Do Not Use water advisory lifted in Aspen Ridge

With the approval of the Water Security Agency and the Saskatchewan Health Authority, the City of Saskatoon has lifted the Do Not Use water advisory for Bolstad Link/Manor/Turn/Way in the neighbourhood of Aspen Ridge. Bolstad residents were taken off the permanent, underground water system and moved to a temporary above-ground system after potential hydrocarbon contamination was discovered in a few area hydrants in January.

“The City commissioned an investigation that led to a thoroughly documented remediation process coupled with many rounds of confirmatory water quality testing,” says Angela Gardiner, Acting General Manager of Transportation and Utilities. “All testing indicates that the water on Bolstad meets or exceeds all regulatory water quality standards.”

The City contracted Stantec, a global engineering firm, to lead the remediation activities in consultation with a senior toxicologist. Inspections and remediation activities included:

  • Camera inspections of hydrant lead pipes and main pipes with a high definition camera to assess conditions before and after remediation.
  • High pressure flushing and regular flushing.
  • Scrubbing, also known as pigging.  

“The watermains and connecting infrastructure have been confirmed to be acceptable or better than typical operating conditions, as a result of extensive remediation,” says Chris Mathies, Principal & Sector Leader with Environmental Services at Stantec. “We will also continue to monitor the water quality and we’re confident it will continue to meet with water quality standards.”

The City’s investigation into the source of the contaminant is ongoing although it has been determined to be an asphalt-type product, of which there are many varieties widely available.

Properties located on Bolstad Link/Manor/Turn/Way received notification that the advisory had been lifted earlier today. The area will be transitioned off of the temporary system and onto the permanent one over the course of the next few weeks.
