DAYTON, OH

Superfund Site Profile

Contractors for MAHLE Behr Dayton Thermal Products LLC and the U.S. EPA are currently contacting property owners in the McCook and Old North Dayton neighborhoods as part of additional indoor air sampling needed for the agency to complete its remedial investigation.

SITE BACKGROUND

The Behr Dayton Thermal System VOC Plume site is located northeast of the confluence of the Greater Miami and Mad rivers in Dayton, Ohio. MAHLE Behr Dayton Thermal Products LLC makes vehicle air conditioning and engine-cooling systems at the site. Chrysler Corporation owned and operated the facility from about 1937 to April 2002. Groundwater beneath the plant is contaminated with volatile organic compounds, or VOCs, including the solvent trichloroethene, or TCE. Polluted groundwater from beneath the plant has migrated underground to the south/southwest through residential, commercial and industrial areas of the neighborhood. Site investigations and cleanup planning are ongoing.
