Hoosick Falls drinking water: what to know about PFOA
PFOA was found in the village water years ago. The state-ordered carbon filtration system treats it, and there are clear steps for testing your own well.

Years ago, the chemical PFOA was found in Hoosick Falls’ water, traced to past manufacturing at the Saint-Gobain McCaffrey Street site and related properties. In response, New York ordered a full-capacity granular activated carbon (GAC) filtration system for the village water supply, paid for by the responsible companies. It has been treating the water since 2016, and testing has shown PFOA at non-detectable levels coming out of the system.
The response has kept moving. On March 31, 2025, New York announced a new permanent wellfield and transmission line drawing groundwater from outside the contaminated aquifer, while keeping the filtration system in place. The announcement described the new supply as meeting drinking water criteria for the roughly 4,500 people it serves.
If you are on the village system, keep the New York State Department of Health page with your water file so you can find current test results and monitoring updates. If you have a private well in the Hoosick Falls area, New York has installed and maintains point-of-entry treatment systems for affected homes, more than 1,000 as of late 2023. To get a well sampled or ask about a treatment system, call the NY Department of Health at (518) 402-7860.
