ANN ARBOR, Mich., Nov. 15, 2021 – Last week, Scio Township officials announced the discovery of dioxane contamination in additional residential drinking water wells north of a dioxane plume at the Gelman Sciences’ site. These new test results strongly suggest that the plume is expanding and will soon impact more communities.

“For more than 40 years, our community has battled the harmful impact of this dioxane plume and worked to hold those responsible accountable,” said House Democratic Leader Donna Lasinski (D-Scio Township). “In Scio Township, we are acutely aware of the danger this poses to our community, and our local officials have taken aggressive measures to monitor the spread with state-of-the-art testing, which produced these alarming test results. Continued cooperation between local, state, and federal agencies is needed to monitor and combat this ongoing disaster.”

U.S. Rep. Debbie Dingell (D-Dearborn) recently sent a letter to Environmental Protection Agency Administrator Michael S. Regan requesting that the federal agency closely study these recent test results and factor them into their ongoing evaluation of the Gelman Sciences’ site.

Gelman Sciences was a medical filter manufacturer that caused a toxic dioxane plume with unregulated waste disposal. The dioxane groundwater plume, which is currently four miles long and one mile wide, has polluted local lakes, creeks, residential drinking water wells, and a Ccity of Ann Arbor municipal water supply well.
