UPDATE: DC Water Lifts Boil Water Advisory for All Affected Customers – Effective 7:30 AM July 4, 2024

July 04, 2024

All DC Water customers under the precautionary boil water advisory can use tap water for all purposes after it was confirmed that drinking water provided by the Washington Aqueduct never deviated from U.S. EPA established water quality standards as had been anticipated.

Under advice from the Washington Aqueduct, DC Water issued the precautionary boil water advisory as a conservative measure to protect public health, and we sincerely appreciate our customers’ patience while we took necessary precautions to ensure the safety of the tap water we deliver.

The advisory affected all customers in the District of Columbia, as well as the Pentagon, Arlington National Cemetery and Reagan National Airport. Arlington County customers were also impacted.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this public notice in a public place or distributing copies by hand or mail.

DC Water will work with customers to answer questions and respond to additional issues following the Boil Water Advisory. Questions can be directed to DC Water Customer Service at 202-354-3600 (Monday through Friday, 8:00 a.m. to 5:00 p.m.) or the 24-Hour Command Center at 202-612-3400. Information is also available at dcwater.com and Bilingual FAQs are provided at www.dcwater.com/boilwaterFAQ.
