Abstract

Naval Air Station Whiting Field is located near Milton, Florida and is one of the Navy's two primary pilot training bases. Commissioned in 1943, historic operations at Whiting Field generated industrial wastes that contaminated soil and the water-table aquifer. The Environmental Protection Agency placed Whiting Field on the Superfund program’s National Priorities List of contaminated sites in 1994. The U.S. Geological Survey was tasked with studying the contaminant migration and remediation processes at this site. A numerical model is under development to better define groundwater flow patterns, discharge to surface water, and the potential fate of contaminants. An initial model discretized the water-table aquifer into 5 layers, with the top layer between land surface and elevation -50 feet National Geodetic Vertical Datum of 1929 (NGVD29). However, with land surface ranging from 3.3 to 206.6 feet NGVD29, the top layer thickness is over 250 feet at highest land elevations. To more accurately simulate contaminant transport, refining the resolution in this top model layer is necessary.
