(KELLOGG, Iowa)—A break in a small water main in the 300 block of High Street Tuesday afternoon caused the City of Kellogg to lose water pressure for about an hour.

Loss of pressure can allow bacteria to enter the water distribution system.

The city completed repairs about 8 p.m. Jan. 2, but is advising residents to boil water as a precaution. Bring all water used for drinking, making ice, brushing teeth or preparing food to a boil, let it boil for one minute and let it cool before using. Or, use bottled water. Boiling kills bacteria and other organisms in the water.

Tap water can be used for bathing and similar purposes.

The city will collect and test four sets of water samples, taken 24 hours apart, to determine when the water is safe and the advisory can be lifted.
