CNN — Almost half of the tap water in the US is contaminated with chemicals known as “forever chemicals,” according to a new study from the US Geological Survey.

The number of people drinking contaminated water may be even higher than what the study found, however, because the researchers weren’t able to test for all of these per- and polyfluorinated alkyl substances, or PFAS, chemicals that are considered dangerous to human health. There are more than 12,000 types of PFAS, according to the National Institutes of Health, but this study looked at only 32 of the compounds.

The scientists collected water samples directly from taps at 716 locations – 269 from private wells and 447 from public sources – between 2016 and 2021. Based on their findings, they estimate that at least one PFAS chemical would be detected in 45% of US drinking water samples.

    Wouldn’t that mean receiving a blood transfusion would increase the amount of forever chemicals in your body?

    I wonder if dialysis filters these out?

      maybe, if the incoming blood has PFAS in it then yeah because you can’t process it out.

      No idea ablut dialysis, i guess it would depend on the molecule size and filter size
