Water in Vermont.
Vermont's Bennington PFAS contamination from former Saint-Gobain operations remains under active remediation. Significant private-well exposure to natural arsenic across the state.
How Vermont regulates drinking water.
Among the strictest state PFAS frameworks. Vermont MCL of 20 ng/L combined for five PFAS compounds (2020).

The contamination events, regulatory shifts, and major settlements that define how this state thinks about drinking water today.
- 2016
Bennington PFOA contamination from Saint-Gobain identified; emergency filter distribution to hundreds of households.
- 2020
Vermont sets state MCL of 20 ng/L combined for five PFAS compounds.
The actual water you drink.
The physical rivers, aquifers, lakes, and reservoirs that feed Vermont's public water systems. Source quality is the foundation of tap quality — and where the long-term protection fights happen.

Where the contamination comes from.
Every state has a different industrial fingerprint. The industries below are the dominant historical and active contamination sources in Vermont's drinking water systems.
Saint-Gobain Performance Plastics (Bennington / Hoosick Falls NY corridor) PFOA contamination is the dominant PFAS source. Limited heavy industry — most contamination is agricultural or historical.
What state data flags most consistently.
Drawn from EPA SDWIS sampling records, EWG state summaries, and regional regulatory action over the past five years. Read the full deep dive on each.
PFAS (Forever Chemicals)
A class of ~15,000 synthetic chemicals that don't break down. Now regulated for the first time.
Arsenic
A naturally occurring carcinogen. Highest in private wells and the rural Southwest.
Lead
A neurotoxic metal that leaches from old pipes and solder. No safe level for children.
Risk isn't evenly distributed.
Bennington and North Bennington households served by impacted wells face the most-documented PFAS exposure in the state.
~35% on private wells — one of the highest in the U.S.
What's coming for Vermont's water.
Lake Champlain harmful algal blooms (cyanobacteria) increase with warming and phosphorus loading. Intense rainfall increases combined sewer overflows. Wells in flood-vulnerable valleys face contamination risk.
Statewide mandate
Act 66 (2019) requires lead testing in all schools and licensed childcare every three years.
Five questions for your next Consumer Confidence Report.
Your utility is required to send you a Consumer Confidence Report annually. Most are dense and procedural. These are the questions worth following up on for Vermont specifically.
- 1
If I'm in Bennington area, is my well part of Saint-Gobain remediation oversight?
- 2
What is my system's PFAS measured value vs. VT's 20 ng/L combined MCL?
- 3
Has my school posted Act 66 lead testing results?
Most state regulators allow public records requests for the underlying lab reports behind your CCR — your utility should be able to provide them on request.
What's changed in Vermont water law.
Drinking water regulation moves at the state level as much as the federal level. Below are notable recent bills and regulatory actions specific to Vermont.
- 2021
Act 36 — Statewide ban on PFAS in food packaging.
- 2020
VT sets state PFAS MCL at 20 ng/L combined for five compounds.
- 2019
Act 66 — School Lead Testing mandate.
For PFAS: NSF/ANSI P473 or RO. State of Vermont provides POE filtration to confirmed impacted households.
We don't recommend brands — the NSF/ANSI certification number matters more than the name on the box.
