Navigating PFAS in NPDES Discharges, Property Due Diligence and Your PFAS Analytical Toolbox
Lucas Barroso-Giachetti, PE, CHMM, Regional PFAS Technical Lead, Terracon and Paul Jackson, Program Manager, Environmental Compliance & Emerging Contaminants, Pace Analytical
As regulatory frameworks surrounding per- and polyfluoroalkyl Substances (PFAS) continue to evolve, industrial/logistics operators and other entities are under increasing pressure to manage PFAS-related risks within the context of environmental permitting and operational compliance. With decades of combined experience, Terracon and Pace Analytical have supported clients nationwide through expert consulting and laboratory testing services tailored to the unique challenges of PFAS risk management. This presentation will leverage Terracon’s and Pace’s regulatory insight and technical expertise to develop cost-effective, permit-compliant PFAS strategies. Topics will include navigating complex permitting processes—such as National Pollutant Discharge Elimination System (NPDES) permits, stormwater and wastewater discharge requirements—and planning for site-specific investigation and remediation. Terracon will also provide regulatory and risk management perspectives drawn from their extensive experience in many industrial sectors, including airport projects nationwide. Notably, Terracon served as one of the primary authors of the Airport Cooperative Research Program (ACRP) PFAS Source Differentiation Guide for Airports. Pace Analytical will cover the primary soil and water compliance method EPA 1633 along with QA/QC options associated with the method. Pace will also do a deeper dive into the full analytical toolbox and discuss approaches that also utilize ASTM D8421 and EPA 1621 for PFAS analysis.
