Abstract:

An Enhanced Preliminary Assessment was conducted at the Bennett Army National Guard Facility Bennett ANGF, which is planned for inclusion in the Base Closure Program. Bennett ANGF is a 242-acre facility located approximately 20 miles east of Denver, Colorado, in a rural section of Arapahoe County. Bennett ANGF is located in what was the southeastern corner of the old Lowry Air Force Bombing Range. During the early 1960s, the property was the site of an operational underground Titan ICBM complex. Since 1975 the surface of the property has been used for field exercises by units in the Colorado Army National Guard CoARGN. No environmentally significant operations ESOs that would require immediate action were observed during the site visit on 17 October 1989 or during the follow-up interviews. Soil samples are recommended for the five above ground ESOs the Sewage Stabilization Pond and Runoff Trench, Chemical Waste Clarifier, Ordnance, and Potential Waste Disposal Areas. Four monitoring wells are recommended near the perimeter of the facility. The objective of the soil samples and the monitoring wells is to detect possible contamination from past releases. Since the underground Titan ICBM complex could not be entered, specific sampling recommendations are not possible. The next stage of activity should be a thorough visual inspection of the entire complex.
