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.
With government agencies dealing with the urgent public safety needs of the day, the health of fish habitat ranked low on the list of priorities. But as floodwaters rose, the distinction between terrestrial and aquatic habitats blurred, salmon and sturgeon swam across farmers’ fields, and contaminants from human activities washed unfettered into streams and rivers.
People who live and play along the Gatineau River between Chelsea and Low, Que., say they've been left high and dry after Hydro-Québec lowered water levels. The change was needed to work on the hydroelectric dam in Chelsea — with rocks now emerging from the river like miniature islands. Heather Horak relies on the river for her seasonal home's water and hauls essential supplies using a pontoon boat.
It’s easy enough to shrug it off when a research paper that involved the study of nearly 400 temperate lakes worldwide identified Wascana Lake as among the leaders in water bodies that are losing oxygen the fastest, both at the surface level and at the lake bottom. While many people might regard the Regina lake as nothing more than a glorified slough unworthy of global consideration, the factors that contribute to its degradation also affect lakes elsewhere in Saskatchewan — particularly the shallow lakes across the southern part of the province — and indeed across much of Canada.
QUÉBEC, Jan. 15 2020 /CNW Telbec/ - Atrazine is one of the most widely used pesticides in North America. Researchers at the Institut National de la Recherche Scientifique (INRS) have developed a new method to degrade it that combines a new nanostructured material and sunlight. Atrazine is found throughout the environment, even in the drinking water of millions of people across the country. Conventional water treatments are not effective in degrading this pesticide. Newer processes are more effective, but use chemicals that can leave toxic by-products in the environment.
