What is Vermont’s drinking water standard?
Alpha radiation is measured in picocuries per liter (pCi/L). If alpha radiation is detected at or above 5 pCi/L in your home well, additional testing is needed to pinpoint the source. The U.S. Environmental Protection Agency has set 15 pCi/L as the maximum contaminant level for public drinking water supplies. This level is calculated as the total alpha radiation minus uranium and radon. For more information, contact the Department of Environmental Conservation, Water Supply Division.
