Maryland Utility Reduces Fluoride Levels Due to Middle East Supply Chain Disruptions
WSSC Water, the utility serving Montgomery and Prince George's counties in Maryland, has temporarily reduced fluoride levels in its drinking water due to supply chain challenges linked to the conflict in Iran. The reduction affects 1.9 million customers, with fluoride levels lowered from 0.7 to 0.4 milligrams per liter. The change is attributed to operational impacts faced by an Israeli supplier of hydrofluorosilicic acid, a compound used in water fluoridation. Despite the reduction, the water remains safe to drink, according to WSSC Water. Fluoride is added to public water supplies to prevent tooth decay, supported by the CDC and the American Dental Association. The utility encourages customers to consult their dentists about alternative fluoride sources, especially for those at higher risk of tooth decay.
