We&#8217;re talking significant amounts. They&#8217;re super water-soluble, move around easily, and conventional treatments like activated carbon barely touch them. Plus, they&#8217;re mostly unregulated and stick around in the environment forever.

In Europe, the focus has shifted from regulating individual PFAS to looking at the whole group. But here's the thing: PFAS are incredibly diverse, and we still don't know much about them beyond the older, well-studied long-chain and short-chain PFCAs and PFSAs. We've got some data here, both quantitative and semi-quantitative, for 43 of these short-chain and ultra-short-chain PFAS. This means compounds with two or fewer perfluorocarbon atoms for PFCAs, and three or fewer for PFSAs and other PFAS. We pulled 46 water samples from 13 different German drinking water sources. Some of the PFAS we looked at are pretty new, like hexafluoroisopropanol, bis(trifluoromethylsulfonyl)imide, and tris(pentafluoroethyl)trifluorophosphate.<\/p>\n<p class=\"articleBody_abstractTextWhat did we find? Ultra-short-chain PFAS like trifluoroacetate, perfluoropropanoate, and trifluoromethanesulfonate were everywhere. And they were present in the highest concentrations, making up 98% of all the target PFAS we found. It turns out, common \"PFAS total\" measurements, like adsorbable organic fluorine (AOF) and the total oxidizable precursor (TOP) assay, don't tell the whole story. They miss these very common ultra-short-chain PFAS. These tiny PFAS are a huge problem for producing clean drinking water, and it's clear we need preventative measures to manage them.<\/p>\n<\/div>\n<p>The post Ultra-Short-Chain PFASs in the Sources of
