The goal of this project is to produce concise technical resources that will help regulators and other stakeholders improve their understanding of the current science regarding PFAS compounds. Per- and polyfluoroalkyl substances (PFASs) such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are a large and complex class of anthropogenic compounds whose prevalence in the environment have become an emerging, worldwide priority in environmental and human health. Certain compounds are believed to be environmentally persistent, and bioaccumulative, and pose human health risks. Recent high-profile cases involving human exposure in the United States have further focused both public and regulatory scrutiny on PFASs. The scientific community’s understanding of PFAS sources, site characterization, environmental fate and transport, analytical methods, and remediation is growing rapidly. However, there is no central clearinghouse available that presents this information in a manner conducive to those other than subject-matter experts. As a result, there is a gap in the broad technical understanding necessary for informed and expedited decisions by regulators and policy makers. The project will produce a series of six Fact Sheets, each synthesizing key information for one of the following core subjects: (1) History and Use of Environmental Sources, (2) Nomenclature Overview and Physicochemical Properties, (3) Fate and Transport, (4) Site Characterization Tools, Sampling Techniques, and Laboratory Analytical Methods, (5) Remediation Technologies and Methods, and (6) Regulatory Summary. Following these will be the release of a detailed technical-regulatory guidance document and an internet-based training course, which will provide links to pertinent scientific literature, stakeholder points of view, technical challenges and uncertainties, and the necessary breadth and depth not given by the Fact Sheets.
