Global Shortage Forces Baltimore to Reduce Water Fluoride
13 Apr
Summary
- Fluoride levels in Baltimore's water system are decreasing due to supply chain issues.
- The reduction is a response to a shortage of hydrofluorosilicic acid.
- Water quality and safety will not be affected by the lower fluoride concentration.

Baltimore's drinking water system is reducing fluoride levels due to ongoing national supply chain disruptions. The city's Department of Public Works (DPW) announced this adjustment, which impacts residents served by the city's water supply, including areas in Baltimore and Howard counties.
The reduction will lower fluoride concentrations from 0.7 to 0.4 milligrams per liter at the Ashburton and Montebello filtration plants. This measure is a direct response to a shortage of hydrofluorosilicic acid, a key component in water fluoridation. Officials cited the war in Iran, decreased national production, and limited international supplier output as contributing factors.
DPW Director Matthew Garbark emphasized that the adjustment is solely due to supply availability, assuring residents that the safety and quality of the water remain unaffected. While fluoride is beneficial for preventing tooth decay, it is not a federally or state-mandated additive. For children at high risk of cavities, dentists can provide alternative fluoride sources during this period.
