Dow Chemical Co. to test another 170 properties in Midland for dioxin

The Dow Chemical Co. will expand its dioxin testing to 170 more residential properties in Midland (MI) to try to confirm the boundaries of aerial pollution that was spread in some areas of the city as a result of historic waste management practices.
Dioxins are toxic byproducts from industrial processes that were emitted from Dow’s Michigan Operations site in Midland.

Dow and the Michigan Department of Environmental Quality agreed to a cleanup process in 2012 that targeted 1,475 properties in a designated resolution area. Dow offered homeowners free soil sampling to see if levels of dioxin surpassed a site-specific dioxin action level of 250 parts per trillion. If soil levels were higher than 250 ppt, the property owners were offered the removal of 1 foot of soil, replacement top soil and new landscaping at no cost.
Now, Dow and the MDEQ have agreed to test another 170 properties just beyond the edges of the original resolution area.
“It will serve as a way to confirm whether the original boundaries were correctly drawn and we’ll decide how to move forward from there,” Dow spokesman Nate Kerns said.
