This list is derived from an Excel file posted on the Montana Department of Environmental Quality website, 2020. Here we list only municipalities and other water systems with at least 400 customers. The list does not specify if the source of fluoride is natural or artificial. Cities and towns with at least 0.7 mg/L fluoride are listed as fluoridated. Concentrations greater than 1.0 mg/L are indicated in parentheses. Many of the measurements were made five to ten years ago.
