They say that the test detected total coliform (bacteria) in the smaller affected area. DC Water says E. coli was not found in the areas tested.
DC Water says customers residing in previously impacted areas no longer under the boil water advisory should run cold water taps for 10 minutes before returning to normal water usage.

Turkey Thicket Pool remains closed.
All hospitals within the affected area have back up water plans.
There was some scrutiny on the water provider from customers, after residents say they were not informed of the advisory in a prompt manner, and many had issues reaching DC Water after the high-volume of calls and website traffic.
DC Water says they say they will share further updates as they come.
DC Water reports 40 homes are impacted by an emergency water outage on I (Eye) Street NE between 12th and 13th Street NE for 8-10 hours due to water services repair. It is not known if the outage is due to the boil water alert.
