French President Macron Delays Seine River Swim

French President Emmanuel Macron plans to swim in the River Seine to showcase its improved cleanliness due to depollution efforts, but no specific date has been set before the Paris Olympics. Macron's intention is to open swimming sites for residents in the future. The Seine's water quality has been suitable for swimming six out of seven days tested, with plans for Olympic events like the triathlon and swimming marathon. Despite improvements, concerns linger about hosting competitions due to variable E. coli levels and weather impacts on water quality.
