Drinking Water Fluoridation


Fluoride Level Update

Fort Collins Utilities has confirmed that the Department of Health and Human Services and the Colorado Department of Public Health and Environment (CDPHE) are lowering the recommended amount of fluoride added to drinking water for the first time in more than 50 years (CDPHE press release). Since 1962, the government has been advising water systems to add fluoride to a level of 0.7 parts per million (ppm) for warmer climates, and up to 1.2 parts per million in cooler areas. The new standard is 0.7 ppm everywhere.

Currently, the City of Fort Collins drinking water fluoride levels are in the range of 0.9-1.05 ppm, with the fluoride system monitored continuously. In addition, the ISO140001 certified Water Treatment Facility follows stringent safety procedures when working in and around the fluoride as part of its Environmental Management System. Fort Collins Utilities has been managing fluoridation of our water supply since the 1950s. A re-authorization of fluoridation was performed by public vote in 2005.

Per City Code Sec. 26-50. Fluoridation, the City Council is authorized to fluoridate the water supply system of the City. The utility is directed to fluoridate its water to the levels established by the State Department of Public Health and Environment, now established at 0.7 ppm.

Fort Collins Utilities' next step is to develop an operational plan to lower the fluoride level. An estimated timeline for making the adjustment is mid-May 2015.
