Dioxane plume

There’s tons of documentation on the plume’s legal, technical and local history, but finding answers to big-picture questions can be difficult. Here's what I've learned after 18 months of research.

Locals have been pushing for more aggressive solutions to the Gelman plume, but the company isn't required to fully clean it up. EPA intervention could change that — if it survives Trump 2.0.

Rita Loch-Caruso and the Yale Superfund Research Center want to use Ann Arbor’s case study to learn more about what they call “another forever chemical.” There’s a lot to learn and a surprising amount that isn’t known.

An update on the toxic chemical Gelman plume nearing Ann Arbor's drinking water source, Detroit and other Michigan regions are sinking, a local play examines the relationship between technology consumers, and technology creators and preview of the 2025 Mackinac Policy Conference.

Marianne Martin has lived in the same home for over 50 years, despite groundwater contamination that rendered her drinking water well unusable. She sued the company responsible — and lost. Now she’s worried the same contamination could threaten Ann Arbor's drinking water.

The EPA moves a step closer to cleaning up a toxic plume spreading underneath Ann Arbor, Detroit Youth Poetry Convention taking place this weekend, and bring traditional Sudanese drink Hilo Mur to Michigan

Last month, the Gelman plume became a candidate for the Environmental Protection Agency’s Superfund program. What does this mean for Ann Arbor and Scio Townships?

Local officials and advocates have asked that the site be included on the National Priorities List to bring more resources to bear on site monitoring and remediation.

The U.S. EPA says a preliminary assessment of the 1,4 dioxane contamination spreading in the city of Ann Arbor's groundwater shows the site has a "good chance of being listed under the federal government's Superfund program.

A newly published study suggests as the polluted groundwater moves east, it gets closer to the surface. It suggests regulators should monitor for vapors in basements in those areas.
