Researchers find high levels of PFAS chemicals in rainwater in United States
News
18 Dec 2019 | The Weather Channel
Most of the samples had PFAS concentrations of less than 1 ng/l, or 1 ppt, but several were about 4 ng/l. The highest total concentration was nearly 5.5 ng/l in a sample from Massachusetts. For drinking water, some states have proposed setting the level at which some type of official action is required at 2 nanograms per liter.

10 toxic ‘forever chemicals’ found in Louisville, KY, tap water
News
22 Oct 2019 | EWG News
The highest level of any single PFAS detected in the EWG sample collected in Louisville was 22 ppt of a compound known as GenX. It is a replacement chemical for PFOA, which was used to make Teflon before U.S. manufacturers phased it out of production under pressure from the EPA. The EPA’s research has found that GenX is nearly as toxic as the PFOA it replaced, and DuPont, its original manufacturer, has provided test results to the EPA showing that GenX caused cancer in lab animals.

New science on PFAS chemicals should mobilize our senators
News
19 Sep 2019 | The Fayetteville Observer
A peer-reviewed study, published this month in the prestigious Chemical Engineeri Journal, found short-chain PFAS chemicals, like GenX, are more widely detected, more persistent, and more mobile than long-chain PFAS chemicals they were designed to replace--such as PFOA and PFOS... This is profound news considering PFAS chemical makers, like Chemours, continue to claim GenX and other short-chain PFAS are safer replacements.
