Per- and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants known to impact groundwater and surface water. The information surrounding toxicity, laboratory methods, investigations, and remediation strategies is evolving, and the Interstate Technology and Regulatory Council (ITRC) recently published three technical factsheets summarizing current information on PFAS.  The fact sheets are available online.

These fact sheets specifically relate to:
1. History and Use
2. Regulations, Guidance, and Advisories
3. Naming Conventions and Physical and Chemical Properties

Later this month, ITRC plans to finalize three additional guidance documents on Fate and Transport, Site Characterization, and Remediation, which will be made available on the ITRC website.
