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 per- and polyfluoroalkyl substances (PFAS). PFAS 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. Some PFAS are environmentally persistent and bioaccumulative, and may pose human health risks. Recent high-profile cases involving human exposure in the United States have further focused both public and regulatory scrutiny on PFAS.

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 readily accessible 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.

ITRC has developed a series of fact sheets, each synthesizing key information for one of the following core subjects: (1) Naming Conventions and Physical and Chemical Properties, (2) Regulations, Guidance, and Advisories, (3) History and Use, (4) Environmental Fate and Transport, (5) Site Characterization Considerations, Sampling Precautions, and Laboratory Analytical Methods, (6) Remediation Technologies and Methods, and (7) Aqueous Film-Forming Foam (AFFF). The first three fact sheets were published in November 2017, the second three were published in March 2018, and the AFFF fact sheet was published in October 2018.

Next, the project will produce a 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.
