DC Water is working to refine the impacted area. DC Water advises customers located in the current affected area to continue boiling water for drinking and cooking until further notice. Customers in the affected area should also boil their water if they experienced low water pressure or had no water after 8:30 p.m. on July 12. Customers should visit the interactive map at dcwater.com or call the 24-Hour Command Center at (202) 612-3400 to verity if their street address is in the affected area. If customers are not located in this area, they do not need to boil their water.

Customers affected by the boil water advisory should follow these precautions:

• If water is discolored, run the tap until clear, prior to boiling.
• Bring water to a rolling boil for 3 minutes.
• Allow water to cool before using.
• Store cooled water in a clean container with a cover.

Customers should use cooled, boiled water or bottled water for:

• Drinking
• Brushing teeth
• Preparing and cooking food
• Making ice (discard beverages and ice that were made prior to boil water advisory)
• Preparing infant formula
• Giving water to pets

*Do not use home filtering devices in place of boiled or bottled water

On July 14, DC Water received one positive test result out of the multiple sites tested throughout the affected area that indicated the presence of contamination. DC Water is working closely with the Environmental Protection Agency (EPA) to notify the public and take steps to remove any contamination. To correct the problem, DC Water will continue flushing water from the system, and testing water samples to assess water safety.

We will be able to narrow down the affected area later today, once we have determined the precise boundaries. The safety and health of our customers are our top priorities, and the boil water advisory will remain in effect until we confirm that the water is safe.

On July 12, an open valve at Bryant Street Pumping Station resulted in a loss of pressure in portions of our distribution system for about an hour. The loss of pressure in the pipe system made it possible for contaminants to enter the water.

Some populations may be at greater risk for adverse health effects. If you are in this more sensitive group, please consult your medical provider for advice. Symptoms associated with exposure to contamination include nausea, vomiting, and gastrointestinal distress. If you experience any of these symptoms, please contact your medical provider.

Please share this information with everyone in the affected area, 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 notice in a public place or distributing copies by hand or mail. DC Water will provide the next update later today.
