WOODS CROSS/BOUNTIFUL, UT

The Five Points PCE Plume site is located in the Salt Lake Valley in the cities of Woods Cross City, Bountiful and North Salt Lake City in Davis County, Utah. The site consists of a groundwater plume of tetrachloroethylene (PCE), a chemical used as a dry cleaning agent or metal degreaser.
Woods Cross City first identified PCE in its municipal drinking water well in 1988. Subsequent investigations found that the most likely source of this contamination is a dry cleaning facility, Your Valet Cleaners (YVC), in Bountiful, Utah.
Although the plume begins in Bountiful, it travels west-southwest and most of the mile-long plume underlies Woods Cross City and North Salt Lake City. PCE is known to have been used in dry cleaning operations at YVC between 1964 and 2002 before being replaced by a liquid silicone-based dry cleaning solution.
What Has Been Done to Clean Up the Site?
The site is being addressed through federal, state and potentially responsible party (PRP) actions.
What Is the Current Site Status?
In 2008, the Utah Department of Environmental Quality (UDEQ) assumed lead responsibility for the site. Work began on the remedial investigation (RI) to determine the extent of the plume and to identify a source that may be contributing to the groundwater contamination. In March 2014, EPA approved the Final Remedial Investigation Report. Options for long-term cleanup are currently being evaluated.
Site activities have also included removal actions, or short-term cleanups, to address immediate threats to human health and the environment. Woods Cross City shut down one of its municipal supply wells because of PCE contamination. In the summer of 2007, EPA worked with a nearby dry cleaner to remove an underground storage tank and PCE-contaminated soil.
EPA placed the site on the Superfund program’s National Priorities List (NPL) in September 2007. Investigation and cleanup of the site is ongoing.
