| Description: | Technical Report Abstract: Five 1-hectare UXO/landmine test sites were established at Fort A. P. Hill, Virginia (two sites); Fort Carson, Colorado (2 sites); and Jefferson Proving Ground (JPG), Indiana (1 site). The sites were characterized to document them for the purpose of comparison with other UXO/landmine test sites and to provide presite disturbance assessments disturbance of site heterogeneity and the presence of buried cultural features. The investigations included measurements and surveys to determine geological, geophysical, and environmental parameters or properties and their variation with depth, lateral dimension, and time. The criteria used for choosing the geographical location of a site are predominant soil type and average yearly precipitation. Fort A. P. Hill is located in a humid region and has a sandy soil, whereas Fort Carson is considered semiarid and has both sandy and clayey soils. Jefferson Proving Ground is also classified as a humid region, but its soil is generally described as clayey. General results of the site characterizations were available to contractors for assessment and planning purposes prior to conducting the "background clutter data collection" geophysical surveys. At all sites, no trends in the magnetic field are observed across the sites. The sites at Fort Carson and Jefferson Proving Ground did show heterogeneity in the bulk electrical conductivity within the upper 4 to 5 m. The level of cultural background or clutter is minimal at the Fort Carson and JPG locations. The sites at Fort A. P. Hill have numerous anomalous features indicative of buried cultural features. |
