PFOA found in Bedford drinking water

BEDFORD - Low levels of PFOA contamination have been detected in two Bedford neighborhoods.

According to the New Hampshire Union Leader, new water samples in Cabot Preserve and Greenfield farms revealed perfluorooctanoic acid (PFOA) at 36 parts per trillion.

Pennichuck Water Works, which buys the water supplied to the neighborhoods from the Merrimack Village District, decided to test the water after reports of contamination in Merrimack and Litchfield.

The state Department of Environmental Services began investigating PFOA levels after Saint-Gobain Performance Plastics in Merrimack noticed PFOA in the water at its plant about four weeks ago.

Results from the Merrimack Village Water District, which supplies water to 25,000 residents, showed PFOA levels ranging from 17 to 90 ppt.

PFOA is a man-made chemical, which was once used in Teflon. It has been linked to kidney cancer, testicular cancer and other health issues. There is no regulatory standard for PFOA in drinking water, but the U.S. Environmental Protection agency recommends no more than 400 parts per trillion for short-term exposure.

A public meeting will be held at 6:30 p.m. Wednesday at Peter Woodbury Elementary School, 180 County Road.
