The objective of this project is to conduct comprehensive reviews of per- and poly fluoroalkyl substances (PFAS) ecotoxicology research, namely research funded through SERDP, along with other peer-reviewed research to concisely synthesize its critical outcomes and make it easily accessible to risk assessors and decision-makers working at PFAS-impacted sites. Based on current decision-making needs and key uncertainties at PFAS sites, there are four key PFAS ecotoxicology topics for this focused synthesis: 

•  PFAS marine aquatic toxicity
• PFAS bioaccumulation
• PFAS mixture ecotoxicity
• PFAS passive samplers 

The outcome will be four peer-reviewed technology transfer reviews and Critical Findings Fact Sheets that provide pragmatic recommendations, and key findings that can directly be applied in site-specific ecological risk assessments (ERA) at aqueous film-forming foam impacted sites. 

The technology in this project is a series of review papers for PFAS ecotoxicology, focusing on information tailored to ERA in a way that provides a streamlined and effective technology transfer approach for SERDP work. These innovative technology transfer efforts go beyond a summary of the research findings, as they synthesize the science within the context of typical ERA practice and policy, providing risk assessors, and other decision makers with pragmatic and focused recommendations in a single, concise document.

The innovative technology transfer approach targeted in this project will highlight critical PFAS ecotoxicology knowledge that will reduce time and effort spent reviewing and debating the research. Moreover, the innovative technology transfer approach can help to avoid overly stringent cleanups because of poorly scoped investigations or ineffective site-specific ERA that do not take advantage of the latest science.
