PARIS — reveal contamination levels consistently above the safe limit of 900 colony-forming units per 100 milliliters determined by the World Triathlon Federation for competitions.
Persistent rainfall has exacerbated the issue, as rainwater infiltrates the sewer system, leading to the discharge of fecal bacteria into the Seine, the report said, adding that the flooding of the Yonne River, a confluence of the Seine, has increased the flow of the Seine. Marc Guillaume, the Paris region prefect in charge of the Seine, suggested the weather would improve in coming weeks.
