TFAs are here forever. Short term risks seem minimal. The long-term picture is murkier and more concerning. TFA’s extreme persistence (no natural degradation in terminal sinks like oceans or deep aquifers) means accumulation is effectively irreversible. Sticking with TFA-forming refrigerants locks in decades of accumulation for short-term gains in global warming potential (GWP).

Rethinking Forever Chemicals
While the phrase “forever chemicals” captures attention, it does not accurately reflect the chemical diversity or biochemical behavior of PFAS as a class. The phrase succeeded in raising awareness. But the future of PFAS management belongs to science-driven nuance, not oversimplification.
EPA to keep MCLs for PFOA, PFOS
EPA is announcing its intent to extend compliance deadlines for PFOA and PFOS, establish a federal exemption framework, and initiate enhanced outreach to water systems, especially in rural and small communities, through EPA’s new PFAS OUTreach Initiative (PFAS OUT).
April 2025 EPA moves to combat PFAS in ethe environment
With this approach, EPA will provide the foundation and investment necessary for a toolbox that will help states and communities dealing with PFAS contamination.
USEPA 2024 PFAS NPDWR
As water testing capabilities improve, and as more PFAS contamination circulates through the ecosystem, it is simply a matter of time until ALL UTILITIES are affected by this rule. This will significantly impact the cost of municipal water.
WQA can test to 1 ppt of PFAS
The Water Quality Association’s Laboratory is now accepting requests for reduction testing of PFOA, PFOS and other PFAS compounds with detection limits down to 1 ppt (parts per trillion).
