Where is the Rest of Earth’s Water?

You know, that 3% that is not in the oceans? Just 3% of the total Earth water supply is not in the oceans. But it is still A LOT OF WATER! —approximately 2,030,000 cubic miles of water. Most of this 3% of usable water is frozen in glaciers and ice caps, mainly in the Arctic, Antarctica, and Greenland. This “frozen” water is 77% of the non-ocean supply. 22% of the Earth’s water that is not in the oceans is “groundwater” that we use for drinking, bathing, irrigation and watering our plants. The remaining portion, less than 1%, is in rivers, lakes, and stored in the soil above the aquifers (the unsaturated zone) as moisture.
