Vapor Intrusion Pathway

  • Contact: Abby Hendershott 616-356-0227

    Vapor Intrusion occurs when vapors from volatile chemicals in contaminated soil or ground water migrate through subsurface soils and/or preferential pathways (such as underground utilities) and impact the indoor air quality of any overlying buildings.


    The Vapor Intrusion information linked to this web page includes specific guidance developed by the MDEQ, reference materials including technical resources, training opportunities, and examples of Vapor Intrusion investigations completed within the state of Michigan. There is also a point of contact information for any questions you may have on vapor intrusion in your area.
