In November 2018, a complaint was filed against 3M and Georgia-Pacific. The complaint claimed PFAS chemicals had migrated into the Parchment, Michigan drinking water supply from a former paper mill and its associated facilities. The complaint sought monetary damages for diminished property value, property damage, interference with use and enjoyment of property, stigma damages, and medical monitoring from exposure to PFAS.
A settlement of $11.9 million was reached in April 2021. The settlement class included anyone who owned, leased, rented, or resided in homes or residential properties serviced by the Parchment water system as of July 26, 2018, but has not brought individual actions for illness or personal injury based on PFAS exposure.
