When environmental contamination presents potential human health risks, the Wisconsin Department of Natural resources (DNR) works closely with the Wisconsin Department of Health Services (DHS) and local health departments.

In February 2022, DHS published TCE in the Workplace, a fact sheet on health concerns associated with trichloroethylene (TCE) in various work environments. TCE in the Workplace helps workers understand the health risks where TCE is being used in a facility and may be helpful during vapor intrusion investigations. It is available in English, Spanish and Hmong.

The fact sheet includes suggestions to keep workers safe, as well as workplace guidelines for exposure limits by the National Institute for Occupational Safety and Health (NIOSH), the Occupational Safety and Health Association (OSHA), the American Conference of Governmental Industrial Hygienists (ACGIH) and the DNR.

The DHS fact sheet TCE in the Air is also available to assist with communicating the health risks of TCE in situations when contamination has the potential to cause vapor intrusion in nearby structures (e.g., residences, day cares). Since publication, the DNR, DHS and environmental consultants have been providing TCE in the Air to off-site property owners to educate them about the health risks associated with TCE while working to gain access, perform vapor intrusion investigations and install mitigation systems. TCE in the Air is available in English and Spanish.

Links to the fact sheets are available under the “Health” tabs on the DNR’s Vapor Intrusion Resources for Environmental Professionals and Vapor Intrusion webpages.

Site-specific questions regarding vapor intrusion in Wisconsin should be directed to the assigned DNR Project Manager. General questions can be directed to the contacts listed on the DNR’s Vapor Intrusion Resources for Environmental Professionals webpage.
