The primary source of drinking water for tens of thousands of people on Cape Cod has elevated levels of toxic chemicals, according to a new study.
Scientists at Harvard University found that several watersheds on the upper Cape around Mashpee had 40 times more PFAS â known as âforever chemicalsâ because they never fully degrade â than new state rules allow. The compounds, which a growing body of research has found can be harmful in minute amounts, have been linked to cancer, low infant birth weights, and su
HYANNIS – A study released Friday by Harvard University researchers found that conventional testing for per- and polyfluoroalkyl substances (PFAS) found just a fraction of what was actually present in water tested at sampling sites in the Childs River and Quashnet River watersheds in Mashpee, and the Mill Creek watershed in Hyannis.
But the finding no one expected was an additional large amount of PFAS in these three watersheds that had previously gone undetected and was not from firefighting foams used nearby.
“The biggest point sources (for PFAS) were the firefighting foams, but that it only explained half the total amount was very surprising to us,” said Bridger Ruyle, a Ph.D. student in environmental science and engineering at Harvard University and the lead author of the paper, which was published in the journal “Environmental Science & Technology.”
