Report Date:



This guidance document, developed under SERDP to aid the DoD, presents a current state-of-the-practice overview of available methods, best practices, and key data gaps in assessing the potential for risks from exposure to perfluoroalkyl and polyfluoroalkyl substances PFAS for threatened and endangered T and E species at aqueous film forming foam AFFF impacted sites. It is intended to provide clear guidance to quantitatively evaluate ecological risks to PFAS, and enable site managers to make defensible, risk-based management decisions using the best available information and approaches. The guidance presents clear and specific quantitative recommendations for ecological risk assessments. This information is based on amid-2018 to early 2019 review of publicly available information, and the values and recommendations herein should be viewed in context of future additional technical and regulatory information. Accordingly, the approaches and recommendations in this guidance are not intended to be absolute and are subject to change based on new information, site-specific regulatory and scientific considerations, and common sense.
