Update: DC Water announced on Wednesday it has lifted the boil water advisory, saying the drinking water is meeting all standards for water quality safety. Per the agency, water samples tested from multiple sites confirmed there is no risk of contamination from the loss of pressure. Prior to running the water as normal, DC Water is advising residents to do the following:

• Run the cold water taps for 10 minutes (if water was not used at all during the advisory).
• Discard food or ice prepared with water that was not boiled during the advisory.
• Consult the owner’s manual to find out how to sanitize appliances and home filtration systems if used during the advisory.

Original: DC Water is advising customers in a swath of Northeast D.C. to boil their tap water before drinking it or using it for cooking or other household tasks.

The advisory was issued on Sunday evening and is likely to remain in effect until at least Wednesday. It covers the portion of Northeast D.C. between Rhode Island and New York Avenues to the north and south, and from roughly around Brentwood Road NE all the way to the Maryland line at Eastern Avenue. That covers parts of the neighborhoods of Fort Lincoln, Woodridge, and Langdon. The map of the impacted areas is here.

DC Water says it received calls on Sunday evening about low or no water pressure in the area, raising the possibility that bacteria or other organisms could get into water and spread through the area’s distribution system. While the utility says it has no reports that water was actually contaminated, it’s advising customers to take precautions until testing can be completed. On Monday, the utility said it would be testing water at between four and five locations in the impacted area. Two rounds of testing will be needed before the advisory can be lifted.

Anyone who needs to use tap water is asked to heat it to a rolling boil for a minute before cooling. If water is discolored, customers are asked to let it flow until it runs clear, and then boil it. Any ice that was made using existing water should be discarded.

DC Water users with any water quality questions can call (202) 612-3440, and any other questions can be directed to the utility at (202) 354-3600 during normal business hours and 202-612-3400 after those hours.
