6.5.1. 317/319/ENE Area Characterization




6.5.1.1. RCRA Facility Investigation




Field activities for the RFI were conducted in the 317/319/ENE areas between December 1994 and September 1995. The field program resulted in the installation of 19 groundwater monitoring wells and the completion of 31 soil borings. A total of 83 soil samples and 30 groundwater samples were taken and submitted for chemical analysis. Thirty-nine soil samples were taken for geotechnical testing. Soil gas measurements and additional soil samples were taken during a shallow soil survey consisting of 90 split spoon probes.

In addition to the soil borings and well installation work, a sampling program for surface soil, surface water, and sediment was also completed. A total of 24 surface soil samples were collected from throughout the project area. Surface water and sediment samples were collected at 11 locations in four separate storm drainage ditches that remove storm water from the project area. The locations of the monitoring wells and soil borings are shown in Figure 6.2.
