Overview
- Baltimore’s Department of Public Works, which announced the change Monday, lowered dosing at the Ashburton and Montebello plants to 0.4 mg/L from 0.7 mg/L.
- Officials said the water remains safe to drink and noted the system serves Baltimore City plus parts of Baltimore and Howard counties.
- DPW attributed the cut to a national shortage of hydrofluorosilicic acid as a key Israeli supplier faces war-related disruptions and U.S. production has declined.
- Parents of young children and others at higher risk were urged to consult dentists about alternative fluoride sources such as topical treatments during the shortfall.
- The move follows WSSC’s April 7 reduction and comes as health groups recommend about 0.5 to 1 mg/L for effective prevention with no federal minimum required.
