The organizers of the Tokyo 2020 Olympics and Paralympics on Friday said they are confident next year¡¯s outdoor swimming races won¡¯t be canceled like the test run in August was, thanks to measures to keep E. coli bacteria at acceptable levels.

Water-quality tests at Odaiba Marine Park during the summer revealed that triple filtering screens kept E. coli levels within agreed upon limits, the organizing committee announced at a news conference.

¡°Unless a massive typhoon were to strike leading up to the events, we are confident that there will be no problem in hosting athletic competitions at Odaiba Marine Park,¡± said Kaori Akiya, general manager of the venue.
