We now think we know what caused the green pool.
According to BuzzFeed, a spokesperson said the green water was due to a “sudden decrease in the alkalinity in the diving pool,” which apparently caused an algae bloom, therefore leaving the water green. The decrease in alkalinity that led to the algae was cause by “increased use of the pool in the last few weeks.”
Other sources agree, also adding that the hot weather could also be a catalyst for the sudden amount of algae. According to CNN, the Rio 2016 Local Organizing Committee says that “The green hue seen in the water was due to a proliferation of algae caused by the heat and lack of wind in the venue.”
