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.
It is possible to coat droplets of water with silica, resulting in a dry powder known as “dry water”.
Most toilets in Hong Kong are flushed with seawater in order to conserve the city’s scarce freshwater resources.
In 2013, after more than 20 years of soda being America’s number one beverage, water has taken over as Americans’ favorite drink.

Tap water from ancient Rome likely contained up to 100 times more lead than local spring water. Some historians link fall of the Western Roman Empire to lead poisoning
