Beginning in October 2016, 37 scientists and engineers voluntarily collaborated through the National Ground Water Association to develop information on per- and polyfluoroalkyl substances (PFASs) for the broader groundwater community. Using a consensus-driven process that included a public comment period, their efforts were completed toward the end of 2017. NGWA published this PFAS document to assist members and other groundwater professionals who may be tasked with investigating the transport pathways and extent of PFASs in groundwater and surface water, assessing potential risks to receptors, or designing and constructing engineering controls to manage subsurface PFAS contamination. The main purpose of this document is to summarize the current state of knowledge and practice regarding PFAS fate, transport, remediation, and treatment, recognizing that knowledge in this field continues to advance. This document also summarizes current technologies, methods, and field procedures being used to characterize sites and test remediation and treatment technologies.
