Per- and polyfluoroalkyl substances (PFAS) are a group of over 10,000 synthetic chemicals known for their persistence, mobility, and adverse health effects, including bioaccumulation and carcinogenicity. Their widespread industrial use and environmental persistence have led to global contamination, particularly threatening groundwater resources. Despite regulatory restrictions, remediation remains a major challenge due to PFAS resistance to conventional degradation processes. This study, inspired by Newell et al. (2021), investigates the potential application of in situ air-sparging – a technique historically used for volatile organic compounds – for the remediation of PFAS-contaminated groundwater. PFAS behave as surfactants and exhibit strong partitioning to air-water interface, that induces their adsorption into rising gas bubbles generated during air-sparging.
