The boil-water advisory in effect for 50,000 Poway residents was lifted by state authorities late Friday afternoon.

“Effective immediately, the precautionary boil water advisory has been lifted,” the city announced at 6 p.m. “Poway water customers can use tap water for all purposes.”

The advisory went into effect last Saturday afternoon after a day of reports of discolored water. Residents were advised to boil water for at least a minute, while restaurants and produce shelves were ordered closed.

The problem was traced to rain runoff contamination of the “clearwell,” a large reservoir at the city’s water treatment plant.

“The City of Poway Water System, in conjunction with the State Water Resources Control Board, has determined that, through abatement of the health hazard and comprehensive testing of the water, your water is safe to drink,” the city said.

Residents were advised to flush their internal plumbing, throw out ice, and replace filters, with a complete list or recommendations available online.
