'High Levels Of 'Forever Chemicals' Detected In Northern Virginia Drinking Water,' NPR, Mar 10, 2021.

They're known as "forever chemicals," because they linger in the environment and our bodies ... forever. And new testing by the Environmental Working Group found the cancer-causing chemicals to be present in drinking water in Northern Virginia at higher levels than elsewhere in the D.C. region — and among the highest in the United States.

The chemicals, known as PFAS (short for per- and polyfluoroalkyl substances), have been used in all sorts of products — from carpet to firefighting foam — since the 1940s. In many uses, the chemicals help make materials water repellent or stain repellent. But PFAS chemicals can cause myriad health problems in humans, including increased cholesterol levels, thyroid problems, cancer, and low infant birth weights, according to the Environmental Protection Agency.

The D.C.-based Environmental Working Group tested tap water at 19 locations in Northern Virginia, including Alexandria, Arlington, Fairfax County, Loudoun County, and Prince William County. The samples come directly from taps across the Northern Virginia area," says Sidney Evans, a science analyst with the group who worked on the testing project. Samples were taken at public parks, gas stations, private residences and elsewhere. The results showed the chemicals were present at levels ranging from 5.5 parts per trillion, or ppt, at one site in Fairfax County to 62.4 parts per trillion at a site in Prince William County.

The levels found in some Northern Virginia locations are significantly higher than what the Environmental Working Group found in a round of national testing released a year ago. In that report, PFAS were found in D.C. at 21.7 ppt and in Prince Georges County, Maryland. at 17.8 ppt.. The EPA does not actually regulate PFAS chemicals, so there is no upper legal limit. However the EPA does have a non-enforceable health-advisory recommending PFAS levels below 70 ppt. The PFAS levels found in Northern Virginia are within the range that the EPA considers safe.

But the EPA's level is far too high, according to environmental activists...

Dark Waters - The Story of Teflon: Robert (Mark Ruffalo) reveals the secret history of teflon. Based on the true story. A tenacious attorney uncovers a dark secret that connects a growing number of unexplained deaths to one of the world's largest corporations. While trying to expose the truth, he soon finds himself risking his future, his family and his own life.. there aren’t too many other words for what “Dark Waters” is about: the fact that starting in the early 1950s, Dupont, the most powerful American chemical company, used toxic materials in a number of its products, knowing full well — because of the company’s own research — the disastrous effects those materials might have on anyone who came into contact with them...
