The iconic River Seine opened its banks to swimmers on July 5, marking the end of a swimming ban that had been in place since 1923 due to severe contamination in its waters.
For decades, the river has been polluted by E.coli, enterococci bacteria and other contaminants, with industrial waste, sewage overflow, and urban runoff making it unsafe for swimming.
Paris’s outdated combined sewer system, dating back to city planner Baron Georges-Eugène Haussmann’s 19th-century city planning, allowed untreated wastewater to flow directly into the river during heavy rainfall.
By the 1970s, about 60% of the city’s sewage was being dumped untreated into the river, and fish species had decreased to just three.
The historic reopening followed a €1.4 billion (US$1.6 billion) cleanup operation to make the river swimmable in time for the 2024 Paris Olympics, with open-water swimmers and triathletes competing in its specially treated waters.
Bastien Xu, a Parisian businessman who was among the first to take a dip when the ban was lifted, described it as a symbolic moment for the city: “The Seine River has always been seen as romantic, but now people can actually swim in it instead of just looking at it.”
“I was really excited. I felt lucky that we can swim there now after it wasn’t allowed for 100 years. My older French neighbors were envious because they never got the chance when they were young,” Xu told Earth.Org.
