Trichloroethylene (TCE), Brownfield, and Vapor Intrusion Information

Per DHS and DNR, trichloroethylene (TCE) is a human-made chemical that is not found naturally in the environment. TCE can get into the environment from spills and improper disposal.

TCE is a solvent used to remove grease from metal parts, clean fabrics in commercial dry cleaners, and other industrial processes. In homes, TCE can be found in some aerosol cleaning products, paint removers, spray adhesives, carpet cleaners, and spot removers.

People can be exposed to TCE from air, direct contact, and drinking water. High levels of TCE can affect the kidneys, liver, lung, and immune system and may cause heart defects in unborn babies. It is also a known carcinogen.

What is a vapor action level (VAL)? A VAL is the level for a contaminant when steps should be taken to quickly reduce the chemical vapors because of the potential for short-term health effects. The VAL for TCE is 2.1 micrograms per cubic meter (µg/m3).
