See the list of sources below for more information on testing. The Vermont Department of Health Laboratory provides chemical, radiological and microbiological tests for public and private drinking water. Our laboratory is accredited by the National Environmental Laboratory Accreditation Program (NELAP) for drinking water testing. We also offer testing for environmental water, such as swim water and irrigation water – see more information on the Environmental Testing page. Water Testing by Source and Business Type Public Water Sources If you pay a bill for your water, or your landlord or housing association pays a bill for your water, your water comes from a public water supply and utility. Under the federal Safe Drinking Water Act, all municipal and other public water supplies must be tested regularly for bacteria, nonorganic chemicals, naturally occurring radioactivity, and naturally occurring compounds. Vermont’s Water Supply Rule includes a list of contaminants and corresponding levels. The Drinking Water and Groundwater Protection Division at the Department of Environmental Conservation oversees the public water testing schedule and compliance. If you have a concern about your public water supply , call the local number listed on your water bill or 800-823-6500 for the Drinking and Groundwater Protection Division of the Agency of Natural Resources.
