Fluoride Supply Status
Is Longmont currently supplying fluoride to its drinking water?
Since the 1950s, fluoride has been regularly added to drinking water supplies in the U.S. to prevent tooth decay and reduce the risk of oral disease. Over 74% of the U.S. population on community water systems receives fluoridated drinking water, according to the Centers for Disease Control (CDC). Longmont has been fluoridating its water supply since 1958.
The U.S. Public Health Service currently recommends a fluoride level of 0.7 mg/L in drinking water.
Longmont’s water has a naturally occurring level of about 0.2 mg/L, so a small amount of sodium silicofluoride (SSF) must be added to the water supply to reach the recommend dosage level.
The production and supply chain for sodium silicofluoride (SSF) has changed in recent years leading to delayed delivery cycles and periodic shortages. These recent market changes may occasionally disrupt Longmont’s ability to continuously add SSF to the water supply.
The benefits of fluoridated water come from drinking water over long periods of time. Short-term interruptions (a few days or weeks) will have minimal to no impact on the oral health benefits of Longmont’s water.
Longmont does not have any plans to permanently discontinue fluoridation of its drinking water. Fluoridation will only be discontinued when there are short-term supply disruptions. Longmont City Council has requested that staff use the City’s website to inform residents of the status of Longmont’s fluoridation practice.
