EPA Proposes to Add Gelman Sciences to Superfund National Priorities List

Public comment period is March 7 - May 6

Archived News Release: March 6, 2024 - ​On March 5, U.S. Environmental Protection Agency proposed to add Gelman Sciences Inc., which spans portions of the city of Ann Arbor and Scio Township in Washtenaw County, Michigan, to the Superfund National Priorities List. The NPL is a list of sites throughout the United States and its territories where historical releases of hazardous substances, pollutants or contaminants pose significant threats to human health and the environment. A 60-day public comment period begins March 7.  

“Updating the National Priorities List is a critical component of EPA's comprehensive approach to protecting human health and the environment from contamination, including in communities overburdened by disproportionate environmental impacts,” said EPA Administrator Michael S. Regan. “Cleaning up contaminated land and groundwater and returning them for productive use to communities, especially those which have borne the brunt of legacy pollution, is a win for public health and local economies.”   

“We’re proposing the Gelman site for the Superfund list to ensure that more federal resources are focused on tackling long-standing groundwater contamination in Washtenaw County,” said EPA Region 5 Administrator Debra Shore. “EPA’s robust community involvement program at Superfund sites would also enable us to directly address the concerns of residents and those impacted by the contamination from the facility over many decades.”    

“Including the Gelman Plume on the National Priorities List is critical to bringing federal priority and resources to help finally end this decades-long nightmare for the residents of Ann Arbor, Scio Township, and the surrounding communities. Too often our communities have been pitted against each other, but we know that we accomplish more when we work together,” said Rep. Debbie Dingell. "We have worked hard to bring everyone together to get this done, and I will continue to work closely with the EPA, and with our state and local lawmakers to see this through once and for all.”  

The former Gelman Sciences site manufactured medical filters and related products for pharmaceutical, microelectronics, and pollution testing industries. In 1966, Gelman began using 1,4-dioxane as a solvent for filters and cleaning process lines. Gelman’s operations caused the release of hazardous substances from years of handling 1,4-dioxane on its facility grounds. On-site manufacturing operations ceased in 2013. Nearly 8,000 people living within the 4-mile radius may be affected by the contamination.
