| Short description: |
The Colbert Landfill Superfund Site is located approximately 2.5 miles north of Colbert, Washington, and approximately 15 miles north of Spokane, Washington. Contaminants of concern in groundwater are specific volatile organic compounds (VOCs): 1,1,1-Trichloroethane (TCA), 1,1-Dichloroethene (DCE), 1,1-Dichloroethane (DCA), Trichloroethene (TCE), Tetrachloroethene (PCE), and Methylene Chloride (MC). There have also been low levels of 1,4-Dioxane observed in groundwater. The groundwater remedy includes a pump-and-treat (P&T) system as well as components of landfill post-closure (e.g., landfill cap, landfill gas system) that serve to reduce contaminant source loading to groundwater over time. The remedy has also included the provision of an alternate water supply to impacted residents plus institutional controls. The RSE provides an opportunity for an independent third-party review of these remediation efforts (October 2010, 80 pages).
