• Australia is suing 3M for A$2 billion over PFAS contamination at military bases.
• The legal action aims to recover costs linked to environmental cleanup efforts.
• This is the largest lawsuit ever filed by the Australian government against a corporation.
• 3M claims it ceased sales of PFAS products in Australia 20 years ago.
• PFAS exposure has been linked to serious health issues, heightening public concern.

The Australian government has initiated legal action against US-based manufacturing giant 3M, seeking A$2 billion (approximately US$1.4 billion) in damages related to contamination from firefighting foam that contained PFAS, commonly referred to as "forever chemicals." According to Attorney-General Michelle Rowland, this lawsuit represents "the most significant legal action taken by an Australian government," aimed at addressing both past and future costs associated with environmental remediation at 28 military bases across the country, according to BBC, Reuters, and Channel News Asia.

The Australian government alleges that 3M misrepresented the environmental safety of its firefighting foam and failed to disclose known risks associated with PFAS, which do not biodegrade and have been linked to health issues, including cancer. Rowland emphasized that this legal action is crucial for recovering significant costs related to investigations and management of the contamination, which have already exceeded A$1 billion, according to BBC and Reuters.

In its defense, 3M maintains that it never manufactured PFAS in Australia and stopped selling the foam there approximately 20 years ago. Despite this, the Department of Defence reportedly continued using PFAS-containing products for many years afterward, complicating the contamination issue. The government's legal claim reflects both immediate cleanup costs and ongoing concerns over the health of affected communities, as PFAS exposure has been linked to a host of health problems, according to Reuters and Channel News Asia.

The contamination crisis has prompted the Australian Defence Force to spend A$1.3 billion addressing PFAS-related issues, including the removal of over 200,000 metric tons of contaminated soil and treatment of billions of liters of water. The actions taken by the government illustrate the pervasive impact of PFAS contamination and the growing public health threat, which has led to legal settlements and community efforts to mitigate risks, according to BBC, Reuters, and Channel News Asia.
