Tests of 27 private wells in a neighborhood just outside the southeastern border of the former Brunswick Naval Air Station, Maine, showed no evidence of harmful contamination by perfluorinated compounds (PFCs), a class of chemicals that has been linked to groundwater contamination at a number of active and closed bases across the country.
The Navy previously discovered contaminated groundwater on several areas of the former air station. The contamination is believed to have been caused by decades of use of firefighting foam.
PFCs were either undetectable or were at levels “well below the health advisory level” for the 27 samples from the first neighborhood tested, Bill Franklin, spokesman for the Navy’s BRAC program, told the Portland Press Herald.
The Navy is preparing to test private wells in a neighborhood outside the base’s northern border later this month.
Suzanne Johnson, the citizen co-chair of the base’s Restoration Advisory Board, was pleased with the results of the first round of testing of private wells.
“We know it hasn’t migrated, so now we need to figure out what to do on the base and how is that [contamination] managed?” Johnson said.
Last month, the New York Times reported that DOD’s initial investigation into 664 sites across the nation that potentially have elevated levels of PFCs in their drinking water has been expanded to at least 2,000 sites, most of them on Air Force bases.
