This course will provide an overview of ecological risk assessment for PFAS, including an overview of the fate, exposure, and toxicity of PFAS in ecosystems.
The presentation will focus on our recently released SERDP guidance document “Guidance for Assessing the Ecological Risks of PFAS to Threatened and Endangered Species at Aqueous Film Forming Foam Impacted Sites,” available for download at: https://www.serdp-estcp.org/Program-Areas/Environmental-Restoration/ER18-1614. This guidance provides pragmatic approaches for addressing PFAS ecological risks at AFFF-impacted sites, but is also applicable to sites impacted by other PFAS sources. Although a focus of the guidance is on Threatened and Endangered (T&E) species, the guidance is applicable to non-T&E species as well. In addition, the course will provide a hands-on demonstration of a customizable Microsoft Excel food web and wildlife exposure modeling tool to enable ecological risk assessors to apply the guidance and recommended exposure and effects models to site-specific ERAs. Model outputs consist of an evaluation of the potential for direct effects to aquatic or terrestrial communities and model-predicted concentrations in food webs and wildlife diet items. The ERA Model Tool will be provided in advance of the course so that attendees can follow along with demonstrations on their own laptops (optional).
