ADEL, Iowa (AP) — Iowa officials say a boil advisory has been issued for the city of Adel’s water system. The state Department of Natural Resources says one of Adel’s water towers was being serviced when the city lost electrical service Wednesday morning. This created a pressure loss in the distribution system.

The pressure has been restored, but water must be tested for bacteria before the boil advisory can be lifted. City officials and the DNR recommend that residents boil their water for drinking and cooking. They’re also encouraged to use bottled water.
