Site Description

The Bountiful/Woods Cross 5th South PCE Plume Superfund Site is located in southern Davis County, Utah, approximately 10 miles north of Salt Lake City and covers an area of about 450 acres. Primary land uses at the site include residential, commercial, industrial and agricultural. Secondary land uses include an interstate highway, railroad tracks, shopping mall and a petroleum refinery. This site is divided into two operable units (OUs). Operable Unit 1 covers 50 acres and is known as the Hatchco property and OU2 covering 400 acres is called Bountiful Cleaners Inc.

Hatchco Property (OU1)

OU1 is located between Interstate 15 and 800 West Street, and between 500 South and 750 South Streets in Woods Cross, Davis County, Utah. Hatchco operated as a specialized carrier of bulk petroleum and petroleum products, petroleum solvents (such as toluene and xylene), and asphalt. Also, Hatcho used its facilities to service, clean, and park tractor-trailers and tank trucks. Located on the site is a French drain where past releases of contaminated materials may have occurred and entered into the groundwater table. The primary contaminant at this site is trichloroethene (TCE). This industrial solvent was used as a metal degreaser.

Because Hatchco owned and operated at the site, EPA considers Hatchco a potentially responsible party (PRP). With EPA and Utah Department of Environmental Quality (UDEQ) oversight, Hatchco performed some of the studies that formed the basis for EPA’s cleanup decisions.

Bountiful Cleaners Inc. (OU2)

OU2, commonly known as the Bountiful Family Cleaners, was originally incorporated as Bountiful Cleaners Incorporated (BCI). The OU is bound to the north and south by 300 North and 750 South Streets and to the west and east by 500 West and 1400 West Streets. This OU is located in the cities of Bountiful, West Bountiful and Woods Cross, Utah. A dry cleaning business has operated on the site since the early 1940s and has been sold several times during that period. The release of contamination at Bountiful Cleaners Inc. likely occurred before 1967. Contamination likely occurred when wastewater from the facility was discharged into a septic system and then eventually leaked into the ground. The primary contaminant at the site is tetrachloroethene (PCE) or PERC, as it is known in the dry cleaning business. PCE is a solvent used by dry cleaners in the cleaning process.

Site Risk

Samples taken during the Remedial Investigation (RI) identified PCE and TCE contamination in the groundwater underlying the site. Located within the site's boundaries is one municipal well and several private wells that are or may become contaminated.

EPA interviewed residents to determine if well water was used for drinking and/or other household uses. The interviews determined the primary use of the well water was for stock watering and irrigation. However, in a few cases the well water is used for drinking.

Most of the domestic well water sample results showed contamination levels below the maximum contaminant levels (MCLs) considered safe for drinking under the Safe Drinking Water Act.

Media Affected Contaminants Source of Contamination
groundwater volatile organic compounds (VOCs), primarily tetrachloroethene (PCE) and trichloroethene (TCE) OU1 – wash racks, French drain
OU2 – dry cleaning process wastewater

Cleanup Progress

OU1: Hatchco Property

The remedy at the source of the TCE plume for OU1 has been implemented. Sample results show that the remedy is working better than anticipated. November 2009 sample results indicate that complete TCE treatment is occurring at almost all monitoring wells installed at the source. The results are very encouraging, considering that the same wells had high concentrations of TCE only one year ago when the first treatment was applied to the source. Additional work is being considered to address groundwater contamination west (down-gradient) of the source. OU1 completed activities:

  • July 2011: completed installing the second and third biobarriers for the down-gradient groundwater plume.
  • January 2010: remedial action start for OU1.
  • Winter 2007–2008: remedial action work for OU1 (former Hatchco property).
  • October 2007: remedial design completed for OU1.
  • Summer 2006: pilot study determining effectiveness of using enhanced in-situ bioremediation in the cleanup of the TCE plume completed.
  • March 2006: public availability session held.
  • August 2004: Proposed cleanup plan for OU1 presented to the public.

