EPA to take samples and install new wells at Hamilton/Labree site
On June 11, 2014, EPA contractors will begin sampling soil and groundwater at the Hamilton Road Impacted Area, part of the Hamilton/Labree Superfund site. Drill rigs will take samples as low as 45-50 feet below the ground surface. Contractors will also install several new monitoring wells and groundwater/surface water measuring devices in the same area.
The Hamilton Road Impacted Area is a 10-acre area located along Interstate 5 and North Hamilton Road, about three miles south of Chehalis. The purpose of the sampling is to find the worst contamination so that we can better focus where to do cleanup. The new wells and devices will give additional information on groundwater flow in the area, and how groundwater and surface water interact with each other.
Work will take place Monday – Friday during daylight hours. Traffic control plans are in place, and we will make every attempt to not disrupt traffic or local businesses. We expect to complete work on or before August 15, 2014.
For more information, contact Tamara Langton at firstname.lastname@example.org or 800-424-4372, extension 2709.
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.
On August 28, 2013, we issued an interim cleanup plan, called a Record of Decision, for the Hamilton Road Impacted Area. For more information, read our fact sheet.
