Chicago Heights Boulevard Site in St. Louis County, Missouri
The Chicago Heights Boulevard Site involves a contaminated groundwater plume located in an unincorporated area of north St. Louis County, Mo. At some time before 1988, an unknown quantity of the industrial chemical trichloroethylene (TCE) was released at an industrial property located at 9970 Page Avenue, just northwest of the Elmwood Park neighborhood, and traveled through the soil and into the groundwater. Since then, TCE and other contaminants have been detected in groundwater beneath the residential area of Elmwood Park, and TCE vapors have been detected at levels of concern in some of the residences situated adjacent to the industrial site.
EPA is working with PerkinElmer, the current owner of the industrial site, to address vapor intrusion from TCE in groundwater at homes in the Elmwood Park neighborhood situated near the industrial site, and to address contamination at the site.
