"Most people have heard of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) because they have been the focus of regulations and water testing for years. TFA is different," said Siwei Gu, a postdoctoral researcher in NJIT's Emerging Contaminants Research Laboratory and lead author of the study.

Researchers at the New Jersey Institute of Technology have found trifluoroacetic acid (TFA) in 86.7% of 113 samples of tap water and bottled beverages collected in New Jersey in what is called the first statewide monitoring study of ultra-short-chain PFAS in the U.S. Out of 70 tap-water samples, TFA, a byproduct of HFO-1234yf and other f-gases, was detected in 91.4%, with concentrations ranging 74 to 1360ng/L, and a mean of 573ng/L.
