The Ann Arbor Environmental Commission will hear an update this evening regarding the clean-up efforts at Washtenaw County’s Gelman Sciences plume site. WEMU’s Kevin Meerschaert reports.

Michigan’s Attorney General says terms of a new consent judgment have been reached between the state’s Department of Environment Great Lakes and Energy (EGLE) and Gelman Sciences. Dana Nessel says it moves forward plans to remediate Gelman’s 1,4, toxic dioxane plume. But, as WEMU’s Cathy Shafran reports, a local activist group is questioning the plan.

Another legal battle is brewing between the city of Ann Arbor and Gelman Sciences. WEMU's Josh Hakala reports.

A consultant for Ann Arbor Township is recommending continued testing of area wells for the 1,4 dioxane emanating from the old Gelman Sciences facility in Scio Township. As WEMU's Cathy Shafran reports, that's despite the fact state testing of a local well last week did not turn up detectable levels of the toxin.
