There were previously concerns the race could be pushed back after heavy rain on Wednesday and Thursday caused levels of bacteria in the water to rise once again.
Germany managed to secure the gold medal in the event, followed by the US with silver and the UK with bronze.
Morgan Pearson, who competed in the event for the US, described the water as ‘quite brown’.
He also admitted to having some reservations ahead of the event, saying: “We were looking out the window constantly thinking: ‘Oh no, it’s raining again’.”
Water samples of the Seine are being taken daily during the Olympics so organizers can assess the risks of swimming in the river.
