Trifluoroacetid Acid (TFA) is an omnipresent pollutant in water. This small PFAS molecule is a final breakdown product of PFAS pesticides, some F-gases and other chemicals containing a -CF₃ group. It does not degrade and concentrations are rising irreversibly. The pollution of our water with TFA might be one of Europe's most urgent pollution problems, but authorities hesitate to act. In this position paper we highlight the problem, the sources and what needs to be done in our opinion.
