Scientists cut the tolerable intake of PFAs by 99.9%

A White House aide reportedly described the document as a “public relations nightmare,” as it suggests “safe” levels of PFASs are about 10 times lower than the current EPA drinking water guidelines. One part per trillion is about one drop of water in an Olympic swimming pool; by the standards in the ATSDR report, a PFASs exposure greater than approximately two thousandth (0.002) of a drop in the average yearly water intake of an American adult could be considered potentially unsafe. Trying to visualize 0.002 of a drop illustrates what sets apart PFASs from the slew of other chemicals in our environment: they are harmful at really low levels, yet millions of people are subjected to them via drinking water and other sources every day.
