Oil that leaked from a Jefferson Parish business made its way into the 17th Street Canal on Tuesday before being contained by the New Orleans Sewerage & Water Board and the Jefferson Parish Environmental Affairs Department.

The canal runs between the two parishes.

The oil, which resulted in a sheen on the water close to the canal’s pump stations near Lake Pontchartrain, was contained near the mouth of the canal, according to a news release from the S&WB. Crews from both parishes were working to clean up the spill Tuesday.

The oil is believed to have come from a spill at Delta Petroleum in Jefferson Parish on Sunday, according to the water board.

The spill did not affect the pumps’ operations, officials said.
