PFASs (for polyfluoroalkyl and perfluoroalkyl substances) – are used in products ranging from food wrappers to clothing to nonstick cookware to fire-fighting foams. They have been linked with an increased risk of kidney and testicular cancers, hormone disruption, high cholesterol, and obesity.“PFASs are a group of persistent manmade chemicals that have been in use since 60 years ago,” said lead study author Xindi Hu, a public health and engineering researcher at Harvard T.H. Chan School of Public Health in Boston and Harvard University in Cambridge, Massachusetts.
Once these chemicals get into the water, they're hard to get out, Hu added by email.

“Most current wastewater treatment processes do not effectively remove PFASs,”
.
The study found that PFASs were detectable at the minimum reporting levels required by the EPA in 194 out of 4,864 water supplies in 33 states across the U.S.
Drinking water from 13 states accounted for 75 percent of the unsafe supply, led by California, New Jersey, North Carolina, Alabama, Florida, Pennsylvania, Ohio, New York, Georgia, Minnesota, Arizona, Massachusetts, and Illinois
.
“So the negative effects on immune functions appear to be lasting,” Grandjean said. “Sadly, there is very little that an exposed resident can do, once the exposure has led to an increased amount of PFASs in the body.”

Toxic chemicals in drinking water for six million Americans

PFOS and PFOA are eliminated very slowly from the human body. This means concentrations of these chemicals in the body increase over time if they are continuously consumed in food or water. They have been found in human blood, urine, breast milk and babies' umbilical cord blood. These chemicals have been shown to have some effects, particularly in the liver, at low doses in animal tests. Other effects of PFOS and PFOA noted in testing on laboratory animals include benign tumours and impact on reproduction and development. Nevertheless, the scientific literature on their effects in humans does not give conclusive results.

but unofficially the reverse osmosis systems should due to the filtration process there working on finding out how much they reduce PFASs so I would suggest looking for a RO system
