"Declare the Pall-Gelman 1, 4 dioxane plume a federal Superfund site." That’s the message from the Sierra Club of Huron Valley. The Sierra Club has passed a resolution urging the City of Ann Arbor and Washtenaw County to seek Superfund designation from the US Environmental Protection Agency.
The group contends that there has been little accomplished since the dioxane was first discovered in the 1980’s. A graduate student discovered the pollution being pumped into Third Sister Lake in the University of Michigan's Saginaw Forest in 1984. The chemical emanated from the Gelman Sciences facility on Wagner Road in Scio Township.
Scio Township has already passed a resolution in support of seeking Superfund designation. The city and county continue discussions on whether that’s the best course of action. Since discovery of the pollution, the plume has spread through Scio Township and parts of Ann Arbor, edging closer to the Huron River and the City of Ann Arbor’s municipal water supply at Barton Pond.
