In 2019, the Vermont legislature passed Act 21 requiring all public community and non-transient non-community drinking water systems to monitor for PFAS. The interim standard for the 5 regulated compounds—PFHpA, PFHxS, PFNA, PFOS, and PFOA—is 20 ppt.
The EPA has not yet set federal standards for PFAS in drinking water.

Lawsuit against PFAS manufacturers
The State of Vermont is proceeding with lawsuits against 3M, DuPont, and others for the manufacturing and distribution of PFAS chemicals and PFAS-containing products in Vermont. Click here for information from the Attorney General.
While any potential settlement is at least 3-5 years away, there may be an eventual opportunity for public water systems to recoup costs related to PFAS monitoring and treatment. At this point, we are advising you to document costs and save invoices from any and all sampling, lab analysis, investigation, and treatment.
