West Allis residents will soon be drinking water with less added fluoride, but city officials say the change does not signal a broader water-quality problem. Milwaukee Water Works plans to reduce fluoride levels temporarily while it searches for a new supplier.
West Allis gets its drinking water from Milwaukee Water Works, according to the city’s water-quality page. The utility’s fluoride reduction is scheduled to begin Friday and remain in place until a new supplier is secured later this year.
What West Allis Residents Need To Know
The change affects fluoride levels only, according to the City of West Allis update. The city says its drinking water remains safe and continues to meet state and federal water-quality standards, while most residents do not need to change their usual oral-health routines.
Milwaukee’s fluoride information says the utility normally adds fluoride to treated drinking water at a level no higher than 0.7 milligrams per liter. The Centers for Disease Control and Prevention says 0.7 mg/L is the recommended concentration intended to maximize fluoride’s oral-health benefits while minimizing potential harms.
Why Milwaukee Is Looking For Another Fluoride Supplier
The supplier hunt is also visible in Milwaukee’s public procurement records. A city procurement notice sought a vendor contract for hydrofluorosilicic acid, the chemical used in water fluoridation, with bids due Monday.
That procurement record does not explain the West Allis announcement by itself, but it suggests Milwaukee Water Works is actively working through its fluoride-chemical supply arrangements. Similar utilities have cited broader market disruptions: WSSC Water in Maryland announced a temporary reduction in April, and the Associated Press reported that other U.S. systems were also affected.
For households with specific dental or health concerns, West Allis officials recommend speaking with a care provider. Otherwise, the city says the temporary change does not require a new household water routine, with further updates expected as Milwaukee secures a supplier later this year.
