Miami Geological Society Publications The Effects of Diagenesis on the Hydrology of the Surficial Aquifer, Broward County, FloridaBy Joseph F. Whitley
The Surficial Aquifer system of southeastern Florida supplies drinking water as a sole-source aquifer in Dade, Broward, and southernmost Palm Beach County. The aquifer consists primarily of marine to fresh water carbonates of Plio-Pleistocene age. This study shows
the relationships between diagenesis and the hydrology of the Surficial
Aquifer in Broward County. Lithology and trace element concentrations were
employed to determine zones of relatively high diagenesis. These zones are
plotted on lithologic cross-sections and compared to geohydrologic cross-sections
by Fish (1987). Zones of low hydraulic conductance (100 feet per day or
less) correlate well with zones of high diagenetic trace element signatures.
Lithologic and geochemical techniques of investigation used in this study
can be helpful in the mapping of hydraulic conductance in similar carbonate
terrains.

reports and documents have been scanned from the original hard-copy materials
and are made available on the internet in both HTML and PDF formats. Because
these are scanned documents, we are unable to provide fully-accessible versions
of these reports. If you cannot fully access the information in these documents,
