EHS Support Experts to Present at SETAC Annual Meeting

Three members of the EHS Support Sediment and Risk-Assessment Group will be presenting virtually at the SETAC North America 42nd Annual Meeting this November 14-18.

On Monday, November 15, Chrissy Peterson, Sediment & Risk Assessment Group team manager and Toxicology & Human Health Risk Assessment team leader, will be co-chairing the session “Background: Soil, Sediment, Groundwater, Surface Water & Air – Cleanup Site Risk Assessment & Remedial Decision Making.” This session will include presentations regarding how different entities define and establish soil, sediment, groundwater, surface water, outdoor-air, and indoor-air background. This session also explores methods that can be used to determine media-specific background concentration, including more commonly used methods such as soil background studies and statistics, as well as more complicated methods such as geochemical evaluations and environmental forensics.

Peterson will also be giving a lightening talk in this session on the importance of ambient air data in evaluating potential intrusion of vapors to indoor air that is based on her on-demand presentation: “Ambient Air Data: Key Data Tool for Risk Management in Vapor Intrusion Assessment in California.”

Sam Parker, Ph.D., Sediment & Risk Assessment Group growth manager and Water Quality Compliance strategic lead, will be presenting “Empirical Bioavailability Modeling of Aquatic Fluoride Toxicity – Considerations for Site-Specific Values.” This study used empirical bioavailability models to better predict fluoride ecotoxicity in freshwater and applied those models to develop robust preliminary fluoride criteria. Our approach considered hardness, alkalinity, and chloride toxicity modifying factors to better understand site-specific exposure conditions to aquatic receptors in surface water and pore water. Parker’s presentation will be available on demand.

On Thursday, November 18, Dana McCue, Toxicology & Human Health Risk Assessment strategic growth lead, will be participating in the Live Q&A session “Contaminants of Emerging Concern and Superfund: What Lies Ahead.” Regarding PFAS and 6-PPD, two contaminants of emerging concern that have seen significant new and ongoing regulatory (or other) developments, this session will bring together scientists, regulators, legal experts, and stakeholders on the forefront of PFAS and 6-PPD issues to present forward-looking perspectives of how these compounds will be managed. During the session, she will provide a summary of her on-demand presentation, “Screening Assessment Framework to Assign Relative Risk to PFAS: An Approach to Understand and Assess PFAS Mixtures.”

The relative-risk model is just one of several science-based tools EHS Support has developed to support our clients in response to regulatory requests associated with PFAS at their sites.
