 Well, weeks before the Olympic Games are set to begin in Paris, the River Seine is still not safe for swimming on most days due to the high levels of E. coli bacteria in the water. The triathlon is planned to start later this month, and official testing shows E. coli above acceptable levels on majority of days. But authorities say there has been general improvement in the Seine's water quality, and they are confident for the Olympics. The opening ceremony of the Paris Olympics is set to take place on the Seine on July 26th.
