Nine boreholes were advanced in the area of concern to depths ranging from 11 to 21 feet bgs. Based on field screening, soil samples were collected from two boreholes at depths from 8 to 9.5 feet bgs in the immediate area of the initial detections. These samples contained DRO up to 81.3 mg/kg, RRO up to 446 mg/kg, GRO up to 38.2 mg/kg, and benzene up to 4.0 mg/kg. | Bill O'Connell |
