The PFAS Forum II is set to take place on May 2-4, 2022 at the Renaissance Tampa International Plaza Hotel in Tampa, Florida.
The forum will feature two panelists from Verdantas.
Ziqi He, Ph.D., P.E., Senior Technical Consultant, will be presenting What’s New in PFAS Toxicity Since 2016 PFOA/PFOS Health Advisory and Potential Impacts to Federal and State Actions.
Over the past two decades, there have been dramatic changes in “guideline” levels for PFOA/PFOS, primarily as a result of science developments in understanding toxicities of these substances. Since the US EPA established final Health Advisory Levels (HALs) for PFOA/PFOS in 2016, numerous states have further developed their own health-based or regulatory values that are distinct from the EPA’s HALs in terms of screening, notification, action, response, maximum contaminant levels, cleanup levels, etc. Dr. He will examine the regulatory dynamics of PFAS as Emerging Contaminants through comparison/contrast of regulations nationally considering new PFAS toxicity data developed since 2016, with particular focus on the following matters: what to expect with federal Maximum Contaminant Level (Goals) having new toxicity values several orders of magnitude lower than those used for the EPA 2016 HAL, potential development of TCLP levels for PFOA/PFOS as a characteristic hazardous waste, ramifications of UCMR5 data for 29 PFAS with lower detection limits than UCMR3, discussion of which PFAS compounds and HALs the US EPA may develop during the EPA's 2021-2024 Commitments to Action, and communication of major challenges for decision making in impacted businesses and industries.
Nick Barnes, P.E., Environmental Engineer, will be presenting Using Appropriate Conceptual Site Models and Phased Approaches in PFAS Investigations
Information regarding the presence or use of PFAS in certain products and industries is readily available and there are known to be strong connections between PFAS sources and facilities such as airports, wastewater treatment plants, landfill facilities, and certain manufacturing or other PFAS-using industries. How do we know if other facilities have a potential unknown source of PFAS or if a site has been impacted by external sources? Mr. Barnes will explore unsuspected sources, providing a deeper dive into PFAS contribution from industries not directly affiliated with PFAS manufacturing or use. Case studies will be presented to provide a phased and detailed investigation approach to determine the specific conceptual site model for PFAS contamination at unsuspected sites and understand potential PFAS sources from historical or offsite sources.
About the Event
The goal of the PFAS Forum II is to provide an understanding of the environmental issues related to PFAS, educate the environmental/remediation industry and regulatory community on the potential risks from PFAS, as well as discuss regulatory and legal issues, monitoring, treatment, cleanup and disposal technologies.
