The South Saskatchewan River is not as clean as you might think.
Contaminants, such as gas and pesticides, left on city roads seep into the river, potentially affecting communities downstream, according to The Meewasin Valley Authority. Unlike wastewater, the storm water isn't treated before flowing into the South Saskatchewan River.
The issue of wastewater was front and centre on World Rivers Day, Thursday, September 29, an event that aims to keep contaminants out of storm drains and pollution of the river.
Dr. Kerry McPhedron, GIWS member and an Assistant Professor with the College of Engineering, spoke to the media about the costs of the infrastructure needed to treat the water that goes into our rivers.
