Baltimore Reduces Fluoride Levels in Municipal Water Amid Supply Chain Disruptions

The Baltimore City Department of Public Works (DPW) has announced a temporary reduction in fluoride levels in its municipal water supply, effective this week. The fluoride concentration will decrease from approximately 0.7 milligrams per liter (mg/L) to 0.4 mg/L at the Ashburton and Montebello filtration plants. This decision is attributed to national supply chain disruptions linked to the ongoing conflict in the Middle East, particularly the war in Iran.

Fluoride is commonly added to municipal water systems to help prevent tooth decay, and about 75% of the U.S. population resides in areas with fluoridated water. However, there are no federal mandates requiring fluoride in drinking water; the U.S. Public Health Service recommends a concentration of 0.7 mg/L. The DPW emphasized that the reduction is solely driven by supply availability and does not compromise the safety or quality of the water. DPW Director Matthew Garbark stated, “We remain committed to providing safe, high-quality drinking water.”

The DPW's decision reflects broader national supply chain challenges, which have been exacerbated by geopolitical tensions. Israel, a major exporter of fluorosilicic acid—the additive used for water fluoridation in the U.S.—is directly impacted by these disruptions. The reduction in fluoride levels is a precautionary measure to ensure continued compliance with federal and state water quality standards.

In its statement, the DPW reassured the public that “drinking water will remain safe and meet all federal and state water quality standards.” The agency's commitment to maintaining water quality remains steadfast despite the adjustments. Additionally, Health and Human Services Secretary Robert F. Kennedy Jr. has previously expressed opposition to water fluoridation, indicating a potential shift in public health policy regarding fluoride recommendations.

Opposition to water fluoridation has gained traction, particularly from figures like Robert F. Kennedy Jr., who has indicated intentions to direct the Centers for Disease Control and Prevention to cease recommending fluoride in drinking water. This perspective adds a layer of complexity to the ongoing debate about the safety and necessity of fluoride in municipal water supplies.

While the DPW has clarified the reasons for the fluoride reduction, there is no detailed information on the expected duration of this change or how it may affect public health in the long term. Additionally, the lack of federal requirements for fluoride levels raises questions about the consistency of water fluoridation practices across different municipalities.
