• FORMER NANSEMOND ORDNANCE DEPOT, SUFFOLK (CITY) County, VA

Stage of Clean-up: Study Underway

Conditions at Proposal (January 19, 1999): The Former Nanse mond Ordnance Depot (NOD) is located on a former 975-acre U.S. mi litary facility at the northwestern end of State Route 135. The former NOD property was bordered to the west by the Nansemond Riv er, to the north by the James River (Hampton Roads), to the east by Streeter Creek, and to the south by commercial and light indus trial areas. Portions of the former NOD property are currently o ccupied by the Portsmouth Campus of Tidewater Community College ( TCC), General Electric Company, and Dominion Lands, Inc. EPA's S uperfund Program currently maintains an interest in releases from the seven waste sources listed below and in other selected areas of concern. The facility was obtained by the United States Army between 1917 and 1929, and was known as Pig Point Ordnance Depot until 19 29. During World Wars I and II and the intervening years, the de pot was used for various activities related to the preparation, p rocessing, storage, shipment, salvage, reconditioning, and dispos al of ammunition. It was apparently used after World War II in d emobilization, including dumping explosives, ammunition, and chem icals. The depot was operated by the Navy as the Marine Corps Suppl y Forwarding Annex from 1950 to 1960, when it was declared excess . The Beazley Foundation operated a private boys military academ y at the site from 1960 to 1968.  More...

In the Spring of 1987, it was found that bulk explosives, munitions, shells, and other ordnance items, both spent and unexploded, had been disposed of by the Department of Defense (DoD) in a 2- to 3-acre area adjacent to College Drive on TCC property. A confirmation study of this area, hereafter referred to as the "TCC Removal Area", was conducted in June and July, 1987, by the U.S. Army Corps of Engineers (USACE) under the Defense Environmental Restoration Program. This study showed the presence of ordnance and ordnance-related materials, including 19 live munitions, numerous grenades, and a slab of crystalline 2,4,6-TRINITROTOLUENE (TNT) estimated to weigh several tons. Between November, 1988, and February, 1989, the following materials were removed from the Removal Area: 4,400 pounds of boosters, 260 pounds of bulk explosives, 1,360 pounds of munitions/miscellaneous ordnance, and 30,275 pounds of contaminated soil. USACE conducted additional field work in the removal area between November, 1989, and February, 1991, as part of a Remedial Investigation and Feasibility Study (RI/FS).  More...
