Types of Springs

• A spring is a the natural discharge from an
  aquifer through a naturally occurring opening in
  the ground.  Springs can be divided into two
  major categories by the type of sediment that
  they come out of.  The first type is called a non
  artesian  or "water table" spring.  This is
  formed when rain seeps through the sandy top
  layer of the ground until it reaches the
  impermeable aquiclude.  The water will then build
  up until it runs down the gradient of the land on
  top of the aquiclude until it reaches a bluff or
  an outcropping, where it will flow out.  These
  type of spring do not usually produce much volume
  in discharge.

Artesian Springs

• The other type of spring is an artesian spring. 
  An artesian spring is formed when water is
  confined in the aquifer under the impermeable
  aquiclude until sufficient pressure causes the
  water to flow out of a natural opening.  Most of
  the springs in Florida, especially the high flow
  ones are Artesian Springs.
