February 17, 2022 Town Hall Meeting

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) participated in a town hall meeting conducted and hosted by Scio Township in Washtenaw County. Due to concerns about the potential expansion and migration of 1,4-dioxane (dioxane) contamination, related to the Gelman Sciences Inc. Site, Scio Township conducted sampling and analysis of selected residential wells in July and November 2021. The samples were analyzed using Environmental Protection Agency (EPA) Method 522, a test that was developed specifically for dioxane with a detection limit of 0.12 micrograms per liter (ug/L, or parts per billion).

At the town hall meeting Scio Township presented a summary of their sampling activities and results. EGLE presented a summary of the Gelman Site including the status of investigation activities, remediation activities, the EGLE residential well sampling program and the new EGLE interactive web map. Other participants in the town hall meeting included the Michigan Department of Health and Human Services (MDHHS) and the Washtenaw County Health Department (WCHD).

A more detailed presentation of the Scio Township residential well sampling activities can be found on Scio Township's Gelman Sciences Dioxane Contamination page.
