WSSC Water Temporarily Reduces Fluoride Levels in Drinking Water Due to Nationwide Supply Chain Disruptions
Water Remains Safe - No Impact to Quality as a Result of Temporary Change
Written by
Laurel, Md. – April 7, 2026 – WSSC Water is notifying customers today that it is temporarily reducing the level of fluoride added to the drinking water supplied to its 1.9 million customers in Montgomery and Prince George’s counties due to nationwide supply chain challenges linked in part to the ongoing conflict in the Middle East.
WSSC Water will reduce fluoride levels this afternoon from approximately 0.7 milligrams per liter (mg/L) to 0.4 mg/L at its Potomac and Patuxent Water Filtration Plants.
Hydrofluorosilicic acid is the compound used in community water fluoridation. This market has experienced significant disruption in recent months due to reduced domestic production and reduced output from other producers. One major supplier, located in Israel, has experienced significant operational impacts. WSSC Water will continue to receive shipments of the compound, but at a reduced volume.
Fluoride is not mandated by federal or state regulations. Its addition to drinking water is a voluntary public health measure endorsed by leading health organizations, including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), to help strengthen teeth and prevent cavities. The American Dental Association and American Academy of Pediatrics are among other health care advocates who endorse the practice as a tool for optimal oral health.
“This is a temporary adjustment driven solely by supply availability,” said WSSC Water’s Director of Production Ben Thompson. “We remain committed to maintaining safe, high-quality drinking water and will restore optimal fluoride levels as soon as supply conditions stabilize.”
WSSC Water encourages customers to consult with their dentist or healthcare provider about alternative sources of fluoride during this period, especially for children and individuals at higher risk for tooth decay.
