Per- and polyfluoroalkyl substances (PFAS) represent an emerging global problem due to the increasing contamination of water resources, especially in firefighting training areas used by emergency services. For this reason, the EU has introduced regulations on PFAS concentration limits in drinking water for all member states. PFAS have various significant properties, such as high thermal stability, high surface activity and hydrophobic and oleophobic properties, which have led to their widespread use in numerous industrial sectors since the 1950s. Many of these substances are so called PFAS precursors, which are capable of partial transformation, breaking down to form a perfluorinated terminal substance.
