Seine River's Water Quality Remains a Concern Ahead of Olympic Swimming Events

The Seine River in Paris has been illegal to swim in for over a century. Despite this, the city has invested 1.4 billion euros ($1.5 billion) in infrastructure to improve water quality by capturing more stormwater during rainfall events. Official testing shows that E. Coli levels at Alexandre III Bridge have been above acceptable levels on most days, contradicting claims of a general improvement in water quality. In fact, official data suggests that the Seine is still not safe for swimming on most days.
