Australia sues 3M for $1.4B over PFAS contamination
The Australian government filed a Federal Court lawsuit against 3M and 3M Australia seeking more than AU$2 billion (about $1.4 billion) over PFAS contamination at 28 defense sites.[1]
Australia's Defense Department says it has already spent about AU$1.3 billion (roughly $920 million) cleaning contaminated sites, including removing about 220,000 U.S. tons of soil and treating 3.4 billion gallons of water.[1] Attorney-General Michelle Rowland alleges 3M withheld crucial information about the environmental risks tied to its firefighting foam.[1]
3M's fluorinated firefighting foams were used to fight fuel fires as far back as the 1950s.[1] Those per- and polyfluoroalkyl substances, known as PFAS, do not break down easily and can contaminate soil and groundwater.
Minnesota regulators filed a separate PFAS suit against 3M on May 1, 2026, alleging ongoing discharges near its Cottage Grove facility.[1] 3M previously paid $850 million to settle an east-metro Minnesota case in 2018 and agreed in 2024 to pay $10.3 billion over 13 years to address PFAS in U.S. public drinking water systems.[1]
