How much fresh water is on the Earth?
3% of the earth’s water is fresh. 2.5% of the earth’s fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth’s surface to be extracted at an affordable cost. 0.5% of the earth’s water is available fresh water.
Where is all the water going?
Over millions of years, much of this water is recycled between the inner Earth, the oceans and rivers, and the atmosphere. This cycling process means that freshwater is constantly made available to Earth’s surface where we all live. Volcanoes release massive amounts of water from the inner Earth to the atmosphere.
What percent of salt water is on Earth?
97 percent
Over 97 percent of the earth’s water is found in the oceans as salt water. Two percent of the earth’s water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth’s water available to us for our daily water supply needs.

Where does most of the world’s drinking water come from?
It acts as a reservoir that can also be tapped for various uses including in agriculture and industries. Groundwater provides approximately 40% of the drinking water. Another important source of drinking water is the surface freshwater. The surface water is held in lakes, rivers, dams, and streams.
