3. Just because it's fresh does not mean you can drink it.

Potable (or drinkable) water is derived from freshwater, but has been filtered or treated for human consumption and use.

4. Freshwater can be found both on and underneath the Earth's surface.

Groundwater can be found in soil or housed in fractures in underground rock formations. Aboveground freshwater can take the form of ice (sheets, caps, bergs, glaciers), still water (bogs, ponds, lakes), or running water (rivers, streams).

5. Only 2.5–2.7% of all water on Earth is freshwater.

And the majority of it is frozen in ice caps, glaciers, or snow.

6. Nearly all freshwater comes from precipitation (rain, snow, mist) from the atmosphere.

Thusly, this precipitation can sometimes pick up environmental characteristics, which will then have effects on the still and running water systems it precipitates back into.

7. Rain-bearing clouds that come into contact with air pollution found in industrialized areas can cause acid rain.

Acid rain can have negative effects on plants, animals, and infrastructure.

8. All living organisms need water to survive, but some mammals with limited to no access to water can generate it themselves.

Desert rodents are known to generate water through the metabolization of certain seeds.

9. Some fish and aquatic creatures can move between fresh and saltwater environments.

Salmon and eel are known to use the hormones cortisol and prolactin (respectively) to assist in this process.

10. A quarter of the Earth's freshwater supply can be found in just three African Great Lakes.

The African Great Lakes are separated into a number of individual lakes, including Lake Victoria, Lake Tanganyika, and Lake Malawi, three of the largest lakes in the world that, combined, contain 25% of the world's freshwater.

11. A dairy cow consumes on average 20 gallons of water per day.

While humans need approximately two to three liters of water per day.
