A boil water advisory was in effect for a limited area of the city after a loss of pressure at a pump station was caused by a power outage, city officials said.

SALEM, Ore. — A water boil advisory that was in place for part of South Salem was lifted Monday morning after bacterial tests came back clean.

Residents were advised to boil their water before using it following a power outage that caused a temporary loss of water pressure at a pump station on Saturday night, according to the city of Salem.

A Portland General Electric power outage in the S4 water pressure zone caused a safety device at the Davis Road Water Pump Station to shut down the pumps around 7 p.m. on Saturday, city officials said.

The city warned that potentially harmful bacteria could be present in the water supply. The bacteria could cause illness and is a particular concern for people with weakened immune systems.

City officials confirmed that the advisory was lifted Monday morning.

As a precaution, residents in the affected area were advised to bring water to a rolling boil for one full minute, allow the water to cool before using and store the cooled water in a clean container with a cover, the city said. Customers should use boiled or bottled water for drinking, brushing teeth, washing fruits and vegetables, preparing food and baby formula, making ice and cleaning food contact surfaces.


City crews will flush water mains in the affected area and collect bacteriological samples. Results came back early Monday, and residents will be notified when tests show that bacteria are no longer present and water no longer needs to be boiled.
