If you ask people what's the color of water, they'll most probably automatically say "blue" or transparent. What happens if they see their streams in a shade of pink or green? Typically, they'll be surprised. See what happened in these countries and why their waters turn to another color.

Canada. People from Onoway, Alberta woke up with their toilets and taps water turned to pink. Concerns were raised, and investigations took place. It was found out that a chemical called potassium permanganate got into a reservoir after finding a certain a valve have gotten stuck somewhere. Potassium permanganate, when dissolved in water, turns pink. It had affected the whole town when it flowed to the Onoway's water distribution system.

Australia. The waters of Australia have turned into pink because of climate conditions--a combo of rain, warm weather, and little rainfall was responsible for turning the salt lake of Melbourne into a pinkish lagoon. This is a natural phenomenon that also happens in Spain's Salina de Torrevieja and Senegal's Lake Retba. A single-celled matter called Dunalliela is responsible for turning it pink.

Spain. The waters have become green, but it's not yet St. Patrick's Day. The Andorran Ministry of Health has intentionally dyed the waters green due to research on a water bottling plant. According to ABC News: "The plant was reportedly linked to a gastroenteritis outbreak in Catalonia last year that left thousands of people sick after they drank from contaminated office water coolers."

San Francisco. The San Francisco Bay usually has emerald green waters, but suddenly turned brown after soil and rock sediments were battered by heavy storms. According to scientists, the color may not be pleasing, but it's considered as beneficial for the health of the Bay. It helps in the creation of mud flats and marshes which are considered as habitat for wildlife in the area.
