In June 2023, multinational industrial conglomerate 3M reached a historic settlement with public water suppliers over the presence of polyfluoroalkyl and perfluoroalkyl substances (PFAS) in drinking water. The settlement concluded multiple class action suits against the company. Under the settlement, 3M will pay $10.3 billion to plaintiffs over a 13-year period.

Marsh McLennan Agency’s Lydia Zaharia, Drew Flynn and Susanne Deegan discuss the impact on businesses of regulatory changes regarding PFAS, and offer a framework to minimise risk for affected firms.
