Most of the attention on PFAS has focused on a handful of legacy substances—such as PFOA and PFOS—which are no longer manufactured in the U.S., Europe, or Japan. In the U.S., major manufacturers voluntarily phased out manufacture of these substances beginning in the early 2000s.
As a result, blood levels of legacy PFAS have declined dramatically, according to CDC data. In their place, industry has developed new short-chain PFAS chemistries, which:
- Have been thoroughly reviewed under EPA’s TSCA New Chemicals Program
- Are supported by robust health and safety data
