How wildfires can have a devastating, long-term impact on nearby water supplies

How wildfires can have a devastating, long-term impact on nearby water supplies

Some researchers thought her team wouldn't even be able to detect an impact from the fires because the Athabasca River was already looking like tea before the fires. Heavy rains tend to send hot fudge-looking runoff from the land into the river, making it look like chocolate milk, she said. Arriving after the fires, Emelko said she could see that hot fudge-looking flow enter the Athabasca's waters as ash, likely carrying nutrients like phosphorous and carbon, made the water supply challenging for treatment processes. "Those [workers] were living in the water treatment plant, working hard to make sure that people could return to their homes and at least have safe water to drink," Emelko told Day 6 host Brent Bambury.

Hailed as green energy source, northern Quebec lithium project divides Cree

Hailed as green energy source, northern Quebec lithium project divides Cree

According to the promoters, the region contains some of the world's largest deposits of spodumene, a rock from which lithium — key to the energy transition and the electrification of transport networks — is extracted. Nemaska Lithium describes itself as a corporation that "intends to facilitate access to green energy, for the benefit of humanity." The Whabouchi open pit mine will be located about 30 kilometres from the village of Nemaska, in the watershed of the Rupert River, considered one of Quebec's ecological gems. "If the water becomes contaminated by the mine, I don't see how we can limit the damage to the food chain," says Thomas Jolly, who was chief of Nemaska from 2015 to 2019, stressing the importance of fishing to his community.

Well water fears prompt calls to halt proposed bottling plant near B.C. village

Well water fears prompt calls to halt proposed bottling plant near B.C. village

The proposed water-bottling plant has raised concerns from the High Bar First Nation over the aquifer's long-term sustainability, and has fuelled calls for a moratorium on groundwater bottling licences issued by the province. Greg Crookes, a natural resource manager for the High Bar First Nation, says the community has been in regular talks with the province, each time strongly opposing the plant. "If we say yes to extracting some water now, what's that going to look like 10, 20, or 100 from now?" said Crookes. He says the area only gets about 28 centimetres of precipitation per year, the same figure included in Environment Canada's precipitation records for the years 1981 to 2010. "If they need water, go to the places where the water exists — don't go to some of the driest places in B.C.," he said. "The ranchers need the water, the First Nations need the water, the animals need the water."
