The EPA says it's okay to have up to 2000 tiny bits of PFBS in a trillion drops of drinking water, but only 10 bits of GenX — showing that safety levels for these chemicals vary a lot.

Similar Assertions

The EPA just made its safety limits for two harmful chemicals in drinking water way stricter — now saying even tiny amounts of PFOA and PFOS can be risky, much lower than before and compared to other countries.

Different health agencies can't agree on how much of certain 'forever chemicals' like PFOA are safe to be exposed to — their safety limits vary by as much as 1,000 times, so experts say they need to get on the same page.

The EPA just made the safe limit for two harmful chemicals in drinking water way stricter—dropping from 70 to just 4 tiny parts per trillion—but some scientists are saying that big drop isn't really backed by solid science.
