Map of florida aquifers. However in the extreme western panhandle and in south florida the fas is either too deep or contains water. Although groundwater development captures some of the water that would naturally discharge from the system and alters the potentiometric surface boundaries of the major groundwater basins delineated from the estimated predevelopment map. The floridan aquifer system fas which underlies all of florida is the main source of potable groundwater for much of the state. Framework gis data available digital surfaces and thicknesses of selected hydrogeologic units of the floridan aquifer system were developed to define an updated hydrogeologic framework as part of the u s.
Water quality in the. Map of the principal aquifers of the united states. Aquifers can be thought of as vast underground porous rocks that hold water and allow water to move through the holes within the rock.

The surficial green sand and gravel red and biscayne aquifer purple pink lie on top of the floridan aquifer. Aquifers are classified as either unconfined semi confined or confined depending on the physical conditions under which the water is contained in an aquifer s rocks. The map layer was developed as part of the effort to produce the series ground water atlas of the united states.
