Winnipeg student to confront algae blooms at international competition

'By reducing high amounts of phosphorus ... we’re essentially able to reduce the growth of blue-green algae,' explains Manitoba student Baljot Rai of his winning science project.

Manitoba student Baljot Rai may have found a way to address a growing problem in our province’s waterways, and he’s hoping to take it all the way to Sweden.

The project in question is one which uses a problem to confront another.

Having won a national competition over the weekend in Edmonton, Rai is hoping to take his findings to the next level. His project looks at how to take excess phosphorus out of Lake Winnipeg, which is causing blue-green algae blooms, using shells from the province’s waterways.

The Grade 11 student crushed and processed blue mussel shells in a lab, then applied the powder to samples which were adjusted to mimic the water of Lake Winnipeg.

He found it absorbed approximately 60 per cent of the phosphorus from the water through a bind with the mussels’ calcium carbonate, bringing the levels close to that of a healthy body of water.

“By reducing that high amount of phosphorus from the waterbody we’re essentially able to reduce the growth of blue-green algae,” Rai told Global News’ Iris Dyck.

Rai’s experiment initially earned him a prize at the Bison Regional Science Fair, held each year in Manitoba. Top earners are then invited to compete in the Canada-Wide Science Fair, which was held in the Alberta capital this year.

The St. Paul’s High School student was one of three finalists chosen for the Canadian Stockholm Junior Water Prize at the annual competition. If his project is picked based on a submitted report, he will compete for the prize in Sweden later this summer.
