The Environmental Protection Agency has proposed adding the former site of a refrigerator-valve manufacturing facility in Washington, Missouri, to its National Priorities List.

Superfund sites that are added to the National Priorities List are eligible for federal funding for cleanup. The former site of the Sporlan Valve Plant, operational from 1939 until 1968, used industrial chemical solvents to make refrigerator parts.

Harmful contaminants such as benzene and trichloroethylene — or TCE — remained in the soil and groundwater over several decades. Exposure to such chemicals can cause cancer and damage to multiple organs.

After years of concern, residents of Elmwood Park aren't any closer to knowing if they are being harmed by chemical vapors.

In the late 1980s, the industrial chemical trichloroethylene, or TCE, was first detected in groundwater under the North St. Louis County neighborhood. The contamination came from spills at the nearby Missouri Metals Shaping Company.
