The Calgary Fire Department (CFD) is investigating after a substance believed to be mineral oil was spotted on the Bow River, near the Harvie Passage.
In a media statement released Friday morning, Alberta Environment and Parks (AEP) said the oil was released from the outfall at 17 Ave SE and Deerfoot Trail and that it had entered into the western irrigation canal.
The call came in at around 6:20 a.m. on Friday.
As of Friday afternoon, crews had contained the spill
CFD said in a statement on Friday that “further analysis was pending” to determine what the substance is and where it came from.
It added that two booms have been installed on the western irrigation canal, with a third, smaller boom being installed on a storm water outflow on the Bow River.
The CFD reiterated that there is no danger to the public.
In an earlier statement, AEP had said water users downstream of the spill are being notified.
The CFD is also reminding Calgarians that a boating advisory on the Bow River remains in place due to seasonally high flow rates.
