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.
Canada, the USA, China and United Kingdom are the largest foreign owners of Australian water. A new report, released by the Australian Tax Office (ATO), will show that foreign ownership of water increased by 0.3 per cent in the year to June 2022. It shows that Canada holds 2.1 per cent of all Australian water entitlements, the USA 1.8 per cent, with China and the United Kingdom each holding 0.8 per cent.
Canada's oil sands mining industry on Thursday outlined proposals to release treated water from tailings ponds into northern Alberta's Athabasca River, a move environmental groups say risks damaging one of the world's largest freshwater deltas. Unlike other extractive industries in Canada, oil sands firms are not allowed to release treated tailings water.
The salinity of freshwater ecosystems caused by road de-icing salts, agriculture fertilizers, mining operations and climate change is increasing worldwide and current water quality guidelines don’t do enough to address the issue, an international study led by Queen’s University and The University of Toledo has found. The research, conducted in collaboration with dozens of scientists across North America and Europe, shows significant damage is being done to freshwater lakes by salt concentrations that are below ranges government regulators have deemed safe and protective of freshwater organisms.
The ten-kilogram rover, measuring 60x60x50cm, will be launched on board the Hakuto lander made by ispace, a lunar robotic exploration company based in Japan. The rover itself, also built by ispace, will have an integrated robotic arm created by the private companies Stardust Technologies (based in Canada) and Australia’s EXPLOR Space Technology. Using cameras and sensors, the arm will collect high-resolution visual and haptic data to be sent back to the mission control centre at the University of Technology Sydney. It will also collect information on the physical and chemical composition of lunar dust, soil and rocks - specifically with a goal of finding water. We know water is present within the Moon’s soil, but we have yet to find a way to extract it for practical use. The big push now is to identify regions on the Moon where water sources are more abundant, and which can deliver more usable water for human consumption, sample processing, mining operations and food growth.
Wastewater from oilsands mining operations have long been a challenge for Canada's energy industry, much of it ending up in industrial tailings ponds. But scientists and engineers at the University of Calgary are taking aim at eliminating watery tailings from the oilsands production process with the help of specialized liquid salt. Hot water is used in oilsands mining operations to extract the oily bitumen from the sand, with the resulting wastewater ending up in tailings ponds to settle and later be reused. Alberta has an estimated 1.3 trillion litres of fluid tailings sitting in tailings ponds.
