Tokyo 2020 Olympic organizers find high bacteria levels at open-water swim venue
Japan Today -- Oct 05
Tokyo 2020 Olympic organizers said on Wednesday that tests showed levels of E. Coli up to 20 times above the accepted limit and fecal coliform bacteria seven times higher than agreed at the planned venue for marathon swimming and triathlon.

Organizers 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 fecal 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.

Tests carried out during 26 days between July and September showed that water quality standards set by the international federations were met on only 10 days for marathon swimming and just six days for triathlon.

For example, the quantity of fecal coliforms tested on one day as high as 7,200 per 100 milliliters, well above the limit of 1,000 per 100 ml agreed by the International Swimming Federation.

Meanwhile, escherichia coli (E. Coli) tested as high as 5,300 per 100 ml, compared with the International Triathlon Union's ceiling of 250 per 100 ml, the Tokyo 2020 organizing committee and Tokyo Metropolitan Government said in a statement.

Fecal coliforms come from human and animal waste and a large amount could indicate illness-causing bacteria is also present, while some strains of E. Coli can cause diarrhea or illness.

Tokyo officials laid much of the blame on a near-record 21 straight days of rain in August, saying the water quality at Odaiba varies significantly depending on the weather, and expressed confidence they could control the situation.

Still, they acknowledged the water quality already needed to be improved around Odaiba Marine Park, which is in a popular tourist district on Tokyo Bay.
