The scientific community’s understanding of the health and environmental effects of PFAS is evolving at a rapid pace. At the same time, researchers are developing new technologies to assess and remediate PFAS contamination. This section provides the latest updates on developments in PFAS-related science and technology.

Based on information from both human observational studies and clinical data, this study proposed a range for the half-life for PFOA of 0.5 to 1.5 years, which would likely raise many existing regulatory safe levels if all other parameters stayed the same.

Thermal decomposition of high-fluorine content PFAS streams for the disposal of old generations of concentrates of firefighting foams, exhausted ion-exchanged resins and granular activated carbon, constitutes the preferred method for destruction of these materials.

Adsorption onto activated carbon (AC) has been identified as an effective technique to remove PFAS. Adsorption isotherms and breakthrough curves, determined by rapid small-scale column tests (RSSCTs), were studied for eight PFAS and four granular ACs, characterized by different origins, porosities and numbers of reactivation cycles.

These results suggest that suspended particles, often an overlooked vector for PFAAs, can be a dominant pathway for the transport of PFAAs in environments.

The study tested a two-step ‘Concentrate-&-Destroy’ technology for treating over 14 PFAS from a model landfill leachate through bench- and pilot-scale experiments.
