Global Conflict Halts US Water Fluoride Supply

U.S. public water systems are experiencing an unprecedented shortage of hydrofluorosilicic acid, a key chemical used to fluoridate drinking water and prevent cavities. Supply chain disruptions, exacerbated by the conflict in the Middle East, have significantly impacted the availability of this crucial substance, which is primarily sourced from international producers.

Baltimore and the surrounding Maryland suburbs served by WSSC Water have already reduced their fluoride levels from the recommended 0.7 mg/L to 0.4 mg/L. This decision was prompted by alerts from suppliers about reduced deliveries. These utilities are rationing their chemical usage to stretch existing supplies, a move not seen before even during global disruptions like the COVID-19 pandemic.

The shortage is partly attributed to the call-up of factory employees into military service in Israel, a major producer of the chemical. While some smaller municipalities have seen supply issues temporarily resolved, water managers express concern that a prolonged conflict could force a growing number of systems to halt or reduce fluoridation treatments, affecting the approximately 60% of the U.S. population that receives fluoridated water.
