Fluoride Reporting in Consumer Confidence Reports

Information that must be included in the CCR for systems that fluoridate

Necessary Information in the CCR Contaminant Table

When fluoride appears in the contaminant table, the source of the fluoride must be clearly stated as "Water additive which promotes strong teeth" or similar phrase. Below is an example of contaminant table information:

Contaminant Date(s) Collected Highest Result or Highest Running Average Detected Range Detected MCL MCLG Violation (Y/N) Possible Sources of Contamination
Fluoride 04-23-09 1.1 0.9 - 1.1 4 4 No Water additive which promotes strong teeth


Necessary Information for Treatment Description Section

In the treatment summary area of the CCR the PWS must explain why the treatment was added. Here are some examples of what could be written:

  • Fluoride was added to prevent tooth decay/cavities.
  • Fluoride has been added since (insert year) to prevent tooth decay/cavities.
  • Fluoride addition was passed by referendum vote in (insert year) and added to the water supply in (insert year) to prevent tooth decay and improve dental health.
  • Fluoride is a naturally occurring element in many water supplies in trace amounts. In our system the fluoride level is adjusted to an optimal level averaging one part per million (ppm or mg/l) to improve oral health in children. At this level, it is safe, odorless, colorless, and tasteless. Our water system has been providing this treatment since (insert year). There are over 3.9 million people in 140 Massachusetts water systems and 184 million people in the United States who receive the health and economic benefits of fluoridation.
