WASHINGTON (WUSA9) -- The National Park Service lifted the advisory Monday discouraging recreational use of the water in the Chesapeake and Ohio Canal.
NPS said the water quality tests show that the water is well within the Environmental Protection Agency's water quality standards.
Authorities said the advisory was put into place below Lock 7 in the C&O Canal because of a combined sewage overflow that happened during a storm from DC Water and WSSC sewage lines.
The NPS said that there will be another round of testing sometime later this week. The test will confirm that bacterial levels have dropped further or stabilized at typical levels.
Cleanups along the canal and the Capital Crescent Trail are done. The trail opened up again on Friday, according to the NPS.
