The Wisconsin Department of Natural Resources (DNR) launched a new webpage to help local governments address vapor intrusion in their communities.

The Vapor Intrusion for Local Governments webpage at dnr.wisconsin.gov/topic/Vapor/LocalGovtResources.html provides tools and resources for local governments to address vapor intrusion in their communities, including information on locating contaminated sites, considerations for development or redevelopment, vapor intrusion prevention and planning resources, as well as health information.

“The risk from vapor intrusion is new territory for many municipalities and local health departments,” said Jennifer Borski, Remediation and Redevelopment Program Vapor Intrusion Team Leader. “This webpage is designed specifically for the unique needs of local municipalities as they incorporate consideration of this health risk into their daily work on items such as permitting, redevelopment, road work and planning.”

Vapor intrusion is a phenomenon through which vapors from volatile organic compounds (VOCs) from chemicals used in commercial activities – dry-cleaning chemicals, chemical degreasers and petroleum products like gasoline – enter a building, typically through cracks or gaps in the foundation. These VOC vapors are often colorless and odorless and bring chemicals into the indoor air, which can cause unsafe indoor air quality conditions and result in adverse health effects to building occupants.

The DNR welcomes feedback on the vapor intrusion webpage improvements. Ideas and suggestions can be sent to [email protected].
