Background ​​​

Ann Arbor City Council recently took additional action to support the cleanup efforts of contaminated groundwater in areas of the city. On November 14, 2016, the City Attorney's Office filed a motion in Washtenaw County Circuit Court to intervene in the Gelman dioxane plume case.

Groundwater in parts of Washtenaw County, including some areas in the city of Ann Arbor and Ann Arbor and Scio townships, is polluted with the industrial solvent 1,4-dioxane due to Gelman Sciences', now Pall Life Sciences (PLS), improper disposal of wastewater containing the chemical between 1966 and 1986. As a result of their actions, the chemical seeped through soil and rock layers into the groundwater and has since spread.

It is important to note, however, that Ann Arbor's drinking water is safe, as no 1,4-Dioxane has ever been detected to date in the municipal drinking water supply. 

On Oct. 24, Ann Arbor City Council approved a resolution directing the city administrator to explore options for more expeditious and effective cleanup efforts, including possible collaboration with Washtenaw County, Scio Township, Ann Arbor Township and other affected jurisdictions. The administrator is being asked to seek assistance from the community's Congressional delegation to explore whether the Michigan Department of Environmental Quality is fulfilling its delegated authority under the Clean Water Act and the Safe Drinking Water Act, and to provide Council with a status of these efforts on a monthly basis.

A special session of Ann Arbor City Council regarding a resolution concerning Pall Gelman 1,4-dioxane litigation was held Nov. 1, 2016. Ann Arbor residents can view this meeting on CTN video on demand. 

The MDEQ is encouraging property owners with concerns about potential dioxane contamination to contact Dan Hamel, the MDEQ's project manager for the Gelman plume site, at 517.780.7832 or hameld@michigan.gov.
