Collectively, the EPA estimates it will cost $1.5 billion per year for America’s 66,000 public drinking water systems to monitor their water for PFAS, inform customers of the results and find ...
The timeline focuses on some perfluorinated compounds, particularly perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) [1] and on the companies that manufactured and marketed them, mainly DuPont and 3M. [2] An example of PFAS is the fluorinated polymer polytetrafluoroethylene (PTFE), which has been produced and marketed by ...

The North Bay is a subregion of the San Francisco Bay Area, in California, United States. The largest city is Santa Rosa , which is the fifth-largest city in the Bay Area. It is the location of the Napa and Sonoma wine regions , and is the least populous and least urbanized part of the Bay Area.
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. [1]
Among locals, the nine-county Bay Area is divided into five sub-regions: the East Bay, North Bay, Peninsula, city of San Francisco, and South Bay. The " East Bay " is the densest region of the Bay Area outside of San Francisco and includes cities and towns in Alameda and Contra Costa counties centered around Oakland .
Cape Fear River Watch published [20] that their research of the NC DEQ permit file [23] indicates that the first PFAS byproducts were likely released from Fayetteville Works in 1976 with the production of Nafion which uses HFPO in production (otherwise known as GenX) and creates byproducts termed Nafion Byproducts 1 through 5, some of which ...
