The ITRC PFAS Team is producing technical resources to 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 are 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, toxicity, regulation, and treatment technologies is growing rapidly, and the ITRC PFAS Team has prepared readily accessible materials to present this information to stakeholders, regulators, and policy makers. These materials can be used to foster development of a broad technical understanding necessary for informed and expedited decisions to address PFAS impacts to human health and the environment.

The materials developed by ITRC and available on the web include:

  • A series of fact sheets that synthesize key information for 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 fact sheets were first published between 2017 and 2018, and updated in 2020. Next, the Team will prepare abbreviated Fact Sheets to summarize information in the technical and regulatory guidance document.
  • A web-based technical and regulatory guidance document published by the ITRC PFAS Team in 2020 that presents the necessary breadth and depth not given by the fact sheets, stakeholder points of view, technical challenges and uncertainties, risk communication strategies, and provides links to pertinent scientific literature. In 2020 and 2021, ITRC plans to publish a risk communication toolkit, and update the technical and regulatory guidance document with new information and regulatory approaches that become available to address the evolving understanding of these contaminants.
  • Online training materials that convey the information presented in the technical and regulatory guidance document. Ten video training modules and brief introductory videos on the topics are posted on ITRC’s YouTube channel. Additionally, the Team provided in-person training workshops to approximately 2,500 attendees in 2018 and 2019. In 2020 and 2021, the Team plans to provide additional online training resources. More information will be available on the ITRC Training page.
