Site Type: Completed NPL City: Salt Lake City County: Salt Lake Street Address: 1967 South 700 West Zip Code: 84104 EPA ID#: UTD000716399 Site ID#: 0800596 Site Aliases: Great Western Chemical Co., Huntsman-Christensen Corp. Congressional District(s): 03 |
Site Description
In the process of making pesticides, herbicides and various chemical products, the company contaminated soils and ground water 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 ground water and ensuring compliance with institutional controls. Once cleanup goals have been met for ground water, the site will be deleted from the National Priorities List. The most recent five-year review was completed in September 2002. 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 ground water 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, ground water, soil, liquid waste, solid waste |
Herbicides, pesticides, VOCs, onsite ground water has hydrocarbons, particularly xylene and toulene |
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 1100 cubic yards of hydrocarbon-contaminated soil to break down the organic materials, thus removing the contamination (biodegradation).
- In-situ vitrification of 5600 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
EPA produces an annual update (see link below) to the five-year review, which discusses the current status of the cleanup. The next five-year review is scheduled for completion by September 2007. Community interviews will be solicited. Public comments can be sent to the EPA Community Involvement Coordinator listed below in Contacts.Site Documents
