Ahead of the 2024 Summer Olympics in Paris, concerns arise over the water quality of the Seine River, a critical venue for triathlon and marathon events. Recent rainfall has compromised water quality, leading to the cancellation of practice runs and raising concerns about the health of athletes. Experts discuss the potential risks and mitigating measures taken to ensure safety.
For over a century, swimming in the Seine River has been forbidden due to severe water pollution. The mixture of sewage and storm runoff in a single pipe has resulted in dangerously high levels of bacteria and contaminants.

In anticipation of the Olympics, Paris has invested heavily in water treatment and infrastructure. An underground storage basin and upgraded sewer systems aim to prevent wastewater overflow into the river during heavy rainfall.
Daily water quality testing is conducted throughout the Olympics to ensure compliance with safety standards. Tests primarily focus on total coliforms, while other pathogens may not be routinely monitored.

Despite treatment efforts, the Seine River harbors various microorganisms that can cause illness. Swallowing contaminated water poses risks for gastrointestinal infections, while skin and eye infections are possible through contact with abrasions. Parasites and viruses also present significant health concerns.
E. coli, a common indicator of fecal contamination, can lead to severe gastrointestinal distress. Other bacteria associated with sewage, such as Enterococcus, Salmonella, and Campylobacter, pose similar health risks.

Giardia, amoebas, and Cryptosporidium are parasites found in human waste that can cause intestinal infections. Viruses like norovirus, hepatitis A, and hepatitis E can also be present in contaminated water.
Leptospires, bacteria found in rodent urine, can cause leptospirosis, a potentially severe bacterial disease with flu-like symptoms and potential kidney damage.

Athletes with compromised immune systems face greater health risks. Preventive measures include pre-competition medical screenings, vaccinations, and prompt medical attention in case of illness.
Heavy rainfall on Friday and Monday led to the cancellation of triathlon practice runs due to elevated bacteria levels. Despite improvements in water quality, the men's triathlon was ultimately postponed due to unacceptable levels at certain points of the swim course.
