Fluoride

Water Fluoridation

The federal Department of Health and Human Services proposes changes to community fluoridation levels.

On January 7, 2011, the federal Department of Health and Human Services (HHS) and the Environmental Protection Agency (EPA) issued a joint statement regarding fluoride. HHS proposed that the recommended level of fluoride in drinking water can be set at the lowest end (0.7 mg/l) of the current optimal range (0.7 to 1.2 mg/l) to prevent tooth decay.

HHS’ proposed recommendation of 0.7 mg/l is based on recent EPA and HHS scientific assessments to balance the benefits of preventing tooth decay while limiting any unwanted health effects.

Maine CDC will begin the rule-making process to formally incorporate this new dose level. We anticipate the rulemaking process will take approximately 3 to 4 months. In the meantime it is reasonable for all public water systems to adopt the new federal recommendation.

In 2009 the percentage of Maine people on public water supplies who have fluoridated water is about 84%. About 49% of Maine people use public water supplies. This means that overall about 37% of Maine’s total population has fluoridated drinking water in their homes.

Fluoride Test Kit

All well water should be tested by a certified water laboratory to find out how much fluoride is in the water naturally. You can download an order form and order a test kit for fluoride from the Department (Microsoft Word*)(*free viewer) or contact another certified water lab of your choice.


As of February 29, 2012, the Rules Relating to Fluoridation of Public Water Systems were incorporated into 10-144 CMR, Chapter 231, the Rules Relating to Drinking Water
