OAK BLUFFS – Testing of well water on Martha’s Vineyard near the Island’s airport, will continue, according to a report in the Vineyard Gazette.
The move comes after Per and Polyfluoroalkyl (PFAS) were discovered in residential wells.
The contamination was presumably caused by firefighting foam used at the airport. A testing company determined that 13 wells among 96 tested were positive for elevated levels of the contaminant and six posed an immediate health hazard.
The tests were conducted in January, most of the contamination was found in locations south of the airport.
To mitigate the problem, the Airport is installing and monitoring filtration equipment that reduces the amount of PFS in the water. The systems cost about $4,000 each. Officials on the Island are still trying to determine if the contamination may have reached the Island aquifer.
