In late 2014, perfluorooctanoic acid (PFOA) was detected in the Village of Hoosick Falls public drinking water supply wells at levels higher than the recommended US EPA advisory level. Subsequent testing also identified PFOA in private wells in the Town of Hoosick. Following the installation of water filtration units, all municipal water supply testing results have indicated non-detectable levels of PFOA since March 13, 2016.
Perfluorooctanoic acid is a man-made chemical used to make non-stick and other household products that are resistant to water, grease, or stains. The chemical is also used in Teflon coating and manufacturing processes.
In the Hoosick area, PFOA-contaminated groundwater is linked to past manufacturing sites throughout the town and village. The NYSDEC has identified Saint-Gobain Performance Plastics and Honeywell International as responsible parties for the contamination.
The Hoosick area Superfund sites include Saint-Gobain-McCaffrey Street; former Oak Materials-John Street; Saint-Gobain-Liberty Street; Hoosick Falls Landfill; and Alexander Schmigel Property. Investigative work is also being performed at potential Superfund sites, or “P” sites, which include Oak Materials-River Road; Interface Solutions; former Dodge Machine; Allied-Signal Laminate Systems-Mechanic Street; and former Oak-Mitsui on First Street.
