Hydrogeologic evaluation of a sand and gravel aquifer contaminated by wood-preserving compounds, Pensacola, Florida
The sand and gravel aquifer in southern Escambia County, Florida, is a typical surficial aquifer composed of quartz sands and gravels interbedded locally with silts and clays. Because creosote is the most extensively used industrial preservative in the US, an abandoned wood-treatment plant near Pensacola was chosen for investigation. This report describes the hydrogeology and groundwater flow system of the sand and gravel aquifer near the plant. A three-dimensional simulation of groundwater flow in the aquifer was evaluated under steady-state conditions. The model was calibrated on the basis of observed water levels from January 1986. Calibration criteria included reproducing all water levels within the accuracy of the data. Applications of the results of the calibrated flow model in evaluation of solute transport may require further discretization of the contaminated area, including more sublayers, than were needed for calibration of the groundwater flow system itself. 32 refs., 44 figs., 4 tabs.
