A state regulator has issued a clean-up notice to 3M Australia after discovering PFAS contamination at a disused quarry once used for firefighting foam testing.
Xanthe Gregory reports for ABC News.
In short:
- The New South Wales Environment Protection Authority (NSW EPA) ordered 3M Australia to address PFAS contamination at Brogans Creek Quarry, where the company tested firefighting foams between 1980 and 2000.
- Investigations found PFAS in soil, water, and groundwater, including levels above safe drinking water guidelines in a nearby river within a national park.
- 3M has 60 days to submit a site management plan or face a fine of up to $2 million; the company has agreed to cooperate with the cleanup.

"This is a significant moment for the EPA and one that represents an important milestone in our efforts to address legacy environmental harm."

Why this matters:
In Australia and globally, firefighting foams have become a major source of contamination, especially around defense and industrial sites. PFAS have been detected in water supplies and even human blood, with one study showing traces in 85% of the Australian population. The chemicals travel through soil and waterways, making their way into ecosystems and food chains. Even though Australia has largely phased out certain PFAS foams, legacy contamination remains a major challenge. The 3M case marks a rare instance of a powerful multinational being held accountable, signaling a shift toward more aggressive regulation in the face of persistent environmental health risks.
