Abstract:

Between December 1993 and March 1994, 27 wells were installed at 12 sites near the J4 test cell at Arnold Engineering Development Center AEDC in Coffee County, Tennessee. The wells ranged from 28 to 289 feet deep and were installed to provide information on subsurface lithology, aquifer characteristics, ground-water levels, and ground-water quality. This information will be used to help understand the effects of dewatering operations at the J4 test cell on the local ground-water-flow system. The 54 test cell, extending approximately 250 feet below land surface, is used in the testing of rocket motors. Ground water must be pumped continuously from around the test cell to keep it structurally intact. The amount of water discharged from the J4 test cell was monitored to estimate the average rate of ground-water withdrawal at the 54 test cell. The purpose of this report is to present well-construction details and water-quality sampling results for the J4 hydrogeologic study. Well-construction details for the 27 wells installed by the U.S. Geological Survey are presented. Water-quality analyses are reported for the 54 test cell ground-water discharge, 26 wells drilled for this study, and 9 pre-existing wells. Hydrographs are presented for 14 wells for the period July 1994 through June 1995. Discharge data from the 54 test cell are presented for the period October 1990 through September 1995. Rainfall data are presented for this same period.
