PFAS in Source and Ambient Air, Part 5

Why attend this webinar? Air sampling for PFAS is becoming essential for facilities managing destruction processes, manufacturing operations, and vapor intrusion concerns. EPA's updated Destruction and Disposal Guidance (April 2024) establishes new monitoring expectations, while ambient air concerns drive perimeter monitoring requirements.

What you'll learn:

Regulatory Drivers Shaping Air Monitoring Requirements
EPA's April 2024 Interim Guidance on PFAS Destruction and Disposal establishes protocols for stack emissions testing and destruction efficiency verification. Understand compliance obligations for incineration, thermal oxidation, and manufacturing facilities.

Worker Safety and Indoor Air Concerns
NIOSH, CDC, ATSDR, and EPA have grappled with complex challenges regarding worker exposure, indoor air quality, and vapor intrusion. The context of each assessment requires specialized methodologies tailored to specific air environments, specific PFAS, and relevant concentration thresholds. Learn from the research they have conducted to date.

Ambient Air: Background Levels and Atmospheric Transport
Background levels of PFAS are receiving heightened attention, some of which may originate from atmospheric transport, both through wet and dry deposition. This increased focus raises important questions about point source emissions versus background. Discover how these assessments are being carried out.

Construction and Excavation Considerations
Material handling during construction or excavation at contaminated sites can mobilize PFAS-impacted dust and vapors. We'll discuss when air monitoring protects workers and surrounding communities.

Specialized Sampling and Analytical Methods
PFAS air analysis requires techniques beyond standard organic compound methods. We'll compare EPA guidance approaches (OTM-45, OTM-50, Modified Method 0010) and modified standard methods (TO-13A/TO-10A/TO-17), explaining which protocols suit different air matrices and concentration ranges.

Practical Implementation Challenges
The unique physicochemical properties of PFAS complicate air sampling. Learn about breakthrough issues, detection limits, matrix interferences, and quality control considerations specific to air testing.

Who should attend: Industrial facility managers, incineration/thermal treatment operators, environmental health and safety professionals, remediation contractors, and consultants managing PFAS-impacted sites with potential air exposure pathways.
