Alberta plans water standards as oilsands wastewater grows
Canada is fast-tracking a West Coast oil export pipeline, adding urgency to a decision about wastewater from oilsands mining in Northern Alberta.
For about 60 years, the industry has been barred from releasing water, leaving large ponds filled with toxic mining wastewater.
The volume of tailings fluid grew by 50 per cent from 2014 to 2024, and the total is equivalent to 600,000 Olympic-sized swimming pools.
Alberta plans to set water quality standards by year-end, while Ottawa will decide whether to adopt them, change them or keep the ban.
Companies say they can treat the water and need rules to guide them, while some Indigenous leaders want production slowed until the issue is resolved.
The Alberta government wants crude production to double, and officials say the ponds are at capacity and more storage lakes are not wanted.
Federal rules will determine whether treated water can be released, as the ponds continue to fill.
Alberta plans to set water-quality standards by the end of the year for releasing treated oilsands wastewater.
The wastewater is held in tailings ponds in Northern Alberta, where the industry has been prohibited from releasing water.
The volume of tailings fluid grew by 50 per cent from 2014 to 2024, according to the Alberta Energy Regulator.
Oilsands companies say they need regulations to treat and release the water, while some Indigenous leaders want production to slow until the issue is resolved.
The proposed standards would require Ottawa’s approval because the waterways fall under federal jurisdiction.

What people are saying
The solution isn't just to keep doing nothing and put our head in the sand. The solution is to actually prove out the science.
We cannot say to industry, 'we want you to double production,' and then not give them the tools to be able to do proper treat-and-release.
Treating and release is really critical to enabling the large-scale reclamation of these facilities,
These tailings facilities are not meant to be permanent parts of the landscape in the region.
