Findett/Hayford Bridge Road Superfund Site, Huster Road Ground Water Cleanup, St. Charles, St. Charles County, Missouri
U.S. EPA is conducting a removal action at the Findett/Hayford Bridge Road Superfund Site. Private parties under the oversight of EPA are sampling ground water in the vicinity of Elm Point Road and Huster Road to determine the levels and extent of volatile organic compounds (VOCs) which have been found in the ground water at low levels. The VOCs that are being investigated include perchloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE), vinyl chloride (VC), benzene, and others.
CURRENT ACTIONS AND SCHEDULE
As a part of the current removal action, occasional surveying, drilling, ground water testing and soil testing may be seen along Huster Road in the area just north and south of Missouri Highway 370. The field work will be done without the need for special dress or protective clothing.
Future work will involve ground water well construction during spring 2014, dates yet to be determined.
EPA, the Missouri Department of Natural Resources (MDNR), the City of St. Charles (City) and several area companies are working together to capture and remove ground water contamination along Huster Road north of Elm Point Road near Missouri Highway 370. Low levels of industrial chemicals, primarily DCE, have been found in the ground water near the City Elm Point Well field (Well field) to the south.
Regular testing and sampling confirms that the City drinking water supply, the ground water in City wells, and the drinking water treatment plant are not contaminated.
GROUND WATER AND SOIL CLEANUP
Current plans call for a contaminated ground water extraction pump-and-treat system to safely dispose, remove, and clean up the contamination. Additional investigation is being conducted in the area and, depending on the levels found, contaminated soil cleanup work may also be conducted.
WELL FIELD IMPROVEMENTS
Under the agreements with EPA and MDNR, the companies have hired engineers, geologists and construction contractors who will add two or three new medium-capacity or one new high-capacity deep drinking water supply well(s). These new wells will be added to the existing Elm Point Well field north of Missouri Highway 370 near Huster Road. The new wells will connect to the existing Elm Point Water Treatment Plant (EPWTP) with a new pipeline.
The companies will also add new shallow extraction wells in this area to remove and clean up the contaminated ground water. One will be installed north of Missouri Highway 370 along Huster Road, and one will be installed south of Missouri Highway 370 along Huster Road.
As an extra precaution, the companies will also design contamination removal equipment that may be installed in the future to remove contaminants at the EPWTP in the unlikely event that contaminants could enter City wells and reach the EPWTP.
