A professor at the University of Moncton is introducing fine clay into the city’s Irish Town reservoir in the hope of halting its blue-green algae problem.
The clay absorbs phosphate, cutting off the food supply to the potentially toxic algae, which can cause diarrhea, headaches, vomiting and fever.
Professor Alyre Chiasson is applying the clay product called Phoslock to one small area of the reservoir as a pilot test. According to a CBC report, Chiasson said the product has been used successfully in Ontario and Australia.
Blue-green algae is a growing problem in Canada’s lakes.
