About PFAS contamination in Bennington

## Summary Bennington's municipal water system earned an A grade for PFAS contamination, meaning the water currently meets federal drinking water standards. No concentrations were reported above detectable levels for any of the 15 PFAS compounds tested, including HFPO-DA, which carries an EPA limit of 10 parts per trillion. None of the tested compounds exceeded their respective federal limits. The contamination source in the area is known — the former ChemFab / Saint-Gobain fabric manufacturing plant.

## What the data shows Fifteen PFAS compounds were tested in the Bennington Water Department's system, and none returned reportable concentrations. This includes both compounds with established federal limits, such as HFPO-DA (limit: 10 parts per trillion), and the 14 additional compounds for which no federal limit has yet been set. Because concentrations were not reported, they are either below detection thresholds or absent entirely. Only one water system serves the city, and it received the same A grade across all tested compounds.

## What residents should know While current test results are reassuring, residents should be aware that the contamination plume from the Saint-Gobain facility is described as ongoing and expanding, meaning conditions could change. A legal settlement with Saint-Gobain has been reached, which may provide resources related to remediation and affected residents — contact the Bennington Water Department or Vermont's Agency of Natural Resources for details on eligibility and current monitoring. Residents are encouraged to check directly with the Bennington Water Department for the most up-to-date testing results and any new developments related to the plume.

About this summary: Narrative text on this page was drafted by an AI model (claude-sonnet-4-6) from EPA UCMR 5 data and reviewed before publication. The numeric data above is reported by water utilities directly to the EPA. If you spot an error, email data@checkyourwater.org.

What Bennington residents can do

Bennington's water meets federal PFAS standards based on EPA UCMR 5 testing. To stay informed:

  • Read your utility's annual Consumer Confidence Report (CCR) — request a copy if you don't receive one.
  • Sign up for water quality alerts from your utility.
  • If you're on a private well, get it independently tested for PFAS.
  • Reduce PFAS exposure from non-water sources: avoid non-stick cookware, stain-resistant fabrics, and grease-resistant food packaging.
