Paris 2024 chief 'confident' River Seine will be used

Paris 2024 president Tony Estanguet is "confident" it will be possible to use the River Seine at the Olympics this summer, despite latest results showing it is still failing water quality tests.

The Paris mayor's office released results of the most recent tests done, which showed the levels of E.Coli remain above the upper limits imposed by sports federations. On 18 June, the level of E.Coli was 10 times the acceptable level and did not fall below the upper limit of 1,000 colony-forming units per 100 millilitres (cfu/ml) used by the World Triathlon Federation.

"Water quality remains degraded because of unfavourable hydrological conditions, little sunshine, below-average seasonal temperatures and upstream pollution," the mayor's office said in a statement. The Olympics start on 26 July, with the men's and women's triathlon scheduled for 30 and 31 July respectively and the mixed event on 5 August.

The Seine is also set to host marathon swimming at the Olympics on 8 and 9 August and the Para-triathlon event at the Paralympics, which start on 28 August.
