Perfluoroalkyl substances (PFAS), which are linked to cancer and liver damage, were used in a number of products, including Teflon and Scotchgard. PFAS take such a long time to break down in the environment that they are described as "forever chemicals."
David Andrews, a senior scientist at the Environmental Working Group (EWG), which just issued a report about widespread PFAS pollution in the United States water supply, told Reuters, “It’s nearly impossible to avoid contaminated drinking water from these chemicals.” From the article:
Of tap water samples taken by EWG from 44 sites in 31 states and Washington D.C., only one location, Meridian, Mississippi, which relies on 700 foot (215 m) deep wells, had no detectable PFAS. Only Seattle and Tuscaloosa, Alabama had levels below 1 part per trillion (PPT), the limit EWG recommends.
In addition, EWG found that on average six to seven PFAS compounds were found at the tested sites, and the effects on health of the mixtures are little understood. “Everyone’s really exposed to a toxic soup of these PFAS chemicals,” Andrews said.

In case you weren’t panicking enough about the way that ambient environmental factors might be surreptitiously destroying your body, the EPA decided that right now would be a great time to change the rules about how they calculate the risk associated with mercury and other toxic metal factory byproducts. From The New York Times: The new […]
Lockdowns have improved air quality in major cities around the world, per nitrogen dioxide measurements mapped here by Steven Bernard. Most cities, anyway. Data source: ESA Sentinel 5 Data was processed by Descartes Labs showing average pollution levels from Mar 1 to Apr 5 2020, compared with the same period last year. Data was brought […]
Say goodbye to America’s wetlands and streams. Say hello to new rivers of pollution, and parking lots where cattails, frogs, and minnows once were.
A guy on the Apple discussion forum started a thread titled, “Why do your Charger Cables have the lifespan of a housefly?” That question is probably enough to elicit a whole bunch of head nods from virtually everyone reading this, whether you’re an iPhone user, an Android owner or have virtually any device that needs […]
For all their power and capabilities, image editing software isn’t like sitting down to play a video game. You aren’t there to have fun. You’re likely looking to make a few minor tweaks to an image to make it ready to be shared, then you move on with satisfaction in a job well done. If […]
This is truly a golden age for fans of a big ginormous TV screen. Not too long ago, to buy a television over 40 inches usually meant wheeling one of those massive Mitsubishi or Toshiba projection monoliths into your home, consuming a vast portion of any room at a cost of potentially $7,000 to $8,000.
