Information from NHDES on PFOA in Well Water


Investigation into Perfluorooctanoic Acid found in Southern New Hampshire Drinking Water


NHDES is investigating the presence of perfluorochemicals (PFCs) in drinking water in the towns of Merrimack and Litchfield, New Hampshire. The investigation was initiated in early March 2016, when Saint-Gobain Performance Plastics notified NHDES that perfluorooctanoic acid (PFOA) was detected at low levels [0.03 micrograms per liter (µg/L) or 30 parts per trillion] in samples taken from four water faucets within their Merrimack facility, which is served by the Merrimack Village District Water System. Information related to the investigation and links for additional information about PFCs will be posted on the webpage.
