Robert Mueller’s testimony isn’t the only important event happening Wednesday. The House is holding hearings on industry’s Big Tobacco-style campaign to suppress data on the health effects of #PFAS. Bucky Bailey (pictured below) is the first witness. images.app.goo.gl/M4TofNt2NZPGNK…? 1/
Bucky is not the only American touched by #PFAS. More than 99% of us have #PFAS—chemicals linked to cancer, thyroid disease, immune suppression, reduced penis size, low birth weight—in our blood. Also some of these health effects occur at general-population levels of exposure. 2/
But Bucky’s story is particularly illuminating when it comes to certain chemical giants’ willingness to put profits above the wellbeing of ordinary people. Bucky’s mother, Sue, worked at a DuPont plant in WV, which manufactures Teflon, using PFOA (part of the PFAS family). 3/

Soon, the House will consider adding #PFAS to the hazardous substance list under #Superfund. Here’s why that matters.

A THREAD.

#PFAS are a group of chemicals that have been used for decades in a wide variety of industrial, consumer, and military applications. @EWG’s contamination map (updated today!) has identified over 700 sites where PFAS has been detected.

@ewg #PFAS chemicals are largely unregulated and there are very few reporting requirements, so no one really knows everywhere where #PFAS have been released. Currently there are no federal limits on how much PFAS can be released into air or water or where it can be disposed.

The epicenter of yesterday’s #earthquake was near California’s China Lake Air Naval Station, the groundwater beneath which is contaminated with one of the highest levels of toxic #ForeverChemicals (#PFAS) ever detected in the US, if not the world. 1/ mcclatchydc.com/latest-news/ar…
Specifically, the groundwater beneath China Lake station contains 8 million ppt #PFAS, 114,000 times higher than the @EPA’s safety guidelines for some #PFAS drinking water. My question is this: How will the seismic activity affect the movement of groundwater? 2/
Is anyone investigating whether the quakes are causing groundwater highly polluted with #PFAS—chemicals linked to cancer, thyroid disease, low birth weight, immune suppression, reduced penis size, and lower sperm count—to migrate into aquifers & wells supplying drinking water? 3/

For those studying, tracking #PFAS pollution, what @j_g_allen has called the #foreverchemicals -- I wanted to offer some key resources about the relationship btwn the atom bomb and their early research & development w/ the Manhattan Project. An #envhist thread.

2. In 1947, the Manhattan District wrote up the history of their fluorocarbon work in support of the K-25 gaseous diffusion plant at Oak Ridge: see Vol I Book VII, since declassified and w/ the US DoE. Appendix G explains the fluorocarbon and Teflon work:

3. Joseph H. Simons, who's eponymous process, The Simons Process, was used by 3M to make #PFASs, did some of the original research on fluorocarbons that catalyzed the Manhattan Project's development work, tho' his process wasn't used in the bomb project). Here, in the @nytimes:
