Millions in the US may rely on groundwater contaminated with PFAS for drinking water supplies
phys.org
Approximately 71 to 95 million people in the Lower 48 states—more than 20% of the country's population—may rely on groundwater that contains detectable concentrations of per- and polyfluoroalkyl substances, also known as PFAS, for their drinking water supplies. These findings are according to a U.S Geological Survey study published in the journal Science.

    And if you overlay this with a population density map, would they be the exact same? The hot spots are just the major US cities.

      There is a large chunk of dark red nearish to me on this map that could be described as one of the least inhabited parts of the state (state forest + wildlife refuge).

      Though the groundwater level is probably rather high there so that might mean less chance for it to be filtered out through the soil.
