But… but… the mayor went for a swim and said it was clean. /s

I am guessing it was clean enough in that specific section for a quick swim but not long term exposure.

Edit- I should specify that I understand from the article that the rain caused the worry. If the Seine was truly clean enough the rain should not have been able to tip it over the edge from good to bad.
