We’re proud to share a new publication in “Water Research”: “Characteristics of aqueous film forming foam (AFFF) sites impacted with per- and polyfluoroalkyl substances (PFAS): A 37-site study.”
Co-authored by Poonam Kulkarni, PE, Abigail Cartwright, PE, David T. Adamson, PhD, PE, John Cook, EIT, and Charles J. Newell, PhD, PE, BCEE of GSI, along with Nicolette E. Andrzejczyk and Arun Gavaskar, this article provides insight into PFAS concentration patterns in soil and groundwater at AFFF source zones across the U.S.
Key findings include:
• PFOS and PFOA are the primary contributors in soil, while groundwater concentrations show broader variability
• Maximum PFAS concentrations typically occur in the top one meter of soil
• Median inferred plume lengths for the seven PFAAs range from 220–800 meters
• PFOS, PFOA, and PFHxS contribute 99% of the estimated groundwater exceedance magnitude
