water actually began as last year's rain falling many miles away in another
higher part of Florida.
Going With the Flow
The Florida Peninsula has a central, higher ridge, and then it slopes
or dips gradually from that central ridge down to the coast. Rainwater,
falling on these high areas, sinks into the Floridan Aquifer through cracks
in a "confining" or watertight layer. Pressure then builds in
the Aquifer as rains continue, and the large mass of water flows slowly
downhill but still underground. In openings at lower elevations, such
as Blue Spring, water is eventually driven out of the ground by pressure
that built up in the Aquifer below.

the "Boil"' pushes out 104 million gallons of water per
day, then how many gallons are pushed out?
in two hours? (Answer = 8,666,666.67 gallons in two hours)
b) in two minutes? (Answer = 144,444.45 gallons in two minutes)
c) in 30 seconds? (Answer = 36,111.11 gallons in thirty
d) in 10 days? (Answer = 1,040,000,000 gallons in ten days)
e) For comparison, estimated water use to do common things at home:
-20 gallons for a bath
-30 gallons for a shower
-40 gallons for a load of laundry
-15 gallons for your dishwasher
-60 gallons to wash your car
fish are seen here because of the low oxygen content in the water and
the absence of aquatic plants. However, after flowing about 100 yards
above ground oxygen is absorbed into the water and many kinds of fish
begin to appear.
