The report, published by the Environmental Working Group, found that 20 cities and regions nationwide – including Washington, D.C., Philadelphia, Miami and Louisville, Kentucky – contained PFAS levels of at least 10 parts per trillion. Forty-three areas, including New York City, Nashville, Las Vegas and Sacramento, had detectable PFAS(polyfluoroalkyl substances) at least 1 part per trillion...
... Only one city, Meridian, Mississippi, which uses well water 700 feet below the surface, found no PFAS, while Tuscaloosa, Alabama and Seattle had levels lower than the 1 part per trillion limit advised by the EWG.
EWG's work expanded on data from an EPA program that ended in 2015, analyzing water samples using an EPA-approved independent laboratory for a larger set of PFAS compounds.
Based on our tests and new academic research that found PFAS widespread in rainwater, EWG scientists now believe PFAS is likely detectable in all major water supplies in the U.S., almost certainly in all that use surface water. EWG’s tests also found chemicals from the PFAS family that are not commonly tested for in drinking water.
EWG’s samples – collected by staff or volunteers between May and December 2019 – were analyzed by an accredited independent laboratory for 30 different PFAS chemicals, a tiny fraction of the thousands of compounds in the family of per- and polyfluoroalkyl substances. An EPA-mandated sampling program that ended in 2015 tested for only a few types of PFAS and required utilities to report only detections of a higher minimal level. The EPA also only mandated testing for systems serving more than 10,000 people, whereas EWG’s project included a sample from a smaller system excluded from the EPA program. Because of those limitations, the EPA reported finding PFAS at only seven of the locations where EWG’s tests found contamination.
PFAS, per- and polyfluoroalkyl substances also known as "forever chemicals," have been linked to reproductive and developmental, liver and kidney, and immunological effects, as well as high cholesterol and obesity.
PFAS compounds remain in food packaging, cookware, and other consumer products. Once released into the environment they do not break down, and they can build up in our blood and organs. Exposure to PFAS increases the risk of cancer, harms the development of the fetus and reduces the effectiveness of vaccines. Biomonitoring studies by the CDC, show that the blood of nearly all Americans is contaminated with PFAS.
An EPA spokesperson told USA TODAY that efforts to address PFAS are "active and ongoing," citing an action plan that would take "important steps" in the detecting and cutting down on PFAS.
Notably, many states' maximum contaminant levels, including Minnesota's current regulations and New York's proposed limits, are far stricter than the EPA guidelines, hovering around the 10 to 20 parts per trillion mark.
The EPA announced last year new methods that increased the number of PFAS chemicals monitored in drinking water to 29.
Interesting link, thanks.

Here is a link to a EWG website where you can search for your area in the 2019 Tap Water Database. I strongly suggest taking a look at a few of the links above, they get into fantastic detail, much to which I'm clueless lol.
So now that I know the PFAS issue with microwave popcorn, I'll probably never eat it again, not much of a change for me since I already stopped eating it years ago.
when you hear popcorn bursting in a bag in your microwave, consider why the oil doesn’t ooze out and the paper doesn’t burst into flames, even when some kernels turn black...
...people who reported eating microwave popcorn had significantly higher levels of four types of PFAS chemicals, according to a study published in Environmental Health Perspectives. The more frequently people ate popcorn, the higher their level of PFAS chemicals in their blood samples.

My dad has been on the same well water for 40 years, and he still has water samples tested each year.
to me its nuts to not check your water on a regular basis.
