Vapor Intrusion and Residential Indoor Air
Sites with volatile organic compound (VOC)
contamination are potential public health hazards. Contact with
contaminated soil and the contamination of drinking water are widely
recognized pathways of exposure. One pathway
involves VOC movement from groundwater or soil into nearby building
foundations, and then into the indoor air that people breathe. This
pathway is commonly known as chemical vapor intrusion.
Guidance for the General Public
Fact sheet describing the vapor intrusion pathway,
how it is investigated, and what can be done if vapor intrusion is a concern
in or near your home.
Guidance for Environmental
Consultants and Contractors
The Wisconsin Division of Public Health (DPH),
Department of Health Services (DHS) has developed guidance for
environmental consultants and contractors addressing chemical vapor
intrusion questions. Basic vapor intrusion concepts are reviewed in
an effort to develop a simplified, pragmatic approach to addressing this
exposure pathway. DHS guidance is intended to compliment
regulations and policies of cleanup programs in the Department of Natural
Resources (DNR) and Department of Safety and Professional Services.
