Manufacturer 3M warned over chemicals at quarry
PFAS soil, sediment, groundwater and surface water have been found across a 100-hectare area of the inactive Brogans Creek lime quarry northwest of the Blue Mountains, the NSW Environment Protection Authority says.
The authority has for the first time issued a clean-up notice and took regulatory action against 3M and its local Australian arm.
"This is a significant moment for the EPA and one that represents an important milestone in our efforts to address legacy environmental harm," Operations Director David Gathercole said.
"Though this is only the first step ... 3M has so far been co-operative voluntarily offering to conduct investigation to better understand the extent and legacy of PFAS contamination."
PFAS, or per- and polyfluoroalkyl substances, are a group of 15,000 highly toxic, synthetic chemicals used for their resistance to heat, stains and grease.
They have been dubbed "forever chemicals" because they break down extremely slowly.
Emerging evidence has linked some PFAS substances to cancer, leading to tighter regulation of the substances, particularly in drinking water.
The quarry, in the state's central west, was historically used by 3M to test PFAS-containing firefighting foam.
The authority said while "the scale of the onsite contamination is significant", there is limited human exposure because of the remoteness of the site.
However, it found some of the chemicals eight kilometres downstream in the Capertee River within a national park.
They were considered to be above the national drinking guidelines.
A sign has been erected warning park users to not drink river water. But recreational use including swimming remains safe, the authority said.
Under the clean-up notice, 3M Australia has 60 days to submit a detailed plan to manage PFAS pollution.
The company has been contacted for a comment.
The chemical conglomerate behind Post-it notes and Scotch-Brite has been handed a yellow card over "significant contamination" from historic toxic chemicals found in a quarry it leased.

‘We haven't looked back': How these eight schools are turning around results
Two Central Coast schools – The Entrance Public and Budgewoi Public – were highlighted in a new report by The Grattan Institute, The Maths Guarantee, on how to boost maths performance in primary schools. Stitt credits teaching consistency and 'door-to-floor' class routines for the dramatic turnaround in behaviour. The school recorded 80 suspensions in 2020, last year that fell to 20. Just three suspensions have been issued in the first two terms of this year, he says. He recalls starting at the school in 2019, when 'classrooms would be trashed, we had violence. I was constantly at rooms getting turned over. We would have to evacuate the classrooms,' he says. Teachers became afraid to teach, he says. 'We had to draw a line.' 'Open plan learning didn't really work here. That free-range approach, the students didn't cope well. Kids were disengaged, we had kids facing all different ways. It can add to cognitive load too, so we did away with that and kids can focus on learning.' The change in teaching approach meant lessons became fast-paced and students were engaged. Teachers check for students' understanding as the lesson progresses, data is monitored carefully. Vocabulary classes were introduced to help students learn up to 400 'tier two' words a year. This year, for the first time, the school's year 3 reading, spelling and numeracy NAPLAN results are above the Australian average. The school is in the top 10 per cent of public schools for value-add data, the contribution a school makes to student learning. Five years ago, about 60 per cent of year 1 students at the school needed extra support with phonics, or identifying letter-sound combinations. Last year, it was 16 per cent. The eight Central Coast schools are also part of a grassroots group known as the Effective and Systematic Teaching Network (EAST) which writes lessons plans schools can use with the kindergarten to year 6 maths curriculum. Sam Higgins, a year 4 teacher at The Entrance who helped write the EAST maths resources, says providing lesson plans is especially useful for new teachers. 'When I started teaching I felt like I was really struggling. You're just left to your own devices, which can lead to a lead to a haphazard approach to teaching. Having shared resources gives you something to lean on,' Higgins said. But Stitt said while there is a high level of structure to the school day, 'there is a lot of room for individualism, warmth, and for the teachers to put their twist on things.' Jesmond Zammit, principal at Gorokan Public, said having a network of schools to share knowledge has helped improve student outcomes. 'We were all doing our own things within each individual school. Now we have a collective where the primary pedagogy is explicit teaching, and we have a laser focus on it,' Zammit said. 'We work together, we visit each other's schools.' At The Entrance and Gorokan Public, about 60 per cent of students come from the lowest socio-educational quartile. 'Aboriginal and Torres Strait Islander students make up 25 per cent of our 610 students. This year their year 5 NAPLAN reading results were off the charts, and well above statistically similar schools,' he said. 'It's been a real game changer for our students in terms of life opportunities. And if they go to another school in this area, then the learning is consistent.' Stitt said one of the major changes is that parents have confidence in the school. 'We get about 60 or 65 per cent at parent teacher interviews. Our aim over the next year is to increase that, really get more parent engagement because we know what a difference that can make.'

I've travelled the world, and these are the 11 greatest breakfasts
I don't know about you, but I grew up eating cereal. Breakfast in many Australian homes and even restaurants can be a predictable affair, a bland offering of stuff with milk poured on it, or toast with things spread across it. Only when I started travelling the world did I discover a whole new approach to starting the day, one that could be savoury or sweet, that could slap you awake with bold flavour or warm you gently with subtlety and finesse. Breakfast doesn't have to come in a box with a cartoon character on the front. It can be a bowl of nourishing noodle soup, a plate of fiery salsa, a spread of steamed and fried delicacies. After many years traversing the globe and eating what the locals eat, these are my absolute favourite ways to kick off a day. Nasi Lemak, Malaysia The basics of nasi lemak would be good enough: rice cooked in coconut milk with pandan leaf, rich and decadent; dried baby anchovies, peanuts, cucumber, a boiled egg and spicy, pungent sambal to bring it together. Heaven. But then you get to add an accompanying dish, something like Malay-style chicken curry, or beef rendang, or a fried or grilled chicken leg, or even a fish curry, and you're in absolute nirvana. Chuck in a 'kopi C' – Malaysian coffee with condensed milk and sugar – and you're set for the day. Full English/Irish/Scottish I couldn't choose just one of these, so I've gone with three, given they're variations on a theme: a massive fry-up to start the day, a heart-warming, artery-clogging mass of classic British and Irish breakfast foods slapped together on a plate. All include eggs, usually fried, and bacon. A full English then has pork sausages, black pudding, maybe mushrooms or tomatoes, and fried bread. A full Scottish has a Lorne sausage, haggis and potato scones. A full Irish has both black pudding and white pudding and soda bread. All are killer breakfasts (in every way).
