Early this morning, Friday, November 8, 2019, a water main break in Arlington, Virginia caused a loss of pressure in the distribution system in upper Northwest DC, west of Rock Creek Park. Both the District and Arlington County, Virginia receive water from the Dalecarlia Water Treatment Plant. Arlington responded to the break and pressure was restored. The lack of pressure made it possible for bacteria or other disease-causing organisms to enter the water through cracks, breaks or joints in the distribution system.
Bacteria and other disease-causing contamination such as viruses and parasites can cause symptoms such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly and people with severely compromised immune systems.
The symptoms above are not caused only by microbes in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice about drinking water from their health care providers.
We have no information that the water was contaminated by this incident, but issue this advisory as a precaution while we test the water. Our Water Quality staff are sampling and testing the water and crews are flushing the distribution system with clean water to get rid of potentially contaminated water in the distribution system. We anticipate receiving the sampling test results from the laboratory by the afternoon of November 9.
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 notice in a public place or distributing copies by hand or mail.
