Pools Turn Green at Rio Olympics

Pools Turn Green at Rio Olympics
The outdoor diving pool at the Rio Olympics turned green this week, leaving many wondering if the water was safe for athletes to swim in. Though the cause of the discolouration is currently unknown, officials say the water has been tested thoroughly and there is no risks to athletes. There are several theories about why the pool would turn green. Some pool experts believe it is a build up of algae while others say it’s due to a lack of chemicals. Shortly after organizers assured athletes that the diving well would be blue again soon, the adjacent water polo pool turned green as well.

2. The reason for the discolouration is unknown, but it could be caused by algae or a lack of chemicals.
