ONAWA— Officials with the Iowa DNR, late Sunday, said the boil advisory for Onawa that was issued on June 25 has been lifted. Two consecutive sets of water samples have been completed and show no bacteria present. Residents can now use the water without boiling.

A malfunctioning sensor drained the city of Onawa’s water storage structure overnight Thursday. Water pressure was restored, but can cause bacteria to enter the water distribution system. As a precaution, the city and DNR recommended residents boil their water.
