A "do not drink" advisory has been lifted for portions of D.C.'s Shaw and Logan Circle neighborhoods two days after it was issued.
Officials had detected petroleum in tap water; crews "flushed" out the system Thursday and Friday.
Someone first reported a foul odor in the water at Cleveland Elementary School on 8th Street NW Wednesday afternoon. D.C. Water officials went door to door, distributing water to residents affected by the "do not drink" advisory.
A "petroleum or tar-like" substance was detected in the water Wednesday, and officials confirmed Thursday it was, in fact, petroleum. As of Thursday evening, they said they did not know how or why the substance got into the water.
The advisory was lifted Friday afternoon.
Three D.C. Public Schools elementary schools -- Cleveland, Garrison and Seaton -- were closed Thursday and Friday due to the advisory.
During the advisory, residents were told they could use the water to flush toilets, wash clothes or water plants. According to D.C. Water officials, skin or eye irritations could occur if the water was used for washing.
The area affected was bordered by:
- South: Q Street NW and Rhode Island Avenue NW
- East: 8th Street NW
- West: 13th Street NW
- North: S Street NW between 9th and 13th streets, and T Street NW between 7th and 9th streets
