Michigan PFAS Contamination Suit against 3M, Wolverine Moves Forward

Plaintiffs, a group of Michigan residents, alleged that 3M and Wolverine’s PFAS-containing Scotchgard products polluted their drinking water and lowered property values. The companies moved to dismiss the complaint, which alleged claims for negligence, private nuisance, and public nuisance and sought medical monitoring, monetary damages, and remediation funding. The court ruled that the plaintiffs did not allege any actual physical injury capable of sustaining a negligence claim, as fear of a future injury does not suffice. The court, however, allowed the remaining claims to proceed.

Federal Government Challenges New Mexico’s Definition of PFAS as Hazard Waste

The United States filed for summary judgment in its suit over a hazardous waste remediation permit issued by the New Mexico Environment Department (NMED), arguing that the substances covered by the permit exceeded the state’s authority. The United States contends that NMED acted arbitrarily and capriciously by including PFOS and PFOA among the substances considered “hazardous waste” because neither of these chemicals are identified as such under the Hazardous Waste Act or EPA’s regulations.

New York PFAS Contamination Case Survives Motion to Dismiss

The District Court for the Northern District of New York denied a motion to dismiss a group of New York residents’ personal injury claims against 3M, DuPont, Honeywell, and Saint-Goban Performance Plastics. The residents alleged that the chemical companies contaminated their drinking water with PFAS. However, some plaintiffs failed to produce authorizations for medical and employment histories and water or blood testing results. After the chemical companies requested dismissal, plaintiffs responded with the requested information, and unresponsive plaintiffs were voluntarily dismissed. The court found that dismissing the claims would be “too severe a sanction.”

City of Dayton, Ohio Seeks $310 Million from U.S. Air Force for Alleged PFAS Contamination

The City of Dayton, Ohio filed a complaint under the Federal Tort Claims Act against the United States for alleged PFAS contamination of the City’s drinking water supply originating from a nearby Air Force base. The Wright-Patterson Air Force Base had been using firefighting foam that contained PFAS since 1970. Although the Ohio EPA ordered the Base to clean up the chemicals in 2016, plaintiffs allege that the Base never proposed or implemented any remediation actions.  The complaint alleges claims for public nuisance and continued trespass and seeks reimbursement for past, present, and future cleanup costs.
