An act relating to drinking water standards for perfluoroalkyl and polyfluoroalkyl substances
H.286 would direct the Secretary of Natural Resources to amend Vermont’s Water Supply Rule to tighten drinking water standards for PFAS. The bill requires a maximum contaminant level of zero parts per trillion for six named PFAS compounds: PFOA, PFOS, PFHxS, PFNA, PFHpA, and PFDA. For any other testable PFAS not specifically listed, the bill would require a combined maximum contaminant level of no more than 20 parts per trillion.
The bill is framed as a rulemaking directive rather than an immediate statutory standard, requiring the Secretary to file a final proposed rule by July 1, 2026. The act itself would take effect July 1, 2025, and would affect the Department of Environmental Conservation’s Water Supply Rule, public water systems, and potentially regulated entities involved in water testing, treatment, and compliance. It would likely increase the stringency of Vermont’s drinking water protections and could require monitoring or treatment changes where PFAS are detected.
If enacted, H.286 would amend Vermont environmental policy by compelling the Department of Environmental Conservation to adopt more stringent PFAS drinking water limits through the Water Supply Rule. It would establish a zero-tolerance standard for several specific PFAS chemicals and a 20 ppt cap for other measurable PFAS, affecting state drinking water regulation, compliance obligations for public water suppliers, and potentially remediation or treatment requirements for contaminated systems.
No committee transcript or vote record is available in the provided materials, so there is no documented debate or recorded sentiment to assess. Based on the bill text alone, the measure appears to reflect a precautionary public-health approach to PFAS contamination and drinking water safety.
The main policy issue likely to generate contention is the strictness of the proposed PFAS limits, especially the zero parts per trillion standard for six compounds and the low 20 ppt threshold for all other testable PFAS combined. Potential points of disagreement include the feasibility and cost of compliance for water systems, the scientific basis for setting limits at these levels, and whether rulemaking should be mandated by statute or left to agency discretion. No specific opposing or supporting viewpoints are documented in the provided record.
