The City of Arlington has issued a drinking water warning after tests showed nitrate levels above the federal safety limit. Officials are urging residents not to give tap water to infants under six months old or to use it for making infant formula.
A water sample collected on Oct. 8 showed a nitrate level of 11 milligrams per liter (mg/L), exceeding the federal maximum contaminant level of 10 mg/L. Nitrate in drinking water is a serious health concern for infants younger than six months, as it can cause “blue baby syndrome,” a potentially fatal condition marked by shortness of breath and bluish skin.
Safety Recommendations
Do not give the water to infants under six months old. Bottled or low-nitrate water should be used for drinking, juice, and formula preparation until further notice.
Do not boil the water. Boiling or freezing does not reduce nitrate levels and may increase concentration as water evaporates.
Adults and children older than six months may safely drink the tap water. Pregnant women and those with health concerns should consult their doctor.
Cause and Next Steps
City officials said the elevated nitrate levels likely resulted from natural, industrial, or agricultural sources, including septic systems and runoff. Nitrate levels can fluctuate during the year, and the city will notify residents when concentrations return to safe levels.
In the meantime, bottled water is being provided for infants up to six months old, pregnant and nursing mothers, and elderly residents with health conditions. Bottled water can be picked up at the City Office in Arlington.
