It can be a little tricky to figure out your exact hydration needs, but the National Academies' Institute of Medicine recommends that men get about 15.5 cups (3.7 liters) of fluids a day while ...
California's interconnected water system is the world's largest, managing over 40,000,000 acre-feet (49 km 3) of water per year, centered on six main systems of aqueducts and infrastructure projects.
Water exports from Canada to the US. A satellite image of North America. The Great Lakes are in the east, while the south-west clearly lacks water. Canada has 7% of the world's renewable supply of freshwater. [3] Freshwater export between Canada and the US currently takes place at a small scale, mostly as bottled water exports.

Water is the chemical substance with chemical formula H. 2O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [25] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.

Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
