A do not use water advisory for roughly one-dozen homes in Saskatoon’s Aspen Ridge neighbourhood was lifted Friday.
In January, people living on Bolstad Link, Manor, Turn and Way were taken off the permanent underground water system after potential hydrocarbon contamination was discovered in a few area hydrants.
The homes have been on a temporary above-ground water system ever since.
“All testing indicates that the water on Bolstad meets or exceeds all regulatory water quality standards,” said Angela Gardiner, the city’s acting general manager of transportation and utilities in a news release.
The city contracted Stantec, a global engineering firm, to lead the remediation activities — such as camera inspections of hydrant pipes, high-pressure flushing and scrubbing. They also consulted with a senior toxicologist.
“The watermains and connecting infrastructure have been confirmed to be acceptable or better than typical operating conditions, as a result of extensive remediation,” said Chris Mathies, with Environmental Services at Stantec, in a news release Friday.
“We will also continue to monitor the water quality and we’re confident it will continue to meet with water quality standards.”
While an investigation into the contamination hasn’t concluded, the city says an asphalt-type product — of which there’s many varieties — has been determined as the source.
The area will be transitioned off the temporary system and onto the permanent one over the course of the next few weeks.
The Water Security Agency and the Saskatchewan Health Authority approved the City of Saskatoon to end the do not use water advisory Friday.
