Swea City in Kossuth County, Iowa issued a boil advisory early Tuesday, after a plan for routine cleaning of the water tower was disrupted.
Because of a pump malfunction, there was the potential for a drop in water pressure, which could possibly allow bacteria to enter the drinking water.
As a precaution, the city and DNR recommend residents boil water used for drinking and cooking, or use bottled water until test results for bacteria come back clean.
Residents should bring water to a boil, boil it for one minute and let it cool before using it for drinking, making ice, brushing teeth and preparing food. Tap water can be used for bathing and similar uses.
Boiling kills bacteria and other organisms. Bacteria in the water may pose greater health risks for infants, young children, some of the elderly and people with compromised immune systems.
The city or DNR will notify residents when the water is safe to drink.
