Freshwater Statistics

About 71% of the earth's surface is covered in water.
About 97.5 % of the water is saltwater.
That leaves about 2.5 % freshwater.

Almost 70% of that freshwater is locked in glacial ice.
Almost 30% of that freshwater is trapped in ground soil.

That leaves less than .0007% of all water on earth accessible for direct human use.

This is the water found in lakes, rivers, reservoirs, and tappable unground sources.
This .0007% is renewed through rain and snow fall.
