ST HWY 94 2 MI S US 40
The Weldon Spring Former Army Ordnance Works site is located in St. Charles County, Missouri about 30 miles west of St. Louis and about 14 miles southwest of the City of St. Charles. It is bisected by State Highway 94, bounded on much of the north by U.S. Highway 40-61, and bounded on much of the south by the Missouri River. The area of the Ordnance Works site during production was 17,232 acres. During its operation, the site produced explosives including trinitrotoluene (TNT) and dinitrotoluene (DNT) for the U.S. Armed Services. A series of land transfers left the Army with 1,655 acres, which it has operated since 1959 for the Army Reserve as the Weldon Spring Training Area. Contaminated areas are spread throughout the 17,000 acres of the site, with the greatest concentration in the Training Area. Some of the transferred land that covered two small areas of the original Ordnance Works area now are owned by the U.S. Department of Energy (DOE) and listed on the National Priorities List as Weldon Spring Quarry/Plant/Pits site. Investigations have identified a number of potentially contaminated areas, including seven unlined lagoons where TNT wastewater was stored, TNT production lines, two DNT production lines, drainage ditches below TNT production lines, and eight areas where explosive wastes were burned. Approximately 5,000 people live within 3 miles of the site, and approximately 70,000 people obtain drinking water from St. Charles County wells located within 3 miles of the hazardous substances at the site. Surface water in the area flows either to the Mississippi River watershed to the north or the Missouri River watershed to the south. Surface waters located within 3 miles are used for recreational activities.
