Once swamped with garbage, there are now swimmers in this Toronto lake basin | CBC News
"Just months ago, Steve Mann was scooping stinky garbage and hauling decomposing animal carcasses out of the Peter Street Basin. Now, he's swimming in it. The University of Toronto professor has made it his mission to clean up the strange pool of lake water at the base of condos off of Queens Quay, across from HTO Park. The stench here was so unbearable, people didn't even want to come near it, said Mann."
"So Mann and an eager team of volunteers, including many of his students, started cleaning, hauling bags and bags of garbage out of the basin. They experimented using tech including robot submarines but there was so much trash, pool nets proved the most efficient method. Mann kept an eye on E. coli levels, testing in his university lab and working with professors who specialize in water quality."
Steve Mann led volunteer cleanups to remove large quantities of garbage and decomposing carcasses from the Peter Street Basin beside Queens Quay. The basin had been foul-smelling and visually polluted, prompting regular manual removals and experiments with technology, though pool nets proved most effective. Mann monitored E. coli levels in his university lab and coordinated with water-quality experts. Toronto's safety threshold for swimming is 100 E. coli per 100 millilitres. Recent samples from the basin measured about seven to ten E. coli per 100 millilitres, well below the safety limit, and Mann now swims there.
