Hide details for Site DescriptionSite Description

The Vancouver Water Station #1 site, located at East Reserve and Northeast Plain Boulevard in Vancouver, Washington, is one of the well fields that supplies drinking water to the city of Vancouver. Vancouver Water Station #1 is the largest of Vancouver's operating well fields and is located in a municipal park called Waterworks Park. Ten wells pump as much as 20 million gallons of water per day during peak periods to supply drinking water to the residents of Vancouver and Clark County. In 1988, the city of Vancouver discovered low levels of tetrachloroethylene (PCE) and other volatile organic compounds (VOCs) in some of the wells at Station #1. In 1992, the concentrations of PCE in some individual wells exceeded the federal drinking water standard for this chemical.

Site Responsibility: This site is being addressed through federal actions and local actions.

Hide details for Cleanup ProgressCleanup Progress

Early Actions: EPA conducted initial site inspections in 1990 and 1991, which included taking soil gas measurements at businesses near the site. The source of contamination was not found. In response to increasing levels of contamination, the city of Vancouver began pumping wells and designing a groundwater treatment system. Five air stripping towers were built and began removing contaminants from the groundwater in the summer of 1993. The city of Vancouver continues to operate the groundwater treatment system.

EPA signed a Record of Decision for this site in September 1998, to continue operation of the existing air stripping treatment system. In the ROD, the site was designated as construction complete. This signifies all remedies required for the site have been implemented.

The Second Five Year Review was conducted and completed in September, 2008. This review determined that the remedy remains protective of human health.
