Field trials of the site characterization and analysis penetrometer system at the Savannah River Site (SRS). Final report
The Site Characterization and Analysis Penetrometer System (SCAPS), developed at the U.S. Army Engineer Waterways Experiment Station (WES), was deployed to demonstrate its capabilities to detect and delineate various subsurface contaminants at the Department of Energy's (DOE's) Savannah River Site (SRS) near Aiken, South Carolina. The Westinghouse Savannah River Company is under contract to DOE for management and operation of the SRS. The SCAPS experiments were conducted as part of a joint Department of Defense (DOD)/DOE research project on the application of cone penetrometer-based technology for the detection and delineation of contaminated soils. Two SCAPS devices combining unique contaminant-screening processes (fluorometry and resistivity) with conventional electric friction cone penetrometer test (CPT) technology were used. The SCAPS fluorometer probe is designed to illuminate soil in contact with the side of the CPT with pulsed laser light as the CPT is pushed into the ground. The laser light is transmitted through one of two silicon fiber optic links downhole to pass through a small sapphire window in the side of the instrument. Fluorescent light energy induced by the laser in the soil is returned through a second, passive fiber to spectrophotometry equipment at the surface. The SCAPS fluorometer probe detected and mapped hydrocarbon fuel contaminants in soil at two SRS facilities with concentrations as low as 200 ppm. Hydrocarbon contaminant concentrations measured at one site with the fluorometer probe were visualized in three dimensions using specialized computer graphics software.
