1-4 Dioxane

Jorge Avellan / 89.1 WEMU

For decades, the Michigan Department of Environmental Quality has been working with Gelman Sciences to clean-up the 1,4 Dioxane chemical the company released in certain parts of Ann Arbor.  To this day, the DEQ continues to say the levels are below their precautionary standards and are not harmful. To give voice to concerned residents, city, county and state officials put together Thursday night's town hall forum.

Ann Arbor’s dioxane plume is rather unusual, in that it emanates from just one source. That source is the old Gelman Sciences facility on Wagner Road in Scio Township. Other area's of dioxane contamination around the country, such as  the KL Avenue Landfill in Kalamazoo, have many “Responsible Parties” contributing to the contamination problem. Even with a single source, assigning responsibility for clean-up remains complicated in Ann Arbor.  In this installment of "The Green Room"  we try to untangle the confusing web of who is who when it comes to liability.

It’s been over three decades since Ann Arbor’s groundwater contamination was discovered, and throughout this time, citizen science and community advocacy have had a crucial role.  In this edition  of 'The Green Room,' Barbara Lucas looks at the uphill battle from its earliest steps.

  The National Priorities List is the list of hazardous waste sites in the United States eligible for long-term remedial action financed under the federal Superfund program.  Currently there are 1,171 sites on the NPL, either being cleaned up or waiting for their turn.  Should Ann Arbor’s 1,4-dioxane contamination be “listed” too?  Weighing benefits against potential stigma costs is the subject of this week’s Green Room segment in our ongoing series.

The University of Michigan’s research in human and environmental health is of global import.  Should the university “think local” as well?  In this segment of WEMU’s “The Green Room,” Barbara Lucas looks at the University of Michigan and the Ann Arbor area’s 1,4-dioxane contamination.

Drinking water samples from more than three dozen homes in Ann Arbor and Scio Township will be tested for 1,4 dioxane. 


City of Ann Arbor

The city of Ann Arbor has released its annual drinking water quality report.  Brian Steglitz is the manager of water treatment services for the city.  He says they continue to meet or exceed all state and federal regulatory requirements.  There is no issue with lead in Ann Arbor's drinking water like there is in Flint.

A town hall meeting will be held this evening from 6PM to 8PM in Ann Arbor to discuss the latest dioxane plume situation in the area.

Since 1995, 4,000 prohibition zones have been put in place in Michigan to “manage risk,” i.e. prevent people from coming into contact with contaminated soil or water.  In this installment of WEMU’s “The Green Room,” Barbara Lucas looks at how the balance between cleaning up pollution versus managing the risk is playing out when it comes to the Ann Arbor area's 1.4 dioxane plume.

There is a long road ahead to adequately address an expanding 1,4 dioxane plume in the Ann Arbor area. The plume has contaminated wells in Scio township and Ann Arbor and is slowly moving towards the city's municipal water supply at Barton Pond. In this month's '1st Friday Focus on the Environment',  Liza Wozniak talks with Washtenaw County Commissioner Yousef Rabhi about the next steps in the journey.
