- ... The release and transport of linear perfluorocarboxylic acids (PFCA) within the vadose-zone beneath per- and polyfluoroalkyl substance (PFAS)- and non-aqueous phase liquid (NAPL)-contaminated source areas is influenced by multi-phase interfacial retention phenomena. Conceptually, interfacial adsorption results in retardation of PFCA velocities in subsurface multiphase systems. However, site hydroc ...
