Abstract:

An enhanced Preliminary Assessment was conducted at the Defense Mapping Agency DMA site in Herndon, Virginia which is planned for inclusion in the Base Closure Program. The facility is located on approximately 12 acres of land in northern Virginia. Initially constructed as a NIKE missile Integrated Fire Control Area, the site is now administered by the U.S. Army Corps of Engineers and permitted to DMA. At the site DMA maintains activities that support field personnel performing geodetic mapping operations. During the survey no conditions requiring immediate action were discovered. Six environmentally significant operations ESOs were identified and recommendations are made for sampling at four of the ESOs. The specific items to be evaluated include Collecting groundwater samples in the wells at each of the underground storage tanks to an analyzing for total petroleum hydrocarbons TPH, Collecting 3-6 soil samples at the location of the former paintoil storage shed and analyzing for TPH and metals, Obtaining air samples at 4 locations in the facility and analyzing for asbestos fibers, Obtaining 2 soil borings in the area of the septic field and installing a monitoring well in one of the boring holes, and analyzing the soil collected and a sample from the bottom of the well for volatile organic compounds. The recommendations for sampling are based on information gathered concerning past spills and material storage and handling procedures. Observations made during the site visit indicate the present operations have minimal impact on human and environmental receptors.
