Aquifers and Groundwater, from USGS Water Science for Schools. I hope you appreciate my spending an hour in the blazing sun to dig this hole at the beach. It is a great way to illustrate the concept of how, below a certain depth, the ground, if it is permeable enough to hold water, is saturated with water. The upper surface of this zone of saturation is called the water table.
The saturated zone beneath the water table is called an aquifer, and aquifers are huge storehouses of water. What you are looking at in this picture is a "well" that exposes the water table, with an aquifer beneath it. Of course, I am cheating here, as at the beach, the level of the water table is always at the same level as the ocean, which is just below the surface of the beach. Groundwater is one of our most valuable resource—even though you probably never see it or even realize it is there. As you may have read, most of the void spaces in the rocks below the water table are filled with water. Sometimes the porous rock layers become tilted in the earth.

There are three types of aquifers and they are unconfined, confined and perched. In the unconfined aquifers, the water table is located at the outermost part of the aquifer. The water in the confined aquifer is usually the water that receives runoff, snowmelt etc. To keep it simple, unconfined aquifers have no confining layers. The confined aquifer has confining layers between the water level and the ground level. The water in this type of aquifer runs between two beds of impermeable layers. The final type of aquifer is known as the perched aquifer. Perched aquifers are aquifers that have no confining layer below the ground level and sit above the main water table.[2], [3] Figure 1 Schematic of confined and unconfined aquifers. Source: USGS Figure 2 Schematic of perched aquifer. Aquifers are recharged (re-filled) by both natural and man-made means. Figure 3 Schematic showing various means by which aquifers are recharged.

Groundwater facts - National Groundwater Association. Groundwater is the water that fills cracks and other openings in beds of rocks and sand. Each drop of rain that soaks into the soils moves downward to the water table, which is the water level in the groundwater reservoir. Groundwater does not normally occur in underground streams, lakes, or veins. Groundwater is found in soils and sands able to retain the water — much like a sponge holds water. Some 2.78 million trillion gallons of groundwater, 30.1 percent of the world's freshwater, are estimated for the entire planet of Earth. [1] Of the total 349 billion gallons of freshwater the United States withdraws each day, groundwater is estimated to be 79.6 billion gallons, or 26 percent. [2] There is a relationship between groundwater and surface water.
About a quarter of all U.S. rainfall becomes groundwater. Groundwater is a significant water supply source — the amount of groundwater storage dwarfs our present surface water supply. Groundwater is a renewable resource. [8] Ibid. [14] U.S. The Groundwater Story. Understanding Groundwater - Part 2. Understanding Groundwater - Part 1. Science Bulletins: Water Underground. Thirstin's Water Cycle. Water Cycle - Animated Diagram. Kids Zone: Our Water Water is an invaluable resource; we absolutely cannot live without it. Did you know that you can survive about a month without food, but only 5 to 7 days without water? That is because about 60 percent of the human body is made up of water: the brain is composed of 70 percent water; blood is 82 percent water; and the lungs are nearly 90 percent water! In order to stay healthy, human beings should drink about 8 cups of water per day. Well, we already know that our bodies use a lot of water, but have you ever stopped to think about all of the different ways you use water in your life every day?
We use water all of the time in our homes, at school, and even while we play. Where does all of this water come from? Did you know that around 70-75% of the earth is covered in water?
