Monitoring of PFAS, Including TFA, Begins Under EU Drinking Water Directive
As of January 12, member states must measure either total PFAS, including TFA, or the sum of 20 PFAS, with limits of 0.5mcg/L and 0.1mcg/L, respectively. The European Commission announced on January 12 that, under new rules in the EU’s recast Drinking Water Directive, member states must begin monitoring “in a harmonized way” per and polyfluoroalkyl substances (PFAS) levels […]

Study Puts Annual Cost of Removing PFAS from the Environment in Europe, Including TFA, at €100 Billion
The cost of removing PFAS (per- and polyfluoroalkyl substances) from the environment in Europe, including “emerging” PFAS like f-gas by-product trifluoroacetic acid (TFA), would be €100 billion ($108 billion) per year, or €2 trillion ($2.2 trillion) after 20 years, according to the “Forever Pollution” study published by a group of journalists and scientists. PFAS, a class of more […]

How Harmful Is TFA?
A large and growing number of studies have reported the rapid proliferation in the environment of trifluoroacetic acid (TFA), a by-product of certain f-gases in the atmosphere (notably HFO-1234yf) as well as the breakdown of certain pharmaceuticals, pesticides and other chemicals. This begs the question: how harmful is TFA to human beings? TFA is an ultrashort-chain […]

Maine to Ban Sale of PFAS Refrigerants and PFAS-Containing HVAC&R Equipment in 2040
Unlike the U.S. EPA, Maine defines PFAS to include some fluorinated refrigerants, including TFA-producing HFO-1234yf. The U.S. Environmental Protection Agency (EPA) does not consider f-gases or their degradation product trifluoroacetic acid (TFA) to be part of PFAS (per- and polyfluoroalkyl substances), or forever chemicals, a category of environmental pollutants. However, the state of Maine takes […]
