Tokyo 2020 Olympic organisers said on Wednesday that tests showed levels of E. Coli up to 20 times above the accepted limit and faecal coliform bacteria seven times higher than agreed at the planned venue for marathon swimming and triathlon.
Organisers have vowed to improve the water quality to ensure the safety of athletes, including through installing underwater screens at Odaiba Marine Park to limit the amount of faecal coliform bactria flowing from offshore during rainy periods.
They also said they would consider amending event dates and times during the Games in response to weather conditions.
“We will take the best possible measures to make sure that the venue satisfies all relevant standards of international federations and that athletes can perform at their best feeling very safe,” Koji Murofushi, Tokyo 2020 sports director, told a news conference.
