Its persistence and high mobility also make it challenging to remove through conventional water treatment.

TFA can enter the environment through multiple pathways, including the breakdown of certain fluorinated refrigerants, pesticides and other chemicals. It can subsequently be transported through precipitation into surface water and drinking-water sources. Its persistence and high mobility also make it challenging to remove through conventional water treatment.

PFAS are widely used because they are resistant to heat and chemical extremes, but these same characteristics make most conventional treatment technologies ineffective for PFAS removal or destruction both at contaminated sites (see section 2.3) and for drinking water treatment.
