What's New?

Updated October 2011

New Facility Begins Treating Contaminated Groundwater

The groundwater extraction and treatment system at the Bountiful/Woods Cross Superfund Site, Operable Unit 2 has been constructed and is operating. The system is designed to treat 33,000 gallons of groundwater per day emanating from a dry cleaning facility. Construction of the groundwater treatment system began in July 2010 and was completed in February 2011. Water treatment began continuous operations on February 11, 2011. As of September 30, 2011 the system has treated approximately 23,311,000 gallons of contaminated groundwater. The treated water is placed into beneficial use in a wetlands mitigation project.

The American Recovery and Reinvestment Act provided the resources for the long-term protection of human health and the environment by providing funds to build a facility to clean up a contaminated aquifer that supplies 33 residential water wells used for domestic purposes. American products were used to build the water treatment system, thus complying with the "Buy American" provisions of the act. As a result of this project, approximately nine full-time employee jobs were created. In addition to the increased employment, the local economy benefited from spending on equipment rentals, fuel, materials, food and employees' lodging. To date EPA has been invoiced for $4.4 million.

In September, to celebrate finishing the construction of the water treatment plant, the public and local officials were invited to an open house and tour of the water treatment facility. Staff was also available to discuss the sampling results mailed out to residents who had had their wells sampled. A new method for reporting sampling results using color coding to help explain what the sampling results meant had been used. We wanted to receive feedback as to whether it was any easier to understand the results.

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; OU2 covers 400 acres and is called Bountiful Cleaners, Inc.

Hatchco Property (OU1)

OU1, commonly know as the Hatchco property, 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. The 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:

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

OU2: Bountiful Cleaners Inc.

At OU2, EPA and UDEQ completed the design to treat and minimize expansion of the PCE contamination in groundwater. On June 23, 2010, EPA mobilized to the site to construct the remedy for OU2 consisting of a groundwater extraction and water treatment system. Construction began during the spring of 2010.

  • July 2005: Remedial Investigation completed 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
  • September 2007: Record of Decision for OU2 signed
  • April 2008: public availability session held
  • April 2009: public briefing held
  • August 2009: public availability session held
  • September 2009: remedial design completed for OU2
  • Summer 2010: remedial action for OU2
  • April 2011: completed physical construction of the water treatment system

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 Repository located at the Davis County Library, South Branch, and also at EPA and UDEQ offices. Site Documents can also be viewed on this Web page.

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

EPA will determine the specific ICs later in the cleanup process, following the remedial action.

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

This site has not yet approached the five-year review process. The first five-year review is scheduled for 2013.
