The Weldon Spring Training Area at Weldon Spring, St. Charles County, Missouri, is a portion of the former Weldon Spring Ordnance Works (WSOW) where trinitrotoluene (TNT) and dinitrotoluene (DNT) were manufactured during World War II. Nitroaromatic contaminants remain on the Weldon Spring Training Area (WSTA) despite several attempts to decontaminate the property since closure of the ordnance works in 1945. Much of the former WSOW property has been added to the US Environmental Protection Agency's National Priorities List of Superfund sites. As a result, the US Army Corps of Engineers has initiated further efforts to decontaminate and remediate the property. One of the initial steps of an environmental remediation action is characterization of the geologic setting at the site. Characterization and detailed mapping of surficial material units define the soil types and their origin. This information is critical to decision-making during the clean-up, and assists in defining potential contaminant migration pathways. In 1991, the US Army Corps of Engineers, Kansas city District requested the Missouri Department of Natural Resources, Division of Geology and Land Survey (MDNR-DGLS) to identify the surficial material units in the approximately 1,700-acre WSTA site and to define their engineering properties. The 12-month study included exploratory trenching and soil borings to characterize the surficial material units, laboratory testing to determine engineering properties of each surficial material unit, and detailed mapping and cross sections of the surficial material units utilizing the MDNR-DGLS Geographic Information System (GIS).
