Ground-Water Flow in the Surficial Aquifer System and Potential Movement ofContaminants from Selected Waste-Disposal Sites at Cecil Field Naval Air Station, Jacksonville, Florida

摘要

This report presents the results of a study to analyze ground-water flow in thesurficial aquifer system in a 36-sq mi area that includes most of the Cecil Field NAS. The report includes ground-water-level and surface-water-discharge data, a description of the hydrogeologic framework, and an estimate of the water budget and base flow in the study area. Simulation results are presented from a calibrated, three-dimensional finite-difference, ground-water flow model of the 36-sq mi area. A regional and cross-sectional model are presented to support the lateral boundaries of the study area and the approach used for model calibration, respectively. Estimates of groundwater movement from existing and potential sites of contamination to their discharge points by way of particle tracking are presented.
