TRAVERSE CITY, Mich. (AP) — Drinking water from nearly half of U.S. faucets likely contains “forever chemicals” that may cause cancer and other health problems
......
The synthetic compounds known collectively as PFAS are contaminating drinking water to varying extents in large cities and small towns — and in private wells and public systems
......
The U.S. Environmental Protection Agency in March proposed the first federal drinking water limits on six forms of PFAS, or per- and polyfluorinated substances, which remain in the human body for years and don’t degrade in the environment. A final decision is expected later this year or in 2024.
But the government hasn’t prohibited companies using the chemicals from dumping them into public wastewater systems
.....
report was based on samples from taps in 716 locations, including 447 that rely on public supplies and 269 using private wells.
The samples were taken between 2016 and 2021 in a range of locations — mostly residences but also a few schools and offices.
......
Scientists tested for 32 PFAS compounds — most of the ones detectable through available methods. Thousands of others are believed to exist but can’t be spotted with current technology
......
Positive samples contained as many as nine varieties, although most were closer to two.
......
The heaviest exposures were in cities and near potential sources of the compounds, particularly in the Eastern Seaboard; Great Lakes and Great Plains urban centers; and Central and Southern California. Many of the tests, mostly in rural areas, found no PFAS.
......
Based on the data, researchers estimated that at least one form of PFAS could be found in about 45% of tap water samples nationwide.
