Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of anthropogenic chemicals. Current information pertains mainly to Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA), and recently perfluorohexane sulfonate (PFHxS), but there are thousands of various PFAS compounds with different American Chemical Society Chemical Abstracts Service (CAS) Registry Numbers. These chemicals are persistent in the environment and humans. They have a negative effect on the health of those individuals exposed to them. In response to the concerns, certain guidelines have been put in place globally, so it is clear what levels of PFAS should exist in water used for specific purposes. Many treatment methods appeared based on the characteristics of PFAS. The most common way to treat PFAS contaminated water is the use of granular activated carbon (GAC) and/or ion exchange (IX) resins. However, problems arise in terms of efficiency. A new absorbent media of MyCelx filtering and polishing has been developed by OLEOLOGY and has been approved (through in-field operations) and accepted Australia wide. The treatment system, utilising MyCelx technology, has lower cost, requires a smaller footprint, and has proven capability to achieve below level of detection for all PFAS and precursors. The National Environmental Management Plan on PFAS (PFAS NEMP 3.0) is to be released soon and indications are more PFAS analytes have been added. OLEOLOGY water treatment systems infused with MyCelx technologies have been deployed and the results tested for eight new analytes including GenX and ADONA.
