Environmental agencies reveal elevated PFOA, PFOS concentrations at former Coakley Landfill
CONCORD — Preliminary results for groundwater samples collected at the former Coakley Landfill in North Hampton and Greenland show elevated concentrations of perfluorochemicals, which include perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS).
The samples revealed PFOA and PFOS concentrations range from 71 parts per trillion to 1,108 parts per trillion. The New Hampshire Ambient Groundwater Quality Standard is 70 parts per trillion.
Municipal and industrial wastes were dumped into the Coakley Landfill from 1972 to 1982, according to the NHDES.
For quality assurance, the results are still pending review from a third-party.
