Water quality data utilized by Paris Olympics organizers indicates that bacteria levels in the Seine River were generally within acceptable thresholds on the days when athletes swam in the iconic waterway. The data, obtained by The Associated Press, includes daily tests for fecal bacteria E. coli and enterococci at four sampling points in the river.
The testing period spanned from July 19, a week before the opening ceremony, through the days when marathon swimmers competed in the river. Despite the river's historical pollution issues, Paris invested 1.4 billion euros in infrastructure improvements to enable Olympic events like triathlon and marathon swimming to take place in the Seine.
