FYI on the tracer Anion bis(trifluoromethane)sulfonimide (TFSI) at higher concentrations it can be hazardous (chemical burns) Was used as a tracer as it is another chemical that 3M made/used/disposed at the location in question. As PFAS is ubiquitous, this provides a way to ID the pollution plume.
Very good news for the City of Hastings! 3M will now need to cover some of the costs to treat Hastings' drinking water. "They will get about $14.5 million from the 3M settlement, but it falls short of the $70 million needed to build three new treatment plants." 1/2 www.mprnews.org/story/2024/1...
The Minnesota Pollution Control Agency announced it's linked PFAS contamination in one of Hastings’ wells to 3M's Cottage Grove facility. City officials say the money will help, but won’t cover the fu...
A little of both. Anion bis(trifluoromethane)sulfonimide (TFSI) at higher concentrations it can be hazardous (chemical burns). Was used as a tracer as it is another chemical that 3M made/used/disposed at the location in question. As PFAS is ubiquitous, this provides a way to ID the pollution plume.
Ah so it’s for an app that tracks which restaurants use industrial seed oil and things like PFAS cookware. I was curious and it did have some places in Seattle on the map. Now I know where to find beef tallow fries at least (so much better). Quite the marketing strategy though!
Posted @withregram • @globalpositivenews Minnesota is set to implement a groundbreaking ban on products containing PFAS, or "forever chemicals," starting in 2025. This ban will affect thousands of items, including carpets, cosmetics, and cookware.
The researchers point out that although air emissions of PFAS are substantially lower now than they were prior to 2019, they are not zero, so some atmospheric deposition of PFAS seems likely to continue to feed into the groundwater.
It could take decades for natural groundwater flow to flush out groundwater PFAS still present from the 'high emission years,' roughly the period between 1980 and 2019," Genereux says.
It could take over 40 years for PFAS to leave groundwater Per- and polyfluoroalkyl chemicals, known commonly as PFAS, could take over 40 years to flush out of contaminated groundwater. www.sciencedaily.com/releases/202...
This was an expected result as most east Twin Cities metro communities have elevated PFAS concentrations in their groundwater. The issue with Hastings is that the MPCA was having difficulty definitively proving that the PFAS were due to waste from 3M. That connection has now been established. 2/2
NYT advice on how to avoid PFAS: Simply stop doing all the day-to-day, unavoidable things everyone normally does, and throw out all your pans, clothes, and furniture. Easy peasy www.nytimes.com/2024/10/07/c...
They’re almost everywhere. And they’re bad. But there are some things you can do to avoid them.
ok, John Lewis says no PFOA (which is one of the PFAs, but then you get PFAs on cast iron pans anyway)
