ASHEBORO, N.C. – A malfunction in the fluoride distribution system of the city’s water treatment plant Tuesday morning resulted in an over-release of the chemical into the city’s water supply, according to a news release from the city.

Between 10 a.m. and 11:30 a.m., approximately 60 gallons of fluoride were dispersed into the water system. That same quantity was supposed to be released over a 24-hour period.

According to the city, affected water lines and hydrants were flushed and the fluoride levels in the city’s water system returned to the normal range by 4 p.m.

The over-fluoridation was limited to the area west of U.S. 220 and households in the vicinity of the water treatment plant.

Streets affected include:

Sunset Avenue from Oakhurst to North Ridge, Rolling Road, Crestview Street, Winslow Avenue, West Street, Norman Street, Hamilton Street, Russell Street, North Ridge Street, Rushwood Road, Danwood Street, Old Farmer Road from 220 Bypass to Register Street, Powhatan Avenue from 220 Bypass to South McCrary Street, Lewallen Road from Klaussner Furniture to Old Farmer Road

Residents in the affected areas should let their faucets run two to three minutes before using the water as a precautionary measure.
