Seine fit for swimming most of past 12 days, Paris says ahead of Olympics

Paris city hall announced that the Seine has been clean enough for swimming for most of the past 12 days, just weeks ahead of the Olympic Games. The river will be the star of the opening ceremony of the Games on July 26 and will host the triathlon and swimming marathon. However, unseasonally heavy rain has raised pollution levels due to untreated sewage washed into the river.
