Our paper—entitled “Pore-scale modeling of PFAS transport in water-unsaturated porous media: Air–water interfacial adsorption and mass-transfer processes in thin water films“—is recently accepted for publication in Water Resource Research Journal. The paper presents a new pore-scale modeling framework for simulating PFAS transport in water-unsaturated porous media. Pore-scale modeling experiments highlight the importance of two unrepresented physical mechanisms including thin-water-film mass-transfer limitations and surface diffusion for PFAS transport in water-unsaturated soils. These mechanisms potentially significantly impact PFAS transport in the vadose zone and need to be incorporated for field-scale modeling concepts.
