Site Description
The 64-acre Broderick Wood Products Site (the "Site"), in Adams County, Colorado is a former treatment plant that used creosote and pentachlorophenol (PCP) to treat wood products. In 1983, EPA detected PCP in soil and groundwater samples taken both on and off the Broderick Wood Products property. The Agency placed the Site on its National Priorities List in September 1984.
Contaminants of concern are polynuclear aromatic hydrocarbons (PAHs), PCP and their byproducts, dioxins and furans (flammable liquids). Swallowing or inhaling the contaminants can possibly cause damage to organs, irritation of the upper respiratory tract and eyes, and irritation or inflammation of the skin.
Site Risk
| Media Affected | Contaminants | Source of Contamination |
| Soil, surface water, groundwater, sludge, liquid waste | Polynuclear aromatic hydrocarbons (PAHs), PCP byproducts, dioxins and furans | Wood treatment products |
Cleanup Progress
These cleanup activities have been completed either by EPA or the potentially responsible party, Broderick Investment Company (BIC):
- Removal of sludges from the two former impoundments to a reclamation facility in 1993.
- Construction of a land-treatment unit (LTU) for contaminated soils in 1994.
- Construction of a treatment plant to treat contaminated groundwater in 1994 (modified later in 1996).
- Construction of a bioventing system to treat the subsurface area in 1996.
Current Operation & Maintenance (O&M) activities conducted by BIC include operating the groundwater treatment plant, operating the LTU to treat soils, and monitoring groundwater throughout the Site. A Five-Year Review completed in September of 2006 indicates that the current remedy protects human health and the environment for workers and people near the Site. However, more data are needed to fully evaluate the groundwater remedy.
Community Involvement
Notices were placed in local newspapers indicating that the 2006 Five-Year Review was in progress.
