Temporary Reduction of Fluoride Levels in Maryland Drinking Water Due to Supply Chain Issues
4/9/2026, 3:05:22 AM
Overview of the Situation
WSSC Water, serving nearly 2 million customers in Montgomery and Prince George's counties, has announced a temporary reduction in fluoride levels in drinking water from 0.7 milligrams per liter (mg/L) to 0.4 mg/L. This decision is attributed to supply chain disruptions linked to the ongoing conflict in the Middle East, particularly affecting a major supplier of hydrofluorosilicic acid based in Israel.
Impact on Public Health
Fluoride is widely recognized for its dental health benefits, endorsed by organizations such as the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO). The reduction in fluoride levels is significant, as it may impact the effectiveness of cavity prevention efforts in the community. Dr. Charles Doring, president of the Maryland State Dental Association, noted that community water fluoridation has historically reduced decay rates by approximately 30%.
WSSC Water has assured customers that the drinking water remains safe and that this adjustment is solely due to supply availability. Ben Thompson, WSSC Water’s Director of Production, emphasized the commitment to restoring optimal fluoride levels as soon as conditions stabilize.
Supply Chain Challenges
The supply chain issues stem from operational impacts on a key supplier in Israel, which has faced significant disruptions due to the conflict. WSSC Water will continue to receive shipments of hydrofluorosilicic acid, but at a reduced volume. The utility has stated that while fluoride addition is not mandated by federal or state regulations, it is a voluntary public health measure that many utilities adopt to enhance dental health.
Recommendations for Residents
In light of the temporary reduction, WSSC Water encourages residents, particularly those with children or individuals at higher risk for cavities, to consult with their dentists regarding alternative fluoride sources. Options may include prescription fluoride products or specialized toothpaste. Dr. Dennis O’Leary from DDS Family & Cosmetic Dentistry suggested that patients could explore topical fluoride treatments during this period.
Official Statements
WSSC Water has reiterated its commitment to maintaining high-quality drinking water and has communicated that the reduction is a temporary measure. “This is a temporary adjustment driven solely by supply availability,” stated Ben Thompson. “We remain committed to maintaining safe, high-quality drinking water and will restore optimal fluoride levels as soon as supply conditions stabilize.”
What's Next
While WSSC Water has not provided a specific timeline for when fluoride levels will return to normal, the situation remains under close observation. The utility will continue to monitor supply chain developments and update the public as necessary.
