An Update on Gelman Dioxane Contamination and the EPA Superfund Process

Roger Rayle, a prominent local environmental advocate, citizen scientist, and community organizer will discuss recent developments with the Gelman Dioxane plume that threatens Ann Arbor's water supply. Roger is chair of the Coalition for Action on Remediation of Dioxane (CARD), an organization that has been crucial in responding to the Gelman plume. Roger is widely recognized for compiling, mapping, and visualizing environmental data. He has spent decades creating detailed visual aids, spreadsheets, and interactive maps to help the public, local officials, and regulators track the movement, concentration, and expansion of the 1,4-dioxane plume over time.
