Site Description
The Sand Creek Industrial Site (the "Site") occupies about 550 acres in Denver and Commerce City, Colorado. Four sources of contamination, all now inactive, were known to exist: an oil refinery, a pesticide manufacturing facility, acid pits and a landfill.
EPA conducted sampling at the Site and found the soil and ground water contaminated with volatile organic compounds (VOCs), pesticides, herbicides and arsenic. Exposure to such contaminated ground water or soil could cause serious health problems, such as cancer and damage to the liver, central nervous and respiratory systems. People also could be exposed by inhaling contaminated dust and vapors. EPA proposed the Site for the Superfund National Priorities List (NPL) in December 1982 and added the Site in September 1983. It was deleted from the NPL in December 1996 after completion of the cleanup. Various parcels of land have recently been sold for redevelopment.
Post-Construction Activities
Current Operation and Maintenance (O&M) activities include:
- Operating the landfill system,
- Maintaining the fence around the landfill,
- Maintaining the vegetative cover over the landfill, and
- Monitoring ground water throughout the Site.
Site Risk
Results of the most recent Five-Year Review completed in September of 2005 indicated that the remedy currently protects human health and the environment.

Cleanup Progress
Cleanup Completed
These cleanup activities have been completed:
- Installation of a methane gas collection/treatment system at the landfill in 1991.
- Removal of four buildings, four rail cars, two concrete tanks and thirteen steel tanks in 1992.
- Treatment of subsurface soils, using Soil Vapor Extraction in 1994.
- Removal of oily liquids floating on ground water in two localized areas, using Dual Vapor Extraction in 1995.
- Treatment of surface soils, using Low Temperature Thermal Treatment in 1994.
Community Involvement
Community comment was solicited for the five-year review completed in September 2005. The next Five-Year Review will be completed by September 2010.
