The 1,4-dioxane plume extending from the Pall site, in Ann Arbor

Washtenaw County Circuit Court Judge Donald Shelton ordered a change in cleanup requirements  for Pall Life Sciences, successor to Gelman Sciences, to address groundwater contaminated with 1,4-dioxane.

The Gelman Sciences property, located on Wagner Road just south of Jackson Road in Scio Township, manufactured medical filters. Dioxane used at the plant from 1966 to 1986 was disposed of by various methods, resulting in widespread groundwater contamination in portions of the city of Ann Arbor, Scio and Ann Arbor Townships.

The first contaminated private water supply well was discovered in 1985. Since then, more than 120 contaminated private wells have been replaced with municipal water. Pall Life Sciences acquired the property from its original owner in 1997 and undertook responsibility for continuing the cleanup efforts.

Pall and the MDNRE have been in dispute about how best to clean up the site.  Today’s action resolves those disputes.

The MDNRE will host a March 30 public meeting in Ann Arbor to discuss the cleanup effort and answer questions about the court order. The meeting begins at 7 p.m. at the Abbot Elementary School, 2670 Sequoia Parkway.
