Drinking Water Warning Cancelled In Waterloo

Drinking water is safe to consume for all residents in Waterloo, including infants. City officials have cancelled the warning they issued on Friday (Nov. 6, 2015).

Late last week, the Waterloo Water Works issued a public notification that the nitrate level in the water produced by Well No. 22 at 604 East Dale Street was found to have a nitrate level of 10.7 mg/l, 0.7 mg/l above the maximum allowable nitrate level of 10 mg/l. At that time, city officials warned that the above-standard contaminant level posed a serious health concern for infants and they advised residents not to give the water to children under six-months-old or use it to make formula.

The test results for Well No. 22 spiked on Friday, causing the public notification. Waterloo Water Works officials said the Dale Street well was shut down immediately after tests showed the nitrate levels were too high.

According to city officials, the well will remain shut down until nitrate levels in the water produced there fall below the acceptable 10 mg/l level.

Water produced by all other wells in the Waterloo Water Works system has nitrate levels well below the maximum limit, city officials said. Therefore, they've lifted the drinking water warning.

According to city officials, drinking water produced by the Waterloo Water Works is once agains safe for all residents to drink, including infants.
