Water quality concerns force cancellation of Paris Olympics swimming test events in Seine River

Water quality tests showed high bacteria levels and inconsistencies, leading to cancellation of paratriathlon and mixed relay swimming events.
Heavy rainfall may have contributed to increased pollution levels in the Seine River where events were to be held.
Cancellations are a setback for Paris 2024 organizers who planned to hold Olympic swimming events in the open-air Seine.
Paris is investing in water management infrastructure projects to improve water quality and make the Seine swimmable.
Organizers remain committed to hosting Olympic swimming in the Seine but have backup contingency plans if water quality issues persist.
