Rapid characterization of a large volume of groundwater related to a historical fuel spill was performed using a combination of commercially available technologies. The three primary technologies used include (1) a drive-point sampling device (i.e., Geoprobe{reg_sign}); (2) a mobile on-site field laboratory; and (3) a Global Positioning System (GPS). The drive-point sampling device was used to advance 2.5-cm outer dia carbon steel rods and an end rod containing a retractable 61 cm well screen. The rods and screen were advanced to depths of up to 36.5 m below ground surface and acted as a temporary well. Groundwater samples were collected from the screened interval and immediately analyzed in the on-site field laboratory for total petroleum hydrocarbons, benzene, toluene, ethylbenzene, xylenes, and carbon dioxide. Each sample location was determined using the GPS. After the screening phase of the project, two small-diameter permanent wells were installed using drive-point technology. Advantages of combining these technologies in a single field effort include minimization of investigation-derived waste, minimization of formation disturbance, rapid generation of multilevel groundwater screening data to facilitate field decisions, and an overall cost savings when compared to the more conventional drill-rig/screened-auger/local fixed-base laboratory approach.
