ABSTRACT

Per- and polyfluoroalkyl substances (PFAS) have rapidly transitioned from emerging contaminants to routinely monitored regulated analytes, fundamentally changing how environmental sampling programs are designed and implemented. As laboratories, utilities, consultants, and regulators expand PFAS monitoring efforts, field sampling practices continue to evolve to meet increasingly stringent data quality objectives and lower reporting limits.

This presentation will provide an overview of current trends in PFAS sampling across drinking water, wastewater, groundwater, surface water, biosolids, and industrial investigations. Topics will include recent developments in contamination control practices, field quality assurance and quality control considerations, sampling equipment selection, and lessons learned from large-scale PFAS monitoring programs. The presentation will also discuss emerging analytical drivers, including EPA Methods 533, 537.1, and 1633, expanding analyte lists, precursor investigations, and the growing importance of defensible sampling practices in regulatory and legal settings.

Attendees will gain practical insight into how PFAS sampling programs are adapting to evolving regulatory requirements while maintaining data integrity and minimizing the risk of cross-contamination in the field.
