This map shows water systems that tested at or above newly established PFAS limits since last year, as of Jan. 11. It’s based on boundaries developed by SimpleLab, a water-testing company. Click on a system to see which pollutants surpassed the limits and how much the most concentrated pollutant exceeded those levels. Points represent systems where the exact boundaries are not available.
Nearly 35 million people get their water from systems that reported high levels of PFAS in at least one test last year. Fixing the problem is costly.
The "forever chemicals" have turned up in water systems large and small, from those serving a few thousand customers to over half a million.
The EPA has released data showing more than 850 water systems reported finding forever chemicals, which are linked to increased cancer risk.
Hundreds of community water systems found at least one of 29 types of PFAS chemicals that exceed the EPA’s new, lower reporting limits.
