Customers in the affected portion of Northwest DC should flush their household or commercial plumbing before using tap water for all purposes.

Responses to frequently asked questions regarding the lifted advisory are available online: https://www.dcwater.com/news/factsheet/pdfs/Dont_Drink_Lift_FAQ.pdf DC Water lifted the DO NOT DRINK advisory after confirming that the drinking water meets Environmental Protection Agency (EPA) drinking water standards. DC Water tested water samples from multiple sites in the affected area after extensive flushing was conducted in the pipe system. IMPORTANT***DC Water and EPA strongly urge you to flush water through your home or building by following the instructions outlined below: Single-Family Homes: • Begin at the sink on the lowest floor and run each cold water tap for 10 minutes. • After 10 minutes, move to upper level sinks and run each cold water tap for 5 minutes. • Flush your refrigerator’s water dispenser for 5 minutes. • Discard any ice that was made during the Do Not Drink advisory. • For automatic ice makers, make and discard one cycle of ice. Commercial and Multifamily Buildings: • Follow same procedure as above AND • Notify all tenants to run every cold water tap for 5 minutes. If you notice a petroleum-type odor after flushing, please notify the Drinking Water Division at 202-612-3440. If you have health concerns, please contact your healthcare provider for advice. Share this information with your friends and neighbors, 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 continues to investigate the cause and source of the contamination. During this event, DC Water worked closely with the Environmental Protection Agency, its partners in the District of Columbia, DC Department of Environment, Washington Aqueduct, and the Metropolitan Washington region to communicate with the public and quickly restore water service. Customers with water quality questions should contact DC Water’s Drinking Water Division at 202-612-3440 (Monday through Friday, 8 a.m. to 4:30 p.m.). All other questions or suggestions should be directed to DC Water Customer Service at 202-354-3600 (Monday through Friday, 8 a.m. to 5 p.m.) or the 24-Hour Command Center at 202-612-3400.
