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.

Western Engineering investigates freezing technique for water treatment

Western Engineering researchers have teamed up with Core Geoscience Services Inc. (CoreGeo) in a project to investigate the use of cryopurification – water treatment by freezing – for treating contaminated water in a mine in Northern Canada. It is a nature-inspired technology based on physics pointing to ice crystals as essentially made up of pure water. “When contaminated water is gradually frozen, ice crystals of pure water grow while the contaminants are rejected from the crystal structure into the liquid phase. The technology has shown to be effective for the removal of contaminants from aqueous solutions and has the potential to decontaminate water resources to provide a safe and clean water supply,” explained Ajay Ray, professor, department of chemical and biochemical engineering.
