The Hamilton Labree Roads Groundwater Contamination Superfund Site is located near the intersection of North Hamilton Road and Labree Road, west of Interstate 5, about two miles south of Chehalis, Washington. The site was added to the Superfund National Priorities List in 2000. The site includes two areas where perchloroethylene (PCE) and other chemicals were released into soil and surface water: the S.C. Breen Construction Company (Breen) property and the Hamilton Road Impacted Area (HRIA). There are other areas at the site where releases likely occurred, including at or near the Thurman Berwick Creek Area.
Contaminated groundwater plumes flow west and northwest from these areas along the Newaukum River Valley. Most of the homes and businesses here use drinking water from the City of Chehalis public water supply system. However, if the PCE is not cleaned up and the contaminated groundwater plumes continue to advance, residents and workers not on the public water supply system may be at risk of drinking PCE-contaminated groundwater.
In April 2013, we sampled 19 residential drinking water wells along Rice and Hamilton Roads. These wells are not hooked up to the Chehalis municipal water supply line, and are downstream of the known sources of PCE contamination at the site. PCE was not detected in any of these wells.
Proposed Plan for Hamilton Road Impacted Area
