Understanding Vermont's Well Water Regulations
Testing Frequency
Vermont requires well water testing at property sale. This means that when a home with a private well is sold, the seller (or in some cases the buyer) must obtain water test results from a certified laboratory. The results must be provided to the buyer before closing. Beyond the sale requirement, regular testing is recommended but not mandated by the state.
New Well Requirements
Vermont requires testing when a new well is constructed or an existing well is significantly modified. The required tests include bacteria (coliform/e. coli), nitrate, nitrite, and the well must pass these tests before being put into service for drinking water. Well construction must comply with state standards and a permit is required before drilling.
State Laboratory and Testing Resources
Vermont operates a state laboratory or participates in a state lab network that provides water testing services, often at subsidized rates below commercial laboratory prices. Contact your state health department or environmental agency for current pricing and sample submission procedures. Many county health departments also offer basic bacteria testing, sometimes at no cost. The average cost for a comprehensive well water test in Vermont is approximately $350, though a basic bacteria and nitrate screen may cost significantly less.
