Australia's federal government has accused US manufacturing giant 3M of concealing for over five decades the health and environmental risks tied to its firefighting foams, according to newly filed court documents. The allegations are part of a A$2 billion lawsuit against the company.

Lawyers for the Commonwealth argue that 3M was aware, as far back as the 1960s, that ingredients in its products—including those linked to per- and polyfluoroalkyl substances (PFAS), often termed 'forever chemicals'—posed serious threats. These include toxicity to humans and wildlife, as well as lasting contamination of natural resources.

Court submissions detail that the products were sold to Australia even though internal company records allegedly warned they could persist in soil and water, accumulate in living organisms, and contribute to health issues such as impaired kidney function, immune system disruption, fertility and developmental problems, and low birth weights.

The lawsuit is one of the largest environmental

The lawsuit is one of the largest environmental damages claims brought by the Australian government, reflecting growing global scrutiny over the long-term impact of PFAS. The government is seeking compensation for the cost of cleaning up contaminated sites and addressing public health consequences.

3M has previously stated that it adheres to safety standards and that it has been working to phase out certain chemicals. However, the Australian government contends that the company's knowledge and conduct warrant legal accountability. The case is expected to unfold over several years in court.
