“Allenstown commissioned Nobis Engineering, a Concord-based firm, to test for the chemicals at its landfill in November after the state last year issued new directives to all landfills, public and private.
Nobis tested three sites at the 165 Granite St. landfill for PFAs. Two detected PFA levels well below the New Hampshire Department of Environmental Services standard of 70 parts per trillion. But one monitoring well detected PFA levels at 210 parts per trillion, three times the limit.
