Comparison of estimated PFAS soil-porewater concentration ratios obtained with different air-water interfacial areas to measured values.

Method PFOS PFNA PFDA PFUnDA PFTDA
Measured (Brusseau and Guo, 2022) 28.9 7.9 37.5 128 233
GSSA-based linear 10 3.8 13.8 41 175
Corrected AQITT-based linear 27.2 8.7 37.8 94 259

PFOS = perfluoroctane sulfonic acid; PFNA = Perfluorononanoic acid; PFDA = Perfluorodecanoicacid; PFUnDA=perfluoroundecanoic acid; perfluorotridecanoic acid (PFTDA). Details on parameters used for the calculations are presented in Brusseau and Guo (2022).
