Quantification and conceptualization of the transport and fate of PFAS in the subsurface and impact on groundwater resources

As a PhD candidate specializing in soil and groundwater pollution, my research focuses on the fate and transport of Per- and Polyfluoroalkyl Substances (PFAS) in the subsurface, particularly within the unsaturated zone. The PhD project aims to quantify the impact of PFAS-contaminated sites on groundwater resources. We achieve this by collecting soil, ground-, and porewater samples in the field, analyzing relevant parameters in laboratory experiments, and developing a model to estimate the vertical flux at contaminated sites. Special attention is given to PFAS from Aqueous Film Forming Foams (AFFFs) and their movement through Danish soils, such as clayey tills.
