![]() ![]() ![]() Now, I don't mean to suggest that it isn't a big deal that "nearly" seven percent of the drinking water sources studied contain PFAS at concentrations greater than those EPA now believes to be safe but that's a lot different than "nearly half". You have to get to the ends of some but not all of the reports to find that EPA's proposed drinking water standard of no more than four parts per trillion for PFOA, the more often detected PFAS, was exceeded in only 6.7 percent of the drinking water sources studied. Everyone from Bloomberg to CNN to the Boston Globe is reporting today on US Geologic Survey research concluding that "nearly half" (45 percent to be precise) of US drinking water sources contain detectable concentrations of the two most common chemicals known collectively as PFAS.
