This Interstate Technology and Regulatory Council (ITRC) online document includes the PFAS Technical and Regulatory Guidance Document, PFAS Fact Sheets and Explainer Videos, Training Module Videos and external tables of data and information prepared by the ITRC PFAS Team. Internal links in the online document will help the reader locate interrelated topics, refer back to key concepts, and locate references, while external links provide connection to the training module videos, see below, on key topics. Finally, the web-based nature of this document lends itself to updating of key information in this rapidly evolving subject. It is the intention of ITRC to periodically update the document as significant new information and regulatory approaches for PFAS develop. The guidance document can be downloaded as a PDF.

The Technical and Regulatory document is designed specifically to support state and federal environmental staff, as well as others (including stakeholders, project managers, and decision makers), to gain a working knowledge of the current state of PFAS science and practice. Developed by a team of over 400 environmental practitioners drawn from state and federal government, academia, industry, environmental consulting, and public interest groups, it also provides a summary of the current understanding of all aspects of PFAS from a broad perspective. While every effort was made to keep the information accessible to a wide audience, it is assumed the reader has some basic technical background in chemistry, environmental sciences, and risk assessment.
