The New Hampshire Department of Environmental Services found contaminated groundwater at an old landfill in Merrimack, N.H., which is positioned on a 25-acre parcel near the Merrimack Transfer station.
At least one of the wells at the landfill had a PFOA level of 2,200 ppt, and eight out of the 10 monitoring wells near the landfill detected PFOA levels above 100 parts per trillion.
The state has been conducting an ongoing investigation of its water contamination, and these contamination findings have triggered state officials to sample another round of private well water to determine the severeness of the issue.

Groundwater contamination has been discovered at the former town landfill, prompting state officials to begin another round of private well sampling to determine the extent of the problem now facing several communities in southern New Hampshire.
As part of the state’s ongoing water contamination investigation, elevated levels of perfluorooctanoic acid (PFOA) have been detected at the old landfill in Merrimack, which is situated on a 25-acre parcel near the existing Merrimack Transfer Station on Fearon Road.
Jim Martin, public information officer with the New Hampshire Department of Environmental Services, announced Tuesday that eight out of 10 monitoring wells adjacent to the landfill detected PFOA at levels above 100 parts per trillion, the threshold set by DES to begin distribution of bottled water.
