ITRC PFAS Roundtable

Sponsored by: Interstate Technology and Regulatory Council

This fourth PFAS Roundtable Session offers a unique opportunity to interact directly with experts from the ITRC PFAS Team from around the country on several topics: Human and Ecological Health Effects, Site Risk Assessment, Regulations, Risk Communication and Stakeholder Perspectives. Participants are requested to submit questions in advance of the event to be addressed during this extended Question and Answer discussion with expert panelists. The session is intended to be tailored to the specific needs of its participants, with the expectation that the participant will have a basic understanding of these topics prior to attending the Roundtable Session.

Per- and polyfluoroalkyl substances (PFAS) constitute a large family of fluorinated chemicals, exceeding several thousand in commercial use or the environment that vary widely in their chemical and physical properties. The persistence and mobility of some PFAS, combined with decades of widespread use in industrial processes, certain types of firefighting foams, and consumer products, have resulted in their being present in most environmental media at trace levels across the globe. PFAS have only recently come to the attention of investigators and the public in large part due to the fact that until the early 2000s analytical methods to detect low levels of PFAS in the environment were available only in a few select research institutions. It was not until the early 2010s that these methods to detect a limited number of PFAS became widely available and had detection limits in water low enough to be commensurate with levels of potential human health effects. Toxicological studies have raised concerns regarding the bioaccumulative nature and potential health concerns of some PFAS. As a result, our understanding of PFAS and the risks they may pose is rapidly evolving.

This Roundtable Session is based on the following ITRC-produced resources:

  • A series of fact sheets that synthesize key information about PFAS science. In particular for this webinar, the Regulations fact sheet, the Human and Ecological Health Effects and Risk Assessment fact sheet, the Risk Communication fact sheet, and the Stakeholder Perspectives fact sheet are available resources. The fact sheets were published in 2020.

  • A web-based technical and regulatory guidance document published by the ITRC PFAS Team in April 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. Limited small changes and some references were added to the document in September 2020 to address a range of quickly changing topics. In 2021, ITRC plans to update the technical and regulatory guidance document with new information and regulatory approaches that become available to address the evolving understanding of these contaminants. The document is supported by external files, including a regularly updated tabular summary of PFAS water and soil values used by various regulatory agencies across the United States.

  • 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 2,550 attendees through March 2020. In 2020 an additional 500 people attended virtual workshops. In 2021, the Team plans to provide additional online training resources. More information will be available on the ITRC Training page.

The target audience for this guidance and Roundtable Session is:
  • state and federal environmental staff working on PFAS-contaminated sites
  • Other project managers and decision makers
  • Stakeholders who are involved in community engagement

As a participant in this Roundtable Session you should learn more about:
  • PFAS Regulations
  • Human and Ecological Health Effects
  • Site Risk Assessment
  • Risk Communication
  • Stakeholder Perspectives

Participants are highly encouraged to review the Guidance Document (https://pfas-1.itrcweb.org - specifically Sections 7, 8, 9, 13 and 14), the Water and Soil Values and Basis for PFOA and PFOS Values tabular summaries (https://pfas-1.itrcweb.org/fact-sheets/), and review the associated ITRC video training modules prior to attending the Roundtable Session:


Archives of past Roundtable Sessions are available on the CLU-IN website and Q&A Digests are available on the ITRC PFAS Roundtable Training page (https://www.itrcweb.org/Training/Roundtables).

To assist the panelists in preparing for the Roundtable Session, we request that you provide your questions for the following topics:
  • PFAS Regulations
  • Human and Ecological Health Effects
  • Site Risk Assessment
  • Risk Communication
  • Stakeholder Perspectives

Please provide your questions no later than May 18 so that the ITRC PFAS team can prepare for the Roundtable Session. If you have additional questions after registering, please email them to training@itrcweb.org
