Summary

A US Geological Survey study estimates PFAS chemicals may contaminate drinking water for up to 70% of the 140 million Americans using aquifers, affecting around 95 million people.

Some groundwater readings were up to 37,000 times the EPA’s new limits. Private wells and small public wells, which serve 13% of the population, lack strict EPA PFAS regulations, making them especially vulnerable.

Contamination is most severe near military bases, airports, and industrial sites, with high exposure in Michigan, Florida, and California.

The USGS also produced an interactive map that shows where there may be trouble.

    Agreed, they are more expensive. Are they the most expensive? No. Do you have a better short term alternative? One option would be to use distillation. It would be lovely to remove PFAS entirely from the planet, but that isn’t happening in the short term, unless you are aware of something I’m not. Please share? I’m just trying to find ways to reduce the toxic load for myself and others. Thanks!

      Oh, I’m not discounting their need or efficacy.

      I think is absolutely criminal that we are paying to filter out the chemicals and not 3M and DuPont.
