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 ...
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 ...

By the 1970s, 3M was aware of the environmental dangers of PFAs [citation needed] and began their "Pollution Prevention Pays", preventing over 2.5 million tons of waste from entering landfills. Since then, 3M has continued to use PFAs in a variety of products, with Scotchgard being the most well known and commercially lucrative. [4]
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]
Plan Bay Area is the long-range Regional Transportation Plan and Sustainable Communities Strategy for the nine-county San Francisco Bay Area.It is the Bay Area's implementation of the Sustainable Communities and Climate Protection Act of 2008, or SB 375, a California law that aims to integrate sustainable strategies to reduce transportation-related pollution and external greenhouse gas emissions.
