Indigenous community hosts full moon ceremony ...

Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.

Potential damage is being downplayed in latest Alberta oil pipeline leak

Potential damage is being downplayed in latest Alberta oil pipeline leak

Less than two months after a spill at an oil pipeline dumped 900,000 litres of contaminated water–so called “produced water”–in northwestern Alberta, there’s been another spill in the oil-rich province. The latest spill, reported at 2 p.m on Christmas Day by a local landowner, occurred near Drayton Valley, a community about 130 kilometres southwest of Edmonton, the province’s capital city. Drayton Valley was the site of a spill–the result of a ruptured pipeline–that dumped 40,000 litres of crude oil into a local creek in August, 2019.

New technique could help decontaminate oilsands process water

New technique could help decontaminate oilsands process water

New technology developed by engineers at the University of Alberta shows potential in cleaning and decontaminating process water from oilsands production. The process relies on ozonation and biofilters to remove organic compounds from contaminated water. The study, published in Science of the Total Environment, demonstrates that the method, previously used to clean pharmaceutical waste water, efficiently removes naphthenic acids, considered to be one of the main contaminants in oilsands process water.
