Site Description

In the process of making pesticides, herbicides and various chemical products, the company contaminated soils and groundwater at the 18-acre site, located at 1987 South 700 West in Salt Lake City.

The site was added to EPA's Superfund National Priorities List in 1991.

Current operation and maintenance activities include monitoring of groundwater and ensuring compliance with institutional controls. Once cleanup goals have been met for groundwater, the site will be deleted from the National Priorities List. The most recent five-year review was completed in September 2007. Since waste is left in place, EPA will continue to conduct five-year reviews to ensure that the remedy remains protective of human health and the environment.

Site Risk

The main contaminants of concern are herbicides, pesticides and volatile organic compounds (VOCs) (carbon-based substances that evaporate easily). Also, the onsite groundwater is contaminated with hydrocarbons, particularly xylene and toluene.

These contaminants have the potential to cause liver and kidney damage. They cause cancer in mice. Dioxin compounds can have harmful effects on human reproductive and immune systems.

Media Affected Contaminants Source of Contamination
air, surface water, groundwater, soil, liquid waste, solid waste herbicides, pesticides, VOCs, onsite groundwater has hydrocarbons, particularly xylene and toluene process of making pesticides, herbicides and various chemical products

Cleanup Progress

Cleanup Completed

The following cleanup activities were completed in 1995 and 1996 by the potentially responsible party, Entrada Industries:

  • Land farming of 1,100 cubic yards of hydrocarbon-contaminated soil to break down the organic materials, thus removing the contamination (biodegradation).
  • In-situ vitrification of 5,600 cubic yards of soil contaminated with other chemicals. The process melted the soil into vitrified (glass like) material free of organic content.
  • Installation of a groundwater extraction and treatment system.

Community Involvement

Community involvement plays an important role in the Superfund process. The 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.
