Potentiometric maps of the water-table aquifer in the spring and fall of 1993 in the industrial area northwest of Delaware City, Delaware, are presented. The maps are based on continuously recorded ground-water-level data collected at eight wells screened in the water-table aquifer from October 15, 1993 through November 8, 1994. These data are presented on a 33" by 44" plate. The U.S. Army Corps of Engineers collected the synoptic water-level data used to construct contours of the potentiometric surface in the water-table aquifer. The U.S. Geological Survey collected the continuously recorded ground- water-level data.
