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.

Researchers and Indigenous students learn about Grand River

Researchers and Indigenous students learn about Grand River

On June 15, grade nine students from Six Nations Polytechnic (SNP) and the STEAM Academy program donned their waders to join researchers Charles de Lannoy, Karen Kidd and Waterloo Biology Professor Mark Servos to conduct experiments in the Grand River. In its first year, this joint initiative led by McMaster University and the University of Waterloo, is a land-based experiential learning approach to science and engineering. The event is a pilot for a micro-credential course in which the students could eventually gain a McMaster University credit by the end of high school.

BEYOND LOCAL: Indigenous youth are playing a key role in solving urgent water issues

BEYOND LOCAL: Indigenous youth are playing a key role in solving urgent water issues

Unsolved environmental problems, a national mandate to uphold treaty responsibilities and a new appreciation for positive treaty relationships are leading some water researchers to consider new approaches to their work. They are examining how water monitoring practices that are conventionally considered strong, can be improved. Recent research examined how water quality monitoring in the lower Grand River and nearby Lake Erie can inform management to address prolific growth of nuisance algae. Nuisance algae affect wildlife habitats and fishing, as well as swimming and boating. This work is part of the Lake Futures Group at the University of Waterloo and Global Water Futures, Canada’s largest water research collaboration.
