Storyboard Text

  • That's a great question! Groundwater is water that moves through and is stored in pore spaces in the ground.
  • Hi Mr.Thomas! What is groundwater? I heard of that word but could never find out what it meant. 
  • The groundwater that fills the spaces between fractured rock. Fractured rock is any kind of separation in a rock formation. The faults(cracks in the earth's crust) in the rock act as barriers and change the direction of groundwater flow.
  • Water is stored in what is called an aquifer. An aquifer is a body of rock through which water flows and is stored.
  • Where is the water being stored in the underground? Also, what are pores?
  • Pores are frefered to as the volume of solid voids that can be filled with water or air.
  • First of all, you have the unsaturated zone.  This is the portion of the subsurface above the groundwater table. Then comes the water table. The water table is the level below the ground that is saturated with water. Saturated meaning thoroughly soaked with water. After the water table comes the zone of saturation, which is the ground below the water table that is saturated with water.
  • What are the layers?
  • Groundwater contributes toward the surface water! Surface water means any water that collects on the surface of the earth. 
  • Another fun fact is the water that collects in the tree roots eventually give off water vapor through the pores of their leaves. This process is called transpiration.
  • That's so cool!
  • Super!
  • Although groundwater is an excellent source of drinking water, it can also be contaminated with toxic chemicals. Such as pesticides, fertilizers and oil can be runoff and seep into the permeable ground. These harmful chemicals can take many years if possible to clean.
  • Wow! I didn't know that we humans cause all these harmful chemicals in our water! Now I will be more careful.
  • Thanks for your lesson!
  • How can fix this from happening?
  • Simply, we can store pesticides, fertilizers and other cheimcal far away from a well.
