1,4-Dioxane is a suspected human carcinogen and a contaminant of “emerging concern” for the EPA.  It has been found in over a thousand public water supplies across the country, including thirty in Michigan.  Will those who’ve been exposed to Ann Arbor’s contaminated groundwater develop health issues?  It’s a question that may be of concern far beyond our borders, and the focus of our report in "The Green Room."

For over ten years, the cleanup criterion for 1,4-Dioxane in Michigan has been 85 ppb.  This is in spite of the fact that in 2010, the EPA in recommended 3.5 ppb as the screening level for a one in 100,000 cancer risk. Finally, the Michigan DEQ has proposed a safer limit:  7.2 ppb.  Today—Earth Day—WEMU’s “The Green Room” looks a how this may affect Ann Arbor’s groundwater cleanup.
