The Department of Natural Resources has advised residents of the central Iowa city of State Center to boil their drinking water due to a water main break. The DNR says the water line broke Sunday afternoon, and while the problem was being repaired the system lost water pressure. That can allow bacteria to enter the system, prompting the request that residents boil water used for drinking or cooking.
The advisory will remain until two sets of bacteria samples show the water is safe. The first set of samples will be taken Monday. State Center residents should bring water to a boil and then let it boil for a minute before cooling and drinking it. They also can use bottled water. Boiling water kills bacteria and other organisms.