OU2: Bountiful Cleaners Inc. completed activities:

  • As of September 2011, the treatment system treated approximately 23 million gallons of contaminated water which is returned to beneficial use in a wetlands mitigation project.
  • April 2011: Completed physical construction of the water treatment system.
  • February 2011 the water treatment system began continuous operations.
  • logo of the American Recovery and Reinvestment Act
    July 2010 the American Recovery and Reinvestment Act provided the resources to begin construction of a groundwater extraction and treatment system for OU2.
  • Summer 2010: remedial action for OU2.
  • September 2009: remedial design completed for OU2.
  • August 2009: public availability session held.
  • April 2009: public briefing held.
  • April 2008: public availability session held.
  • September 2007: Record of Decision issued for OU2.
  • March 2006: public availability session held.
  • Spring 2006: soil vapor intrusion testing conducted.
  • August 2006: Feasibility Study for OU2 finalized.
  • October 2006: Proposed cleanup plan for OU2 presented to public.
  • July 2005: Remedial Investigation completed for OU2.

Community Involvement

Community involvement plays an important role in the Superfund process. EPA uses a number of different tools and resources to promote effective, on-going, meaningful community involvement. The goals of the Superfund community involvement program are to:

  • Keep communities affected by sites informed throughout the cleanup process
  • Provide opportunities for communities to comment and offer their input about site cleanup plans
  • Facilitate the resolution of community issues tied to a site

EPA and UDEQ have provided the public with information about the cleanup of the Bountiful/Woods Cross Superfund Site through fact sheets, press releases, public meetings, public notices published in the local paper and a community involvement plan. EPA and UDEQ also maintain information in the Site Information Repositories located at the Davis County Library, South Branch, and also at EPA and UDEQ offices. Site Documents can also be viewed below.

Reuse

EPA places a high priority on land reuse as part of its Superfund response program mission. The Agency tries to select cleanup options that encourage and support future use of a site. We use two fundamental methods to facilitate reuse of Superfund sites:

  • Exploring future uses before the cleanup remedy is implemented, an approach that gives the Agency the best chance of designing cleanup remedies to support the likely future use of a site
  • Working with landowners and communities to remove barriers not considered necessary for the protection of human health or the environment at those sites where remedies are already in place

One option for reuse is the siting of clean and renewable energy projects on contaminated (or formerly contaminated) lands. As part of this effort, EPA is evaluating the potential for energy projects on these properties and working with landowners and communities to identify ways to remove barriers to such projects.

Redevelopment at the site, thus far, includes the Utah Commuter Rail Parking Lot at the OU1 site. The source area, under the former Hatchco property, was developed by the Utah Transit Authority as a commuter rail parking lot with parking capacity of about 110 cars. The construction consists of asphalt pavement with concrete curbs, gutters and walkways.

Land Use Controls and Other Institutional Controls

Land use controls are the most common type of institutional control (IC). ICs are administrative or legal controls that help reduce the likelihood for human exposure to contamination. ICs can also help protect the integrity of the remedy. Examples of ICs are:

  • Zoning ordinances
  • Environmental covenants
  • Deed notices
  • Well-drilling restrictions
  • Building permits
  • Informational advisories

Institutional controls are necessary at both operable units and are in the process of being implemented. The institutional controls include:

  • Restricting groundwater use and prohibiting new well drilling for domestic use at properties located over the contaminated groundwater plumes.
  • Recommending vapor intrusion mitigation for construction of any new commercial and/or residential buildings planned on or along the projected path of the contaminated groundwater.

Five-Year Reviews

EPA or the lead agency conducts five-year reviews following the start of a Superfund cleanup when contamination is left on the site. These reviews are repeated every five years. We use these reviews to determine:

  • How the remedy is working
  • If the remedy remains protective of human health and the environment

The first five-year review was completed in 2013 and is available in Site Documents below and at the Site Information Repositories.
