Characterization of the Nature and Extent of Per-and Polyfluoroalkyl Substances (PFASs) in Environmental Media at DoD Sites for Informed Decision- Making
Abstract
The overall goal of the project was to gain an overview of the PFAS problem within representative DoD sites by performing detailed, systematic investigations on the nature and extent of PFAS contamination at three sites. The purpose was to develop improved general Conceptual Site Models that site managers can use to inform cost-effective PFAS management decisions across the DoD portfolio of PFAS-impacted sites. As part of this objective, this project also aimed to provide verification of PFAS fate and transport processes that have been increasingly documented in controlled lab settings but have yet to be comprehensively investigated at field scale. High-resolution characterization field efforts, along with state-of-the-art analytical methods provided a detailed and unique set of results for three sites: i) NAS Jacksonville, FL; ii) NBVC Pt. Mugu, CA; and iii) NALF Fentress, VA. The spatial patterns in PFAS data were used to develop a Conceptual Site Model for each of the three sites that identifies the relevant transport processes, the potential for migration, and active natural attenuation mechanisms at the site. This can include retardation due to various mechanisms, as well as biodegradation of polyfluorinated compounds which may serve as precursors to PFAAs.
