BURLINGTON, Vt. — Vermont environmental officials they’ve discovered high-than-allowed levels of a chemical in three drinking water systems. But testing so far does not point to widespread problems in Vermont drinking water.

Officials say the compounds collectively known as PFAS were found in drinking water at Fiddlehead Condominiums in Fayston, and at Killington Mountain School and Mount Holly School.

Officials urge people in those areas to drink bottled water.

The Department of Environmental Conservation has received 65 percent of the state’s data on public drinking water systems, WCAX-TV reports. Officials say the testing facility is backed up.

Ellen Parr Doering, of the agency’s drinking water and groundwater protection division, said the data will speak for itself. But she said testing so far points toward a relatively small number of contaminated sites.

PFAS compounds are increasingly turning up in public water supplies and private wells around the country. They are used in firefighting foam, nonstick pots and pans, water-repellent clothing, and many other household and personal items.
