In August 1994, a demonstration of geoprobe- and cone penetrometer-mounted sensor technologies took place to evaluate their effectiveness in sampling and analyzing the physical and chemical characteristics of subsurface soil at hazardous waste sites. Technology effectiveness was evaluated by comparing each technology`s results to the results obtained using conventional reference methods. The demonstration was developed under the Environmental Protection Agency`s (EPA) Superfund Innovative Technology Evaluation Program. Three technologies were evaluated: the Rapid Optical Screening Tool (ROST{trademark}) marketed by Loral Corporation, the Site Characterization and Analysis Penetrometer System (SCAPS) Laser Induced Fluorescence (LIF) and Cone Penetrometer (CP) Sensors developed by the Tri-Services (Army, Navy, and Air Force), and the conductivity sensor developed by Geoprobe Systems. These technologies were designed to provide rapid sampling and real-time, relatively low cost analysis of the physical and chemical characteristics of subsurface soil to quickly distinguish contaminated areas from noncontaminated areas. This paper focuses on the capabilities and applications of the ROST{trademark} and SCAPS LIF and CP sensors technologies, and compares how closely each technology`s data mirrors the reference method data. The Geoprobe{reg_sign} conductivity sensor is not addressed because the data it generated during the demonstration is still under evaluation.
