Adsorption of Single and Multi-Component Per-and Polyfluoroalkyl Substances (PFAS) at Air-Water Interfaces
… their use in consumer products and fire-fighting foams. The purpose of this study was to investigate the transport and retention of PFAS in groundwater systems, with a particular focus on their adsorption to air-water interfaces under environmentally relevant conditions. Laboratory experiments …

Factors Affecting Fuel Transport of Firefighting Foam
Aqueous film-forming foam (AFFF) used for fuel firefighting contains polyfluoroalkyl substances (PFAS) that have been identified as environmentally persistent and bioaccumulative resulting in phase out of AFFF. Currently, there are no environmentally friendly foams available that can perform at the …

Understanding the nonaqueous partitioning of per- and poly-fluoroalkyl substances (PFAS)
… learning was used, suggesting associations with aqueous film-forming foam (AFFF), landfills, and wastewater treatment plants (WWTP). The limited PFAS treatment technologies in WWTPs contribute to high levels of PFAS in water effluent and biosolids, leading to the re-spreading of contamination. …

Evaluation of stormwater control measures for the removal and fate of legacy and emerging contaminants
… carboxylates were more frequently found in the aqueous phase. Similar to the legacy contaminants, dissolved PFAS were not effectively removed by SCMs. Additionally, there was evidence that PFAS precursors in stormwater transformed into more stable terminal PFAS, which persist in the water and …

Photochemical processes in engineered aquatic systems for remediation of per- and polyfluoroalkyl substances and algae cultivation
… destruction of PFASs. PFASs are a component in aqueous film-forming foam (AFFF) used in fire-training activities and have caused widespread contamination across the U.S. While recent studies have shown promise in UV-sulfite treatment of individual PFASs, little is known of treatment in PFAS …

Evaluation of Nitrification Inhibition Using Sequencing Batch Reactors and BioWin Modeling, and the Effect of Aqueous Film Forming Foam on Biological Nutrient Removal
… for comparison and to ensure reactors were performing as intended. Results suggest that there was some level of continuous inhibition for both NP RWI and PCI reactors, however no sporadic inhibition events were observed. It also appeared that the VIP RWI control reactor experienced some level …
