Gelman Sciences (now Pall Corp., a division of Danaher
Corp.) polluted groundwater in parts of Washtenaw County, including parts of
the City as well as Ann Arbor and Scio Townships, when it improperly disposed
of industrial solvents containing 1,4-dioxane between 1966 and 1986. That
pollution has since spread through the aquifer. The City is engaged with
neighboring communities and the state to, among other things, push Gelman to
delineate, contain and clean up its pollution. To that end, the City has,
for example, intervened in litigation in Washtenaw County Circuit Court brought
by the State against Gelman.
The MDEQ encourages property owners with concerns about potential dioxane contamination to contact Dan Hamel, the MDEQ's project manager for the Gelman plume site, by calling 517.745.6595 or emailing email@example.com.
