World 3M sued for record $1.4 billion by Australia over "forever chemicals" at defense bases May 28, 2026 / 6:42 AM EDT / CBS/AP Add CBS News on Google Melbourne, Australia — Australia is suing U.S. conglomerate 3M for more than 2 billion Australian dollars ($1.4 billion) over so-called "forever chemical" contamination from firefighting foam at defense bases, the government said on Thursday.The government's largest-ever claim for compensation relates to contamination with per- and polyfluoroaklyl substances, known as PFAS, at 28 bases.

The Australian Defense Department warned residents near its Richmond Air Base outside Sydney in 2018 to reduce their consumption of locally produced fish and eggs, after PFAS were found in nearby groundwater. Attorney-General Michelle Rowland accused 3M on Thursday of withholding information about environmental risks the foam posed."The Commonwealth (of Australia) is seeking more than AU$2 billion ($1.4 billion) in damages to recover significant past and future expenses incurred in investigating and managing contamination resulting from the historic storage and use of this foam," Rowland told repo...
