of the Cadet and former Swan sites is a top priority for the Port of Vancouver. The contamination is related to the use of solvent-based cleaning products at the sites by previous operators. Cleanup has been ongoing with oversight from Ecology since 1998, and these efforts have been very successful.

Cleanup actions have included:

  • Soil cleanup
  • Groundwater cleanup
  • Residential indoor air cleanup


Sitewide Groundwater Cleanup

The port constructed a groundwater pump and treat system that began operating in June 2009. The system pumps groundwater that’s still contaminated after completion of the other cleanup actions summarized above, and conveys it to a nearby treatment system. Treated water is then discharged to the Columbia River consistent with state and federal environmental regulations. Since June 2009, the system has:

  • Extracted and treated 14.9 billion gallons of groundwater
  • Removed approximately 1,325 pounds of contaminants

Pump and treat system located at Port of Vancouver cleans contaminated groundwater in Fruit Valley neighborhood


The 2022 data indicate that the treatment system and other actions have cleaned up the shallow groundwater under the Fruit Valley Neighborhood. Shallow groundwater contamination is now confined to a small area under the former Swan property (see the map above).

Ecology would like your comments on the proposed final cleanup plan!

The Washington Department of Ecology invites your comment on cleanup documents for the Port of Vancouver NuStar Cadet Swan cleanup site (Site). Ecology is holding a comment period from July 13 to August 11 for public review of cleanup documents for the site. The site is in Vancouver, WA.

Ecology is entering into a legal agreement called an Agreed Order (AO), DE 21295. The agreement is between Ecology and the Port of Vancouver (Port) to clean up contamination at the Cadet Manufacturing and Swan Manufacturing portions of the Vancouver Port of NuStar Cadet Swan site (Site). The Port of Vancouver is the potentially liable person (PLP) at the Site responsible for the cleanup under this AO.

Cleanup documents for review and comment during the comment period:

  • Remedial Investigation (RI) Reports
  • Feasibility Study (FS)
  • Draft Cleanup Action Plan (dCAP)
  • Draft Agreed Order DE 21295
  • State Environmental Policy Act Determination of Non-Significance (SEPA DNS)

Documents will be available prior to the July 13 comment period at our Site webpage. Please note there is another comment period running.

More information about the site and the comment period are in the fact sheet.
