Sarah Van Glubt, Ph.D., Senior Staff Environmental Engineer at Hart Crowser, a division of Haley & Aldrich, has co-authored an article with Mark L. Brusseau of the University of Arizona for the American Chemical Society’s Environmental Science & Technology journal. The article, Contribution of nonaqueous-phase liquids to the retention and transport of per and polyfluoroalkyl substances (PFAS) in porous media, details a study of the co-contamination by PFAS and nonaqueous-phase liquids (NAPLs) at various sites, especially those used for fire training with aqueous film-forming foams (AFFFs).
The study had three main objectives:
- Delineate the relative significance of specific PFAS-NAPL processes on PFAS retention.
- Investigate the influence of NAPL properties, saturation, and mass-transfer constraints on PFAS retention.
- Determine whether PFAS may impact NAPL distribution through mobilization or dissolution.
