The Australian government has filed a $1.4 billion lawsuit against U.S. manufacturing giant 3M over contamination from firefighting foam at 28 defense bases, marking the country's largest-ever claim for compensation and highlighting the massive fiscal burden taxpayers face from environmental cleanup costs.
The Federal Court suit targets Minnesota-based 3M Company and its Australian subsidiary over contamination with per- and polyfluoroalkyl substances, known as PFAS or "forever chemicals" because they don't break down naturally. The legal action comes after the Australian Defense Department has already spent AU$1.3 billion ($920 million) managing and mitigating the environmental impacts.
Corporate Response and Timeline
3M said it would contest Australia's claim, noting the company "has never manufactured PFAS in Australia and ceased sales of the products at issue in Australia around two decades ago." The company pointed out that "the (Australian) Department of Defense continued to use PFAS-containing firefighting foams for nearly two decades longer" after 3M stopped selling the products.
PFAS has been used since the 1950s in household and industrial products that resist heat, stains, grease and water. The firefighting foam containing PFAS was effective against fuel fires, making it a standard tool at military installations.
Scope of Contamination
The contamination issue became public in 2018 when the Australian Defense Department warned residents near its Richmond Air Base outside Sydney to reduce their consumption of locally produced fish and eggs after PFAS was found in nearby groundwater. Assistant Defense Minister Peter Khalil said his department had removed 200,000 metric tons (220,000 U.S. tons) of contaminated earth from bases and treated 13 billion liters (3.4 billion gallons) of contaminated water.
Government's Legal Strategy
Attorney-General Michelle Rowland accused 3M 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 reporters.
Khalil emphasized the government's willingness to pursue litigation against major corporations. "We are prepared to take on powerful corporations when Australians and Australian communities have been impacted," Khalil said.
The lawsuit represents an attempt to shift cleanup costs from taxpayers to the manufacturer, though 3M's defense suggests a potentially lengthy legal battle over responsibility for contamination from products the Defense Department continued using long after the company ceased Australian sales.
Why This Matters:
This lawsuit represents a critical test of whether taxpayers or manufacturers bear the financial burden of environmental cleanup when government agencies continued using products after safety concerns emerged. With AU$1.3 billion already spent and more than AU$2 billion sought in damages, the case highlights the massive fiscal exposure governments face from legacy contamination issues. The outcome will establish important precedents for corporate liability when government entities make independent decisions to continue using products after manufacturers exit the market. For taxpayers, the case raises questions about government procurement decisions and whether defense officials adequately assessed risks before decades of continued use. The litigation also tests the limits of holding manufacturers accountable for products used long after sales ceased, a distinction that could affect similar environmental claims globally and ultimately determine who pays for costly remediation efforts.
