Do Not Use water advisory lifted in Rosewood
With the approval of the Water Security Agency, the City of Saskatoon has lifted the Do Not Use water advisory for the Rosewood Commercial Area, including Meadows Market. The area has been under an advisory since May 11, 2018 after potential hydrocarbon contamination was discovered in a few area hydrants.
“This type of contaminant was something we had no experience with so we needed time to conduct comprehensive testing and formulate a careful approach to remediation,” says Angela Gardiner, Acting General Manager of Transportation & Utilities. “The process to lift the water advisory wasn’t a quick one but it was thorough which means we can feel confident in lifting the advisory and returning the area to full use of the permanent underground water supply.”
“Initially, all that was understood was that a black substance was identified in certain hydrants that potentially contained hydrocarbon properties,” says Chris Mathies, Principal & Sector Leader with Environmental Services at Stantec—a global engineering firm contracted to lead remediation. “We now know that the water quality in the Rosewood Commercial Area was not compromised. As a precautionary measure, remediation activities were carried out to thoroughly clean and test the water infrastructure.”
Inspections and remediation activities conducted in June-July 2018 included:
• Camera inspections of water distribution system with a high definition camera to assess conditions before and after remediation.
• High pressure flushing and regular flushing.
• Scrubbing, also known as pigging.
Since the completion of inspection and remediation activities, confirmatory testing has been ongoing to verify that the water continues to meet all drinking water standards. Properties located within the Rosewood Commercial Area, including Meadows Market, received notification that the advisory had been lifted earlier today.
