UPDATE: The Port Washington Boil Water advisory has been lifted

------

PORT WASHINGTON, Wis. (CBS 58) -- A boil advisory in Port Washington has been extended until 7:30 p.m. on Thursday, November 16. 

On Wednesday, the city had a complete loss of water pressure in an area west of South Park Street and south of West Grand Avenue after a car hit a fire hydrant.

Wisconsin DNR requires communities to collect at least five water samples after a water pressure loss and does not recommend drinking the water until the samples say it is safe to use. The water should be okay for washing and flushing, but not drinking.

Any water that is used for cooking or drinking should be bottled or boiled for at least one minute. 

The water tests take at least 24 hours and the city of Port Washington hopes to have results by Thursday evening.
