Vermont expanded its drinking water advisory to cover five chemicals and will begin testing drinking water in some schools.
The Vermont Department of Health announced Tuesday it has expanded its drinking water advisory to cover five chemicals known as PFAS. The Department of Environmental Conservation will begin testing the drinking water in 10 schools where cleaning products containing the chemicals have been used.
PFAS were previously used to make Teflon and other nonstick products in addition to other commercial applications. Exposure at high levels is linked to liver damage, developmental problems and some forms of cancer, among other risks.
The chemicals were found in drinking water in Bennington and Pownal in 2016. The chemicals can be removed with a carbon filtration system.
