GREENLAND (AP) — New Hampshire officials have found elevated levels of a potentially cancer-causing chemical at wells near the Coakley Landfill.
Groundwater tests conducted by the Department of Environmental Services and Environmental Protection Agency found perfluorochemicals (PFCs) including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in nine of 20 wells. Officials said Monday the levels ranged from 1 parts per trillion to 1,133 parts per trillion. The groundwater standard for PFOA/PFOS is 70 parts per trillion.
Earlier, eight wells at or near the landfill showed elevated levels of PFCs. The landfill in Greenland and North Hampton is a federal Superfund site.
Along with Coakley, contamination from PFCs, used in Teflon coatings, has been found at several industrial sites in the state including near the Saint-Gobain Performance Plastics facility in Merrimack.
