HAMILTON & LABREE ROADS

The Hamilton/Labree Roads Ground Water Contamination Superfund Site (Site) is located near the intersection of Hamilton and Labree Roads, west of Interstate 5, about two miles southwest of the City of Chehalis in southwest Washington State. The Site includes two areas where releases of hazardous wastes are known to have occurred: the Hamilton Road Impacted Area (HRIA) (10 acres) and the S.C. Breen Construction Company (Breen) Property (11 acres). The Site also contains an area where a release is likely to have occurred called the Thurman Berwick Creek Area (west of the HRIA and south of the Breen Property). Contaminated groundwater plumes originating from these areas extend downgradient and west of Labree Road. The HRIA comprises Operable Unit (OU) 1 while the Breen Property, Thurman Berwick Creek Area, and downgradient areas outside of the HRIA comprise OU 2. The contaminants of potential concern are tetrachloroethene (PCE) and its degradation products trichloroethene (TCE), cis-1,2-dichloroethene (DCE), and vinyl chloride, as well as the chemicals tetrahydrofuron and methylene chloride. Total Petroleum Hydrocarbons (TPHs) are also considered to be a presumptive contaminant of concern until more data is collected across the Site. PCE is the primary or "indicator" contaminant at the Site. Site Responsibility: This site is being addressed through federal and potentially responsible party actions.
