“…PFAS can be filtered out of drinking water using granular activated carbon filters, but they only adsorb loosely to activated carbon and can be displaced by other chemicals at any time (Kucharzyk et al. ). Unfortunately, there is no practical method for removing PFAS from groundwater or surface waters.…”

“…Furthermore, practical and scalable strategies must be developed for removing PFAS from ground and surface waters (Kucharzyk et al. ; Darlington et al. ) and many PFAS compounds that are used in products already on the market must be tested for toxicity.…”

“…Treatment of PFAS-contaminated soil via high temperature kilns is effective, with extremely high temperatures causing PFAS compounds to break down. PFAS can be filtered out of drinking water using granular activated carbon filters, but they only adsorb loosely to activated carbon and can be displaced by other chemicals at any time (Kucharzyk et al 2017). Unfortunately, there is no practical method for removing PFAS from groundwater or surface waters.…”

In this review, we focus on per‐ and polyfluoroalkyl substances (PFAS), synthetic compounds used for a variety of applications, including firefighting foam and manufacturing. Recently, researchers have linked human exposure to PFAS to negative health effects. Hundreds of communities are affected by PFAS contamination, which has raised awareness about the toxicity of these chemicals. Most work has focused on characterizing dangers to humans, and the effects of PFAS on the environment are under‐studied. PFAS contamination of surface water can result in bioaccumulation and biomagnification in fishes. Studies have linked PFAS to lower fitness in fishes, and anglers who consume wild fish can have higher exposure to PFAS compared to the general population. These chemicals remain largely unregulated and the public has been unaware of the extent of contamination and their risk to human health until recently. We review known PFAS contamination of wild‐caught fish, and their possible health risk through angler exposure in the Fairbanks North Star Borough, Alaska. The conclusions and recommendations from the case study can be applied to and are useful for PFAS‐contaminated communities nationwide.

“…The most experimental of the next generation of PFAS treatment technologies are the destruction‐based technologies. Despite the resistance to biodegradation, there are reports throughout the literature of physical and chemical technologies achieving partial or complete destruction of some PFAS (Vecitis et al ; Merino et al ; Kucharzyk et al ; Ross et al 2018). There are several consistent questions associated with reported destruction‐based technologies, such as effectiveness on short‐chain PFAA and polyfluorinated precursors, legitimacy of the reported fluoride mass balances, energy requirements, and secondary water quality.…”

“…As with every other contaminant that has emerged to challenge the remediation community, academic and industry professionals are collaborating globally to research and develop innovative new ways to remove PFAS from water or destroy PFAS altogether. Helpful literature review documents summarizing the progress of PFAS treatment technologies provide a state of the practice assessment, but also highlight that even relevant treatment technologies may have considerable hurdles to handle practical treatment applications at the field‐scale (Vecitis et al ; Du et al ; Merino et al ; Kucharzyk et al ; Ross et al 2018) and the inapplicability of conventional treatment technologies (Appleman et al ; Higgins and Dickenson ).…”
