Hide details for Site DescriptionSite Description

The Bonneville Power Administration Ross Complex (BPA) site has occupied this 200-acre site north of Vancouver, Washington since 1939. The facility became part of the Department of Energy (DOE) when the department was established. The Ross Complex serves as the control center for the generation and transmission of electricity throughout the Pacific Northwest. The site contains a number of storage and disposal areas including the DOB-1 Drainfield, where laboratory wastes were deposited; the Cold Creek Fill Area, where soil contaminated with oil, polychlorinated biphenyls (PCBs), and heavy metals were disposed of; and the Fog Chamber Disposal Area, where capacitors containing PCBs were buried in trenches. In 1987 and 1988, BPA sampled an on-site well and found volatile organic compounds (VOCs). Approximately 105,000 people in Vancouver obtain drinking water from public wells located within three miles of the site. Cold Creek is approximately 450 feet downgradient of the complex and is fed by shallow ground water flowing under the site. Vancouver Lake, located 1- miles away, is used for fishing and other recreational activities.

Site Responsibility: This site has been addressed through Federal actions.

Media Affected: Groundwater & Soil
Investigations revealed that out of 21 potential waste units identified at the site, only four areas contained soil contamination at levels that required cleanup action. PCBs were found in surface soils at the Capacitor Test Lab and the Ross Substation and Capacitor Yard, and polycyclic aromatic hydrocarbons (PAHs) and pentachlorophenol (PCP) were found in surface soils at the Wood Pole Storage Area East. The Fog Chamber Dump contains high levels of PCBs and heavy metals, such as lead, throughout the subsurface soils; however, the area has been capped to ensure contaminants do not migrate further. One on-site deep ground water monitoring well slightly exceeded the drinking water standards for dichloroethylene (DCE) and chloroform. Results of the site risk assessment indicated that exposure to either on- or off-site ground water would not pose a risk to human health.
