For purposes of this report, a water system is considered a community water system if so designated by the state drinking water administrator in accordance with the regulatory requirements of the US Environmental Protection Agency. In general, public water systems provide water for human consumption through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. A community water system is a public water system that supplies water to the same population yearround.

2012United StatesUSWater FluoridationNumber of CWS with naturally occurring fluoride at or above optimal levelsWFRSCount6151.00b,eb: Reported in CDC Water Fluoridation Reporting System (WFRS). For purposes of this report, a water system is considered a community water system if so designated by the state drinking water administrator in accordance with the regulatory requirements of the US Environmental Protection Agency. In general, public water systems provide water for human consumption through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. A community water system is a public water system that supplies water to the same population yearround. Available at http://water.epa.gov/infrastructure/drinkingwater/pws/factoids.cfm. e: The increase from 2010 to 2012 in the population served by CWS with naturally occurring fluoride at or above optimal levels is due in part to two changes: 1) several states have improved the completeness and accuracy of their data for the natural fluoride concentration of community water systems and 2) some states had implemented the proposed recommendation of 0.7mg/L as the optimal concentration of fluoride in drinking water by December 31, 2012.

In general, public water systems provide water for human consumption through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. A community water system is a public water system that supplies water to the same population yearround. Available at http://water.epa.gov/infrastructure/drinkingwater/pws/factoids.cfm. e: The increase from 2010 to 2012 in the population served by CWS with naturally occurring fluoride at or above optimal levels is due in part to two changes: 1) several states have improved the completeness and accuracy of their data for the natural fluoride concentration of community water systems and 2) some states had implemented the proposed recommendation of 0.7mg/L as the optimal concentration of fluoride in drinking water by December 31, 2012.

For purposes of this report, a water system is considered a community water system if so designated by the state drinking water administrator in accordance with the regulatory requirements of the U.S. Environmental Protection Agency. In general, public water systems provide water for human consumption through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. A community water system is a public water system that supplies water to the same population yearround. Available athttp://water.epa.gov/infrastructure/drinkingwater/pws/factoids.cfm. e: The increase from 2012 to 2014 in the population served by naturally fluoridated water systems at or above optimal levels likely resulted from inclusion, for the first time, of the number of persons served by these systems in California as reported in WFRS. The total number of persons receiving fluoridated water in California was based solely on state data and may not fully reflect this increase derived from WFRS data.WFRS_Nat_11US11011914156

For purposes of this report, a water system is considered a community water system if so designated by the state drinking water administrator in accordance with the regulatory requirements of the US Environmental Protection Agency. In general, public water systems provide water for human consumption through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. A community water system is a public water system that supplies water to the same population yearround.
