The Australian government is suing chemicals manufacturer 3M over PFAS contamination at 28 defence bases across the country [1].
This legal action represents the largest claim in Australian history, signaling a significant shift in how the government addresses long-term environmental liability and public health risks associated with industrial chemicals.
The lawsuit, filed in 2024 [2], alleges that per- and polyfluoroalkyl substances, known as PFAS or "forever chemicals," contaminated sites through the use of firefighting foam. These chemicals are characterized by their inability to break down naturally in the environment, leading to persistent pollution in soil and water.
The legal claim seeks more than 2 billion AUD [2], which is approximately 1.4 billion USD [2]. The government said that the contamination has caused extensive environmental damage and posed health risks to those exposed to the sites.
Contamination is reported across every Australian state and territory [1]. While the impact is nationwide, the majority of the affected sites are located in New South Wales, Queensland, and Western Australia [1].
PFAS were widely used in aqueous film-forming foams (AFFF) for decades due to their effectiveness in extinguishing flammable liquid fires. However, the resulting runoff has led to the contamination of groundwater and surface water near military installations and airports globally.
The Australian government is pursuing the manufacturer to recover costs associated with the remediation of these 28 sites [1]. The scale of the litigation reflects the complexity of cleaning up sites where chemicals persist indefinitely, a challenge that has led to similar legal battles in the U.S. and other jurisdictions.
“The Australian government is seeking more than 2 billion AUD in the nation's largest legal claim.”
This litigation underscores a growing global trend of holding chemical manufacturers accountable for the lifecycle of persistent pollutants. By targeting 3M for the cleanup of military sites, Australia is attempting to shift the financial burden of environmental remediation from taxpayers to the producer of the chemicals. The outcome of this case could set a legal precedent for how other nations manage PFAS contamination and may influence future industrial regulations regarding the use of synthetic chemicals in government procurement.
