Map shows where Michigan DEQ is investigating vapor intrusion

Michigan environmental health regulators are asking for $4.9 million to staff-up and buy more equipment to address an influx of toxic vapor intrusion sites that began last year and is expected to escalate.

Vapor intrusion is a public health hazard caused when poisonous gases from soil and groundwater pollutants migrate through porous soils or underground piping corridors and enter poorly-sealed buildings.

The Michigan Department of Environmental Quality estimates there may be as many as 4,000 sites statewide where known spills of volatile organic compounds or petroleum has created the potential for vapor intrusion.

Gov. Rick Snyder's 2018 budget proposal recommends using general fund money to develop a joint DEQ and Department of Health and Human Services (DHHS) program to respond to a growing number of vapor intrusion sites. In the past year, the DEQ took some level of action at more than 40 sites.
