We were shocked when we read about the levels of water pollution in Guanabara Bay that sailors and rowers competed in, and saw the waters of the diving pool turn a sickly green during the 2016 Rio Olympics.
And yet, here we are a year later, and we learn of the significantly polluted waters of Tokyo Bay, the intended site for triathletes and open-water swimmers.
According to Inside the Games, the Tokyo Metropolitan Government conducted a water quality test in Tokyo Bay over a 21-day period, which is a sample size as long as the actual Games themselves. The results, which were shared at an October gathering of the IOC Coordination Commission in Tokyo, showed “levels of E. Coli up to 20 times above the accepted limit and faecal coliform bacteria seven times higher than the permitted levels.”
This Asahi News article quoted organizers as saying that “an inflow of raw sewage caused below-standard water quality in more than half of tests conducted.” Officials explained that “heavy rain caused overcapacity at sewage processing plants, and some of the untreated sewage flowed into Tokyo Bay,” and that “they are considering such measures as installing triple layers of a screen that can block the flow of coli bacillus.“
Is there any consideration to move the venue for the triathlon and the open-water swimming events?
Sports Director of the Tokyo 2020 Organizing Committee, Koji Murofushi, shut that idea down, stating that “measures will be taken so that we can provide an excellent environment for the sports.”
The truth of the matter is, there have been signs in the area planned for the Olympic events for years warning people not to swim in the bay. Will the organizers figure out to clean up this act? We’re a little more than a thousand days away. Tick tock.
