What is groundwater

Groundwater is water that comes from the ground. Sounds easy, doesn't it? Amazingly, many people use groundwater but don't even know it. In fact, half of everyone in the United States drinks groundwater everyday! Groundwater is even used to irrigate crops which grow food for tonight's dinner.

 

Where does groundwater come from? Groundwater comes from rain, snow, sleet, and hail that soaks into the ground. The water moves down into the ground because of gravity, passing between particles of soil, sand, gravel, or rock until it reaches a depth where the ground is filled, or saturated, with water. The area that is filled with water is called the saturated zone and the top of this zone is called the water table. Makes sense, doesn't it? The top of the water is a table! The water table may be very near the ground's surface or it may be hundreds of feet below.

Think about this: have you ever dug a hole in sand next to an ocean or lake? What happens? As you're digging, you eventually reach water, right? That water is groundwater. The water in lakes, rivers, or oceans is called surface water...it's on the surface. Groundwater and surface water sometimes trade places. Groundwater can move through the ground and into a lake or stream. Water in a lake can soak down into the ground and become groundwater.

Groundwater is stored in the ground in materials like gravel or sand. It's kind of like the earth is a big sponge holding all that water. Water can also move through rock formations like sandstone or through cracks in rocks.

An area that holds a lot of water, which can be pumped up with a well, is called an aquifer. Wells pump groundwater from the aquifer and then pipes deliver the water to cities, houses in the country, or to crops.

Most groundwater is clean, but groundwater can become polluted, or contaminated. It can become polluted from leaky underground tanks that store gasoline, leaky landfills, or when people apply too much fertilizer or pesticides on their fields or lawns. When pollutants leak, spill, or are carelessly dumped on the ground they can move through the soil.

Because it is deep in the ground, groundwater pollution is generally difficult and expensive to clean up. Sometimes people have to find new places to dig a well because their own became contaminated.

Some Questions To Ask A Parent, Grandparent, Or Teacher:

  • Where does our water come from?
  • How does it get to our house?
  • Has our water ever been polluted? If yes, what was the cause?

If adults don't know the answer, call or write a letter to your city water company or mayor's office. If you have a well near your home, locate it and talk to your parents or other adults about keeping pollution away from it.
