**__Groundwater__ is water contained in the open, underground spaces or pores, of soil and rock**  media type="file" key="Groundwater.3gp" width="300" height="300"

  **__Porosity__** is the measure of spaces in a material Porosity is measured by the volume (ml) of pore spaces/volume (ml) of sediment **__Permeability__** is the measure of the ability of a material to allow fluids to pass through

 //**So what's the difference between Porosity and Permeability?**//

Remember this: __**Percolation**__ is the downward movement and filtering of water through the holes of the ground as it enters the soil during infiltration Ground water is found in**//...//**

confined (kept within the bounds of something) or unconfined bodies of earth material that have the ability to hold and transmit water

**Unconfined (open) aquifers** are "connected" to the surface above.  **Confined (closed) aquifers** are sandwiched in between dense impermeable layers of earth material



- The upper portion of the aquifer is called the __**zone of aeration**__- the pores in this area are partially filled with water and the rest air - The lower portion of the aquifer is called the __**zone of saturation**__- the pores in this area are completely filled with water
