PFAS (Per- and polyfluoroalkyl substances) Information Page

In response to PFAS contamination in Vermont's environment, Act 21 (S.49), an act relating to the regulation of polyfluoroalkyl substances in drinking and surface waters, was passed by the Legislature and signed by Governor Scott in May, 2019.  This law established an interim standard of 20 parts per trillion of detected PFAS compounds in Public Community and Non-Transient Non-Community Water Systems. The act required PFAS monitoring to be conducted by December 1, 2019. The act also required that ANR file with the Secretary of State by February 1, 2020 a revision of the Water Supply Rules to include a Maximum Contaminant Level for five PFAS compounds. 

If PFAS compounds are found above the interim standard, then water systems will be required to protect public health through public notice, over a short term plan and a long term plan. The purpose of the short therm plan is to protect public health quickly so that a system can have the required Do Not Drink public notice lifted, while a long-term plan is developed. The public notice will direct Public Water Systems to obtain alternative water. 

Act 21 of 2019 directed the Agency to investigate and publish an advance notice of proposed rulemaking of PFAS as a class or subclass.  The notice can be found here. The public informational meeting was held on October 16,  2020.  The comment period will run until November 16, 2020. Please send comments to ben.montross@vermont.gov and include “Regulation of PFAS as a Class” in the subject line.
