DC Water is advising thousands of residents in Northwest and Northeast D.C. to boil their tap water before drinking it or cooking with it.
A map the water authority released early Friday shows that a major portion of the city is affected, starting north of K Street and New York Avenue and running the entire width of the District from east to west.

The “boil water advisory” is in effect until futher notice and is a precaution after a problem with the water system Thursday night.
Also, DC Water is advising people to boil their water if they had no water or low water pressure after 8:30 p.m. Thursday.
D.C. Deputy Mayor Kevin Donahue warned residents of the problem, and the city issued an alert through its AlertDC system.
The problem began because a valve was open about 8:30 p.m. Thursday at the Bryant Street Pumping Station. That resulted in a loss of pressure that can allow contaminants to enter the water. The cause of the problem was not immediately known.
