Per- and Polyfluoroalkyl Substances Investigation and Remediation

Nicholas Albergo, P.E., Senior Advisor, GHD Services

This presentation provides an update on the development of ASTM E50.04 WK94490, a proposed standard guide for the investigation and remediation of per- and polyfluoroalkyl substances (PFAS) at contaminated sites. The presentation will summarize the scope, intent, and current status of the standard, highlighting how it is designed to support consistent, defensible approaches to PFAS site characterization, risk evaluation, and remedial decision-making. Key elements of the draft guidance—including sampling strategies, data interpretation, conceptual site model development, and alignment with evolving regulatory frameworks—will be discussed. The presentation will also address practical considerations for consultants, site owners, and regulators, and how the standard may be applied across a range of site types as PFAS policies and cleanup expectations continue to evolve.
