The 2024 Summer Olympics are underway in Paris, with competition lasting until mid-August.

Paris Olympics

The men's and women's Olympic triathlons were successfully held in Paris’s Seine River after water tests met IOC safety standards just hours before the events were scheduled. Despite concerns over water quality, the river was deemed safe for the athletes to swim.

Paris officials invested two billion Canadian dollars to ensure the Seine was swimmable. Measures included constructing a giant basin to capture excess rainwater and prevent untreated sewage from entering the river. However, intense rain could still cause some overflow, potentially introducing bacteria like E. coli into the water.

Health Canada's guideline for safe levels of bacteria in water is 235 colony forming units per 100 milliliters, while European standards and those used by the World Triathlon Federation allow for up to 900 units. Water samples taken prior to the events showed levels between 488 and 770, which were within the European safety limits.

An expert in water testing noted that understanding the full risks of swimming in the Seine could take years of study. For now, the focus for athletes was on competing, with some expressing a willingness to accept any potential health risks in order to participate in the Olympics.



Olympic triathletes dive into the Seine as water finally deemed safe

Diving into the Seine after days of delays over poor water quality the water finally deemed safe enough to swim. Probably the most beautiful venue of any race in the Olympics and I guess that came with a small penalty of the risk of the Seine being dirty. Paris officials poured two billion dollars Canadian to make the river swimmable. A giant basin was built to capture excess rainwater and keep untreated sewage from flowing into the river. But it is very difficult to capture all of the water when there's intense rain. So some of it can overflow. Pushing bacteria like E. coli into the river. Health Canada's guideline when it comes to safe levels is 235 colony forming units per 100 milliliters of water. But by European standards the safe limit is 900. The World Triathlon Federation uses the same criteria. These are European standards within the context of what's achievable in Europe. What is acceptable culturally in Europe. Water samples taken Tuesday showed levels had fallen to between 488 and 770. What I can say is that we followed rigorously the process. This water testing expert says understanding the risks of swimming in the Seine can take years of study. But in the meantime. I guess we will see in the next days if there are people getting sick or not. For athletes competing the focus was singular. I think we were just stoked. We're racers at heart right? That's what we came to do. We came to race at the Olympics. If I have poison after or if I get sick I don't care. I did the triathlon. The hope for some is that well after the summer Olympics are done there will be a cleaner swimmable Seine for Parisians to enjoy. Idil Moussa, CBC News, Toronto.
