Description
The water-absorbing layers of rock underlying south Florida divide into three layers. The Biscayne Aquifer is closest to the surface and because of this it directly interacts with natural and man-made bodies of surface water, such as streams, lakes, canals and reservoirs. The ground water and the aquifer currently are managed as an integrated water system.
Because the top part of the Biscayne aquifer is the water table, this aquifer is known as an unconfined aquifer. Since it merges with the floor of Biscayne Bay and with the Atlantic Ocean, it is also a coastal aquifer. Both of these factors contribute to its potential contamination. Lowered water tables, primarily from over-pumping, could allow salt water intrusion without man-made interventions such as dam-like structures that control fresh and salt water levels in canals. Because the aquifer is so close to the surface, it is extremely vulnerable to surface contaminants.

Famous quotes containing the word description:
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
