Perfluorooctanesulfonate (PFOS) migration from vadose zone sources to groundwater is determined by multiple interfacial retention processes and their dependency on hydrochemistry. This study investigates the impact of air-water mineral-water PFOS transport under different hydrochemical conditions assess adsorption magnitudes feedback dynamics as a function ionic strength. Flow-through experiments were conducted in unsaturated quartz goethite-coated sands equilibrated with background electrolyte concentrations distinguish between goethite-water contributions retardation.

Experimental modeling results reveal that multiprocess causes nonideal transport, plume retardation mass transfer phases relative contribution individual electrostatic interplay driven solution counterions. These findings illuminate sorption emphasize need simulators implementing interdependent influenced water chemistry conditions.
