Paris: the quality of the water in the Seine is improving, will the Olympic Games still take place? An ambitious environmental challenge for 2024.

qualité eau seine

As the Olympic Games approach, the water quality of the Seine River is a concern. Recent analyses were conducted by the City of Paris between the 1st and 9th of June. The results show an improvement, but they still remain below the recommended levels for swimming competitions that are scheduled to take place in this river.

During a previous examination in April, the NGO Surfrider Foundation had raised the alarm about this worrying situation. Indeed, out of the 14 samples taken at that time, 13 exceeded the established standards for safe bathing.

Following the controversies surrounding this crucial issue, Benjamin Raigneau, director of water and cleanliness in Paris, emphasized the importance of obtaining regular measurements to monitor the bacteriological evolution of the river and identify significant trends.

With these health issues in the background and despite the efforts made to improve the situation, it remains essential that each step taken towards better quality be scrutinized rigorously so that athletes can participate without risk during the events planned in a few weeks.

Exceeded bathing thresholds

Researchers analyze the Seine to determine if the water is suitable for swimming. They look for two specific bacteria: Escherichia coli and enterococci, which indicate fecal contamination. For the water to be considered safe, there should be no more than 1000 CFU/100 ml of Escherichia coli and 400 CFU/100 ml of enterococci.

According to the latest results published by the city, the water quality is slightly improving, but still below the required standards for swimming. The tests show that these thresholds were exceeded almost every day except one. However, the level of enterococci is gradually decreasing, raising hopes for future improvement.

The variability of the data depends heavily on weather conditions such as precipitation, heat, and UV exposure. In hot and sunny weather, bacteria die faster. The flow of the Seine also plays a crucial role: the higher it is, the faster pollution disperses.

Benjamin Raigneau explained that several factors influence these results:

  • Ambient temperature
  • Drought or rainfall
  • Sunlight exposure
  • River flow

In conclusion, despite some notable progress in the water quality of the Seine, it is still not ready to accommodate swimmers without significant health risks such as gastroenteritis or conjunctivitis.

Hope for the Olympic Games

Recently, Anne Hidalgo postponed her swim in the Seine. Initially scheduled for the end of June, it will take place after the legislative elections. However, the Mayor of Paris promises to swim before the start of the Olympic Games.

For the Olympic events, Benjamin Raigneau remains confident. The reduction of pollution and better weather conditions could benefit the Olympics. To follow the evolution of the situation:

  • A weekly weather report for the Seine will be available on the City of Paris website until the end of September.
