In a remarkable show of determination and confidence, 75-year-old American swimmer Joel Stratte McClure plunged into the murky waters of the Seine River in central Paris on Thursday. McClure's daring action aimed to celebrate the Fourth of July and shed light on the French government's commendable efforts to clean up the river in time for the upcoming Olympic Games.

McClure's timing could not have been better, as regional authorities later released data indicating a significant improvement in water quality over the past week. This positive development has raised hopes that the Seine River will be able to host Olympic swimming events as planned.

Recalling his last swim in the Seine River back in 1976 for a magazine cover shoot, McClure, who will turn 76 later this month, expressed both admiration for the progress made in cleaning up the river and concerns regarding its safety. He humorously stated before entering the water, "I may regret having swum, but if I come back alive, it will prove that the French have done a good job cleaning up the river."

Interestingly, Paris Mayor Anne Hidalgo had initially intended to swim in the Seine last month to demonstrate the river's cleanliness. However, her plans were postponed due to President Emmanuel Macron's announcement of snap legislative elections, which diverted attention from the pre-Olympic excitement. Additionally, heavy rainfall in recent months has led to stronger currents for this time of year, prompting Hidalgo to reschedule her swim for mid-July.

Undeterred by the challenges, McClure took a brief swim in the Seine River and declared the water to be "fantastic." He expressed hope that others would follow his lead and take advantage of the cleaner river.

With marathon swimming and triathlon events scheduled near the Alexandre III bridge during the Olympic Games from July 26 to August 11, and the Paralympics from August 28 to September 8, Paris remains optimistic about hosting these open-water events despite concerns about water quality.

While unsafe levels of E. coli were detected in the river last week, the latest test results from monitoring group Eau de Paris show a remarkable improvement. For all but one day between June 26 to July 2, contamination levels were found to be below the safe limit of 900 colony-forming units per 100 milliliters set by the World Triathlon Federation for competitions.

French officials are unwavering in their optimism and maintain that there is no Plan B for Olympic open-water swimming events. The concerted efforts made to clean up the Seine River in preparation for the Games have shown promising results, offering reassurance to both participants and spectators alike.

As the countdown continues, the transformative power of the Olympics once again demonstrates its ability to ignite positive change. The Fourth of July swim by Joel Stratte McClure serves as a testament to the progress achieved in cleaning up the Seine River, ensuring a memorable and safe experience for all involved in the upcoming Olympic events.
