Quick Answer
Is PFAS in drinking water a real concern in Vermont?
Yes — Vermont is home to one of the earliest and most significant civilian industrial PFAS contamination crises in the United States. Saint-Gobain Performance Plastics' manufacturing facility in Bennington, VT contaminated the town's water supply and hundreds of private wells with PFOA at extremely high levels, making Bennington one of the most studied PFAS contamination sites in the country.
Where does PFAS come from in Vermont?
Saint-Gobain's Bennington facility — which manufactured PFAS-coated industrial tape and other products — emitted PFAS through stack emissions and direct discharge for decades. PFOA contaminated the Bennington municipal water supply and spread to hundreds of private wells across Bennington and North Bennington. Vermont also has additional PFAS concerns from the former Ethan Allen Firing Range and other industrial sites.
What should Vermont residents know?
Bennington and North Bennington residents face one of the most acute documented PFAS exposures of any U.S. community. Vermont set its own MCL of 20 ppt (sum of 6 PFAS) in 2020 and has provided extensive health follow-up including blood testing for Bennington residents. Vermont also has the highest private well density per capita of any northeastern state — approximately 50% of Vermont residents use private wells — making well testing especially important.
Key Facts
| EPA MCL (PFOA/PFOS) | 4 ppt — effective April 2024 |
| Vermont MCL | 20 ppt (sum of 6 PFAS) — adopted 2020 |
| MCLG | Zero |
| Primary contamination source | Saint-Gobain Bennington manufacturing facility (PFOA industrial emissions) |
| Private well risk | ~50% of Vermont residents use private wells — highest rate in Northeast; statewide testing encouraged |
| State response | State-funded blood testing, private well testing, and filtration for affected Bennington residents |
| State regulator | Vermont Department of Health and Agency of Natural Resources |
| Health effects | Cancer (kidney, testicular), thyroid disruption, immune effects, developmental toxicity |
| Effective treatment | GAC (installed in Bennington municipal system) or RO; Vermont has provided filtration to affected well owners |
Why PFAS Matters in Vermont
Vermont's Bennington PFAS contamination case has been one of the most closely studied in the country. Saint-Gobain's manufacturing emissions spread PFOA and other PFAS across a wide area of southwestern Vermont, contaminating both the municipal water supply and hundreds of private wells. Blood testing of Bennington residents revealed elevated PFAS levels, prompting state-funded health monitoring. The Vermont Department of Health and Agency of Natural Resources have been among the most engaged state agencies in PFAS response nationwide. Vermont adopted one of the earliest state PFAS MCLs and has conducted extensive private well testing and remediation.
Historical Context
Bennington's Saint-Gobain contamination became a reference case for industrial PFAS emissions (as distinct from the military AFFF pathway). The facility's PFOA emissions affected a largely rural community with limited resources to respond, drawing national media attention and advocacy support. Vermont's aggressive response — including state-funded blood testing, private well testing, and filtration installation — became a model for state PFAS victim support.
Vermont PFAS Regulation
State MCL — Stricter Than Federal
20 ppt for the sum of 5 PFAS compounds — adopted 2020, predating the federal rule.
Vermont DOH adopted a 20 ppt limit for the sum of 5 PFAS compounds in 2020, making it one of the first states with a PFAS standard. The state's contamination is centered on Saint-Gobain Performance Plastics manufacturing in Bennington — one of the first major civilian PFAS contamination events documented in the U.S. (2016). Vermont has provided bottled water, whole-home filtration, and utility treatment systems to affected residents and has been a model for state PFAS response programs.
What Are PFAS (“Forever Chemicals”)?
PFAS are a family of over 12,000 synthetic chemicals used in non-stick cookware, stain-resistant fabrics, food packaging, and AFFF firefighting foam. Their carbon-fluorine bonds do not break down in the environment or the body — hence the name “forever chemicals.” AFFF used at military bases is the single largest source of PFAS in U.S. drinking water.

Bennington and North Bennington residents, and rural private well users in Bennington County and throughout southwestern Vermont, face the highest risk. Vermont's ~50% private well usage rate makes it especially important for rural residents statewide to test their wells for PFAS.
Residents near military bases with AFFF use history
Private well owners near military or industrial sites
Pregnant residents and families with young children
Residents in communities with documented PFAS detections
Anyone who has consumed water above 4 ppt for an extended period
Residents near airports, fire training areas, or industrial manufacturers
How to Check Your Situation in Vermont
- 1
Identify your water utility using the ZIP lookup below or by browsing the Vermont utility directory on this site.
- 2
Review your utility's Consumer Confidence Report (CCR) — it must report PFAS monitoring results under UCMR5 and the new MCL.
- 3
Check the EPA's ECHO database for your utility's monitoring history. Look for PFAS, PFOA, PFOS, and related compound results.
- 4
Contact your utility directly and ask for their most recent PFAS test results and whether they are implementing treatment under the 2024 MCL.
- 5
If you use a private well near a military base, airport, or industrial facility, order a PFAS panel test from a state-certified laboratory. Tests typically cost $150–$400.
- 6
If PFAS is detected above 4 ppt in your source water, install a certified NSF/ANSI 58 reverse osmosis system or an NSF/ANSI 53-certified activated carbon filter rated for PFAS removal.
How to Remove PFAS from Tap Water
Reverse Osmosis (Best)
90–99% removal — NSF/ANSI 58 certified systems only
Certified Activated Carbon
Effective with NSF/ANSI 53 or 58 certification — verify before buying
Boiling concentrates PFAS. Standard pitcher filters and water softeners do not remove PFAS. Always verify NSF certification before purchasing.
Take Action Now
Look up your Vermont utility's PFAS monitoring history on the PFAS Watchlist below.
If your utility has detected PFAS above 4 ppt, install an NSF/ANSI 58-certified reverse osmosis system at your drinking tap.
Private well owners near military or industrial sites should order a PFAS panel test ($150–$400 at a state-certified lab).
Request your utility's most recent Consumer Confidence Report — PFAS results must be disclosed under the new 2024 MCL.
