Public Water Systems conducting water quality monitoring for constituents under the Safe Drinking Water Act State and State of Vermont Water Supply Rule, Chapter 21, are required to have all samples analyzed by a laboratory certified for drinking water analyses by the Vermont Department of Health. The certifying authority in Vermont for both in-state and out-of-state laboratories is the Vermont Department of Health - List of Certified Labs. Laboratories are required to be certified for all contaminants in a group before they will receive an "X" for that group as listed on the Vermont Department of Health, Laboratories Certified for Drinking Water Analysis table.
