Abstract

Knowledge of the properties of the Biscayne Aquifer is critical to the understanding of groundwater solute transport problems that affect the Everglades region. To add to our knowledge of the aquifer, geologic logging of cores and hydraulic conductivity measurements were performed in 18 fullypenetrating wells using an electromagnetic borehole flowmeter. Corelogs, ambient flow profiles, and hydraulic conductivity (K) values measured in the study site indicate that the Biscayne Aquifer has a hydraulic conductivity with a geometric mean of 0.18 meter/second and a variance of 2.5 , and can be divided into two distinct layers: the Upper Biscayne Aquifer and the Lower Biscayne Aquifer, which are separated by a 33-centimeter hard limestone layer. The hydraulic conductivity of the Upper Biscayne aquifer has a geometric mean of 0.29 meter/second and a variance of 1.9, whereas the Lower Biscayne Aquifer has a geometric mean of 0.056 meter/second and a variance of 2.1. The best estimate of longitudinal macrodispersivity for the full aquifer is 0.93 m, while the Upper and Lower Biscayne Aquifers show values of 0.97 and 0.20 m, respectively.
