1/15/2008 Site Characterization Report Approved Thirty-seven soil borings were drilled at the site. Field screening was conducted with a photoionization detector and soil samples were collected from 23 of these borings. The highest contaminant concentrations were detected in a sample collected to characterize a soil stain caused by a leaking 55-gallon drum at the north corner of the armory. Surface soil at this location had 2,400 mg/Kg GRO, 0.66 mg/Kg benzene, 6,600 mg/Kg DRO, and 20,000 mg/Kg RRO. Other areas with elevated hydrocarbon concentrations were located at the south and east corners of the armory, where spills from the 3,000-gallon AST and Jet A1 fuel drums had previously been documented. Groundwater sampling was conducted from three temporary well points. Lab results from a well point in the area affected by the 3,000-gallon AST showed that the groundwater had DRO concentrations at 1.9 mg/L. Lab results from a downgradient well across the road showed groundwater with DRO concentrations of 1.3 mg/L. The groundwater may meet the requirements for an exemption under 18 AAC 75.350.
