To investigate these often-overlooked compounds, researchers analyzed 113 samples, including 70 tap-water samples from across New Jersey and 43 commercially available bottled beverages. Using a specialized laboratory method, they screened for five ultra-short-chain PFAS that can be difficult to measure through conventional testing procedures.

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.
