Three Twin Cities suburbs remain under boil water advisory

A boil water advisory for residents of New Hope, Crystal and Golden Valley remained in effect Monday following a temporary drop in water pressure on Sunday, officials said.

“While there’s no confirmed contamination, cities are following state health guidelines to make sure the water is completely safe,” according to a news release.

Test results were pending as of Monday morning. A statement from the City of Crystal said it takes 16 to 18 hours for results to come back and the advisory would remain in place for 24 hours.

The advisory was issued after a valve on a water tower in Golden Valley malfunctioned overnight from Saturday night to Sunday, New Hope reported on social media Sunday morning.

Crews were working to restore water to the cities. New Hope reported shortly after that staff had restored water pressure.

The Department of Health was testing the water, and a New Hope spokeswoman estimated the boil advisory would remain in effect for 24 hours.

New Hope Mayor John Elder wrote on Facebook that the water tower valve inadvertently closed Saturday night.

Residents were advised to use bottled water or boil tap water for drinking, washing dishes, cooking and brushing their teeth unless they have been notified that temporary water hookups have been successful.

Officials recommend boiling the water for at least 1 minute and letting it cool before using it.

City staff will notify residents when the advisory has been lifted. At that point, authorities suggest people flush their building plumbing systems.
