High levels of PFOA found in well near Saint Gobain
MERRIMACK, N.H. (AP) — The New Hampshire Department of Environmental Services says elevated levels of a toxic chemical have been found in groundwater near the Saint Gobain plastics company in Merrimack.
The state says a sample collected from a monitoring well shows perfluorooctanoic acid, or PFOA, at 19,000 parts per trillion. That’s the highest level found in groundwater around the facility.
The current limit for PFOA in drinking water is 70 parts per trillion.
The state says the high level suggests that the potential release of PFOAs happened near the monitoring well. It says more work is needed to assess the source of the release.
