Mich. DEQ chief: ‘Vapor intrusion’ poses health threat

A “significant public health threat” is brewing in Michigan because of chemical vapors that percolate up from the ground of former industrial or commercial sites and can leak into nearby homes, Department of Environmental Quality Director Heidi Grether said.

Grether told lawmakers during a Tuesday budget presentation that there could be 4,000 sites in Michigan, many in Metro Detroit, where potentially harmful vapors could pose a problem to human health. She asked legislators to consider beefing up the department’s 2018 budget request by $2.6 million to dedicate eight employees to the issue full time.

“We’re concerned that this could pose a significant public health threat,” Grether said. “So we need additional staff and resources to evaluate the sites” and start mitigation projects where needed.
