Australia sues US giant 3M for $2bn over 'forever chemicals' in firefighting foam

The Australian government has filed a lawsuit seeking AU$2bn in damages from US manufacturing giant 3M over contamination from toxic 'forever chemicals' in firefighting foam used at defense sites^[1][2].

Attorney-General Michelle Rowland announced the legal action, calling it the largest claim ever brought by the government^[1]. The suit alleges contamination at 28 locations across the country^[1][2]. It accuses 3M of withholding and misrepresenting details about the foam and its environmental impact, despite knowing the risks^[1][2]. The government states it has already spent over AU$1bn to investigate and remediate the PFAS contamination^[1].

PFAS, or per- and poly-fluoroalkyl substances, are known for water-resistant and non-stick properties and do not break down under normal environmental conditions^[2]. In 2022, 3M said it would stop making and using PFAS^[2]. However, the company has denied responsibility for the Australian contamination, stating it never manufactured PFAS in the country and stopped selling the foam there 20 years ago^[1]. A 3M spokesperson said the company would defend itself against the claims^[1]. The government's case alleges 3M gave assurances about disposal and environmental safety that were inconsistent with its internal knowledge^[1].
