DNR Launches New Vapor Intrusion Webpage For Local Governments

MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) today announced a new webpage to help local governments address vapor intrusion in their communities.

The new Vapor Intrusion for Local Governments webpage from the Remediation and Redevelopment (RR) Program 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. Our hope is this webpage will serve to provide readily accessible support and guidance for municipalities and encourage partnership with the DNR’s Remediation and Redevelopment Program in our shared efforts to protect the residents of Wisconsin.”

In addition to the webpage dedicated to local governments, a new landing page has been added to organize vapor intrusion resources into three main categories and provide a streamlined path to the vapor intrusion information each group needs: local governments, environmental professionals and property owners, occupants and the public.

Vapor intrusion is a phenomenon through which vapors from volatile organic compounds (VOCs) from chemicals used in commercial activities, such as 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 Remediation and Redevelopment Program welcomes feedback on the vapor intrusion webpage improvements. Ideas and suggestions can be sent to DNRRRwebrequests@wisconsin.gov.
