Since the modern Olympic Games were revived in 1896, no city has ever hosted swimming events in an urban river. Too poopy. But Paris, as we talked about, hopes to be the first. Starting on July 30, the Seine is scheduled to host the swimming portion of the triathlon competitions.

Except, it will depend on water quality. Today's training sessions (scheduled for Sunday, July 28) were cancelled because water tests showed that the Seine is currently below acceptable standards. This is due to heavy rain over the last few days, which I guess overloaded the city's storm network.

So what is clear is that -- 36 years after then-Mayor Jacques Chirac first promised to clean up the river -- the city has only been able to successfully achieve this, sometimes. It's not an easy task.

According to Bloomberg, the clean-up efforts have already cost €1.4 billion. This was spent on doing things like constructing a 50,000 m3 holding basin (about the size of 12 Olympic-sized pools) under the Gare D'Austerlitz. This now holds storm overflow during heavy rain events, in lieu of it going into the Seine.

But this doesn't provide any guarantees as evidenced by today's cancelled training sessions. Presumably, it just makes it less likely for overflow stormwater to get dumped into the Seine. So a cynic might ask: Why bother with all of this?

Well, for one thing, swimming in a river in the middle of a major global city is just plain cool. Look at how the Swiss do it. But another reason could be that you want to create one of the greenest cities on the planet. And if that's the case, then seeing athletes swimming in the Seine is a pretty powerful image.

It shows progress.
