Firefighting foams are a major source of environmental contamination with PFAS, a group of chemicals known as 'forever chemicals' because they are so hard to remove from the environment once they are there. Now US scientists have developed a way to help break down these chemicals taking a step towards solving a major challenge for PFAS pollution. The process uses a combination of treatments, which have shown limited ability to break down PFAS separately. In real-world scenarios using firefighting foams, the tandem treatments were able to break the PFAS chemical bonds, a key step in decontamination.
