Article Synopsis
- PFAS, particularly PFOS, pose environmental and health risks due to their long-lasting presence, making their fate and transport in sedimentary aquifers complex.
- The study examines how physical and geochemical differences in riparian floodplains affect the movement and concentration of PFOS during changes in river stages.
- Findings highlight that sediment permeability is crucial for predicting PFOS behavior, emphasizing the need to accurately assess aquifer variability to understand PFAS dynamics effectively.
Motivation: Nutrient and contaminant behavior in the subsurface are governed by multiple coupled hydrobiogeochemical processes which occur across different temporal and spatial scales. Accurate description of macroscopic system behavior requires accounting for the effects of microscopic and especially microbial processes. Microbial processes mediate precipitation and dissolution and change aqueous geochemistry, all of which impacts macroscopic system behavior.

Microbial processes in the subsurface can be visualized directly using micromodels to emulate pore-scale geometries. Here, emulated soil micromodels were used to measure transport of fluorescent beads in the presence and absence of the soil ciliate Colpoda sp. under quiescent conditions.
