89.1 WEMU

It's been over a year since state officials in Michigan acknowledged Flint was in the midst of a water crisis and many of the city's children were suffering with high lead levels in their blood. Dr. Mona Hannah-Attisha brought the lead concerns to the fore and has remained an advocate for the children and safe water in Flint and around the state. She discusses where we've been and where we're going with David Fair and Michigan League of Conservation Voters executive director Lisa Wozniak .

For two decades the State of Michigan’s “containment” policy has allowed polluters to leave contamination in place rather than clean it up.  4,000 such “prohibition zones” exist in the state.  In our ongoing look in the Ann Arbor area's 1,4 dioxane plume, we look at the ramifications of that kind of policy.

As concern rises and detection methods improve, 1,4-Dioxane is being discovered in water sources across the country. Central to formulating remediation plans is determination of the safe level of exposure to this probable human carcinogen. What constitutes a true hazard as opposed to an “acceptable risk?”  Barbara Lucas goes in search of the answer in this 24th installment in our series on the Ann Arbor area’s 1.4 Dioxane Plume in “The Green Room.”

At a September work session, Ann Arbor City Council members asked city staff if the current water treatment plant could accommodate equipment to remove 1,4 dioxane,  just in case it becomes necessary in the future.  In this installment of 89.1 WEMU’s “The Green Room,” we look at what such a water treatment process looks like in action.

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.

The cast of players involved with Ann Arbor’s dioxane problem has changed many times over in the thirty years since the contamination was first discovered.  Some say that’s part of the problem:  it’s hard to stay motivated to tackle problems that go on seemingly indefinitely. Luckily, there are a few people in the community who have stuck with it, keeping the issue in the public forum.  In this segment of WEMU’s “The Green Room,” we talk with one of them.

While the federal advisory level is 3.5 parts per billion, the amount of dioxane the State of Michigan allows in drinking water is 85 ppb, one of the highest standards in the country.  High levels mean less extensive remediation plans, a boon to industries responsible for the cleanups.  But, could the resulting water pollution negatively impact other businesses, and the local economy in general?  In this installment of  WEMU’s “The Green Room,” Barbara Lucas looks at various perspectives on this question.

In our previous 18-installments on the Ann Arbor area’s 1, 4 dioxane plume, we’ve heard from citizens, scientists, and government officials; both locally and from other dioxane sites around the country. Meanwhile, requests for interviews with the “Responsible Party”—Gelman Sciences, Pall Corporation or Danaher, are all met with silence.  In this episode of “The Green Room,” we learn, that wasn’t always the case.

Good communication between all parties involved is central to productive conflict resolution.  Some say it needs improving when it comes to dealing with Ann Arbor’s dioxane-contaminated groundwater. In this segment of our ongoing series, Barbara Lucas looks at the question:  “What part does communication play in how we move forward?”

A plume of 1,4-dioxane has been spreading under Ann Arbor since the 1980s.  During this time, numerous homes on private wells have had dioxane in their drinking water before being hooked up to city water.  Is that the only source of dioxane to consider when weighing body burdens?  In the 15th of our series on 1,4-dioxane, Barbara Lucas looks at other ways people can be exposed to this chemical of emerging concern.

Flint’s lead crisis has led to an increased concern about the dioxane plume in Ann Arbor’s groundwater.  In this 14th segment of WEMU’s “The Green Room” series on the Ann Arbor contamination plume, Barbara Lucas considers the dioxane content of bottled and tap water.

On June 14th a resolution was passed by the Scio Township Board of Trustees aimed at addressing the 1, 4 dioxane plume that has spread from the old Gelman Sciences facility on Wagner Road. It seeks Superfund designation from the United States Environmental Protection Agency. The Washtenaw County Board of Commissioners and City of Ann Arbor are considering similar resolutions.  A meeting is being arranged between all government entities involved, at the local, state and federal levels. Until that meeting takes place, there are many unknowns and much speculation.  In this week’s 'The Green Room' segment, we look at one perspective.

In the United States, approximately 10 million pounds of 1,4-dioxane are produced each year.  It is being detected in groundwater at dozens of sites across the country.  Once thought to be relatively benign, new science says otherwise.  Costs to clean it up are high, and communities are grappling with how to deal with it.  In this installment of  “The Green Room,” WEMU  explores the experiences of two cities:  Ann Arbor, Michigan, and Tucson, Arizona.

Remediation of an expanding 1, 4 dioxane plume continues, but the chemical continues to slowly spread towards the Huron river. That's the topic in this month's edition of '1st Friday Focus on the Environment.'  Lisa Wozniak is Executive Director of the Michigan League of Conservation Voters and host of the monthly feature. Her guest is 12th District Congresswoman Debbie Dingell.
