Fruit Valley Neighborhood – Cadet and Swan Cleanup
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 (Cadet) and former Swan Manufacturing Company (Swan) sites. Groundwater cleanup has been very successful, and the port is now evaluating final groundwater cleanup options for these sites located near the Fruit Valley Neighborhood. The locations of these sites are shown below.

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. 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 the Washington State Department of Ecology since 1998, and these efforts have been very successful.
Cleanup actions have included:
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 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:
The 2020 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).
The Port Would Like Your Feedback!
The port is now working with Ecology toward final remedy of the site including a plan for shutting down the pump and treat system. The very low levels of remaining contamination on the Swan property will degrade naturally over time, without risk to human health or the environment.
In order to properly evaluate possible remediation alternatives in its report to Ecology, the port is seeking community input on the cleanup process. Please take a few moments to share your feedback. Feedback collected from this survey will be considered as the port continues work to identify a final cleanup remedy for the Cadet and Swan sites and to ultimately make a final recommendation to Ecology.
