In our last reel, Scott explained what decades of research at IISD Experimental Lakes Area have shown: phosphorus is the key nutrient driving algal blooms. But turning that science into action is another challenge.
Winnipeg’s North End treatment plant is the largest point source of phosphorus to Lake Winnipeg. Full upgrades are expected to cost more than $3 billion and will not be completed until sometime in the 2030s.
LWF and IISD proposed a low-cost interim solution using ferric chloride, which is already used at the plant. Adjusting where and how much is added could reduce phosphorus sooner.
With Winnipeg’s municipal election approaching, this is a question worth asking every candidate: Will you support timely, evidence-based phosphorus reduction at the North End treatment plant while the full upgrades continue?
