About PFAS contamination in Hoosick Falls

## Summary Hoosick Falls' public water system has earned an A grade, meaning the system is currently in compliance with federal PFAS drinking water standards. No compounds were found to exceed federal limits, which is a meaningful milestone for a community that has dealt with significant PFAS contamination in the past. Fifteen PFAS compounds were detected in the water supply, though none at levels that trigger federal action thresholds. The contamination source has been identified as the Saint-Gobain and Honeywell plastics manufacturing plants near the village.

## What the data shows Testing identified 15 PFAS compounds present in the Hoosick Falls Village public water system, including substances such as PFDA, PFBS, and PFTA, among others. For each of these compounds, no concentration was reported because no federal limit has yet been established for them individually. The A grade reflects that no detected compound exceeded an enforceable federal threshold. It is worth noting that the absence of a federal limit does not necessarily mean a compound is harmless — it means regulators have not yet set a specific standard for it.

## What residents should know Residents should be aware that Hoosick Falls has a documented history of industrial PFAS contamination, and while the current grade is encouraging, ongoing monitoring remains important. A legal settlement with Saint-Gobain and Honeywell has been resolved, which may have provided resources for remediation and water system improvements. Contact the Hoosick Falls Village water utility directly for the most current testing results and information about what treatment measures are in place.

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 Hoosick Falls residents can do

Hoosick Falls'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.
