The Significance of the Seine
The River Seine serves as a defining feature of Paris, delineating the left and right banks and shaping residents' identities and activities. It has become a social hub where locals gather during warm evenings, enjoying wine and cheese along its banks, transforming it into a vibrant public space. As a highlight of the upcoming Olympics, the Seine will host significant events such as the opening ceremonies and swimming competitions, underscoring its cultural and recreational importance. The city's ambition is to present a cleaner Seine, aiming to restore its image and enhance the experience for both residents and tourists.
The Historical Decline of Water Quality
Historically, the Seine was regarded as a swimmable waterway, hosting swimming events during the 1900 Olympics, but pollution and sewage overflow caused a dramatic decline in water quality. The river's infrastructure struggles with an outdated sewage system that leads to dangerous bacteria proliferation, resulting in swimming bans since 1923. Attempts to modernize the sewage system began in the 1980s, but significant improvement remained elusive until the prospect of the Olympics spurred action. Committed to restoring the Seine, the city launched ambitious cleanup initiatives, driven by a newfound urgency to make the water safe for swimming once more.
Ambitious Cleanup Efforts and Challenges
To prepare for the Olympics, Paris implemented a $1.5 billion plan to rehabilitate the Seine, featuring both water quality improvement and infrastructural upgrades. Key strategies included constructing a large underground reservoir to manage stormwater and reduce sewage overflow, which has reportedly kept substantial amounts of pollution out of the river. Nevertheless, continuous rainfall poses a persistent threat, with fluctuations in water quality risking the feasibility of swimming events during the games. Despite the extensive preparations, the city's challenge lies in balancing ambitious goals with unpredictable environmental factors, as showcased by recent concerns over E. coli levels impacting scheduled Olympic swims.
Today, Olympics officials in Paris postponed the men’s triathlon because of elevated E. coli levels in the River Seine, where the event was set to take place. WSJ’s Joshua Robinson reports on how decades of trying to clean up the river may not have been successful.
