Second update: Parts of Shaw are still under a Do Not Drink advisory, as D.C. Water tests the water for possible contaminants.

DC Water crews worked through the night to flush the water distribution system in the affected area and completed flushing this morning. Samples are being collected and taken for laboratory testing. The goal was to flush the contaminant out of the system by running large volumes of water out of the fire hydrants. If the laboratory tests confirm this was successful, the restrictions could be lifted this afternoon. Those in the affected area should continue to follow the precautions in the advisory below. The source of the contaminant is still under investigation.

DC Water will continue to update as information becomes available. We apologize for this inconvenience, however our primary concern is protecting the health and safety of our customers.

Update: don’t drink tap water if you live here:

Here’s a message fro D.C. Water: If your tap water smells like petroleum, do not drink it.

In addition to not drinking it, report the case to 202-612-3400.
