In Warsaw’s Gruba Kaśka water plant there are eight clams with sensors attached to their shells. If the clams close because they don’t like the taste of the water, the city’s supply is automatically shut off.
Maya people at the ancient city of Tikal in Guatemala used a mineral called zeolite to decontaminate drinking water in one of their large reservoirs. It’s the oldest known example of water purification in the Western Hemisphere.
Icebergs are always made out of fresh water. True icebergs are glacier fragments that have fallen into the sea. Glaciers are composed of fresh water, and thus true icebergs are too. Additionally, ‘sea ice’ that forms from frozen sea water is also fresh- this is because the salt is excluded from the ice crystal lattice that develops when water freezes.
It takes 15 gallons of water to produce just 16 almonds and they rely on pesticides to grow successfully; the popularity of Almond Milk is causing environmental and sustainability problems in California where 80% of the world’s almonds are grown.
An annual supply of bottled water for a person who consumes 8 glasses a day would cost approximately $200; the same amount of tap water would cost approximately $0.33.
The world’s purest fresh water has been found on the southern tip of Chile, in a town called Puerto Williams, after numerous scientific studies. The water has been found to have only two chemical parts per million, hence making it the world’s cleanest.
New York City is one of four major cities in the United States whose drinking water is pure enough not to require purification by water treatment plants. The city is supplied with drinking water by the protected Catskill Mountains watershed.
Japanese vending machines are operated to dispense drinking water free of charge when the water supply gets cut off during a disaster.
There is liquid water on Mars. The watery area in question is about 20 kilometers in diameter, and while depth can’t be determined, the deposit would likely have to be at least a meter thick to produce the reflection observed. So at a bare minimum we’re probably looking at a serious quantity of water, on the order of millions of liters.
“It’s not anything you’d want to swim in — negative 80 degrees Fahrenheit, or negative 60 Celsius, and probably more of a thick sludge subsiding here and there into “brine pools.” If I’m not mistaken you’d probably also be crushed like a bug if you weren’t inside some kind of pressure vessel. Still — it’s liquid water. On Mars. Today.”
There’s a max height that water can be sucked up a straw: 10 meters. At 10 meters, a perfect vacuum is created at the top of the straw, and water will begin boiling spontaneously.
