WASHINGTON (DC News Now) — The District of Columbia Water and Sewer Authority (DC Water) issued a Boil Water Advisory after customers in part of the District reported that they lost water pressure Sunday.

The reason for the advisory is that when there’s a loss of pressure in the water supply system, it’s possible for bacteria or other disease-causing organisms to enter the water through cracks, breaks or joints in the distribution system.

DC Water said the advisory covered the neighborhoods of Fort Lincoln, Woodridge, and Langdon. It added that the impacted area generally was:

  • East of Montana Avenue
  • West of Eastern Avenue
  • South of Rhode Island Avenue
  • North of New York Avenue

In the neighborhoods affected, DC Water said people should not drink or cook with their water without boiling it first.

If you’re not sure if you’re in the affected area, you can check your address on an interactive map or call the 24-Hour Command Center at (202) 612-3400.

DC Water said customers in the impacted area should:

  • Discard any beverages and ice made before and during this advisory.
  • Run cold water until clear (if discolored) prior to boiling.
  • Run cold water for 2 minutes if known sources of lead are present prior to boiling.
  • Bring water to a rolling boil for 1 minute and let it cool.
  • Store cooled water in a clean, covered container.

Cooled, boiled water or bottled water should be used for:

  • Drinking
  • Brushing teeth
  • Preparing and cooking food
  • Washing fruits and vegetables
  • Preparing infant formula
  • Making ice
  • Giving water to pets

One note: DC Water said you should not use home filtering devices in place of boiled or bottled water.

There was no indication that the drop or loss of pressure led to contamination. DC Water said the advisory was put out as a precaution while it tested the water. It added that the advisory would be lifted when tests on two consecutive days showed no bacteria present.

Although DC Water initially expected customers would be able to resume normal water use on Tuesday, it provided an update to say it anticipated people could start using water as usual on Wednesday May 31, as long as the advisory was lifted by then.
