PFAS Technical and Regulatory Guidance Document

The last full update of this document was September 2023.

Some references were updated in May 2024. For example, USEPA Method 1633 is no longer a draft method; the USEPA MCLs were finalized, and the USEPA PFAS Destruction and Disposal Guidance Version 2 was published.

2024-25: The PFAS Team is working on additional content for PFAS that will be linked to the existing material when published.
