Model-Based Assessment of Adsorption and Diffusion of PFASs through Concrete as Continuous Source of PFASs to the Environment

John Stults, David Lutes, Jinxia Liu, Ian Ross

Per- and polyfluoroalkyl substances (PFASs) are persistent and pervasive contaminants of concern that are frequently introduced into the environment through aqueous film-forming foams (AFFF) on concrete pads. Previously published laboratory results of PFASs diffusion into Portland cement concrete are modeled using an …

Transformation of Polyfluoroalkyl Precursors in AFFF-Contaminated Concrete

David Lutes, Ju Zhang, Lakshya Sethi, Andrew J. Boyd et autres

The contamination of concrete by per- and polyfluoroalkyl substances (PFAS) derived from aqueous film-forming foams (AFFFs) at impacted sites is a newly recognized issue, but the behavior and transformation of PFAS within concrete and in its vicinity remain largely unexplored. In this …

Uptake of Per- and Polyfluoroalkyl Substances into Concrete from Aqueous Film-Forming Foams: Experimental Investigations and Comparison to Field-Impacted Samples

David Lutes, Andrew J. Boyd, Lachlan J. Jekimovs, Brett R. Hamilton et autres

The widespread use of aqueous film-forming foams (AFFFs) in firefighting has led to significant contamination by per- and polyfluoroalkyl substances (PFAS), including in building materials like concrete. This study investigated the initial phase of PFAS contamination in concrete, focusing on factors influencing …

Uptake and transformation of per- and polyfluoroalkyl substances from aqueous film-forming foams in concrete

David Lutes

The significant environmental occurrence of per- and polyfluoroalkyl substances (PFAS)due to their ubiquity in many consumer and industrial products combined with their potentiallyharmful health effects has caused increased attention from regulators in recent years. Asignificant source of PFAS contamination is the utilization …
