DC Water Warns Thousands of Contamination Risk Tens of thousands of people were told to boil their tap water on Friday due possible contamination after an issue at a pumping station.
About 7,000 DC Water customers were under a boil advisory into Sunday after water tested positive for contaminants.
A boil water advisory that affected thousands of people in D.C. Friday and Saturday has been lifted completely, DC Water says.
About 7,000 DC Water customers in Northeast were the last to get the all-clear.
Otherwise, water use can return to normal.
Water taken from pipes servicing those neighborhoods initially tested positive for coliform bacteria.
Further tests confirmed the water was safe leading up to the third day of the boil water advisory, which was initially put into place Friday.
DC Water said it dropped the boil water advisory for all of the other previously affected neighborhoods because all of the tests in those areas came back negative.
Some residents were told their water was safe later on Friday, while many residents of Northwest and Northeast woke up Saturday unable to drink water straight from the tap.
DC Water CEO David Gadis apologized Saturday that the DC Water website went down as residents logged on Friday in search of more information about the boil advisory.
