Paper Abstract

Laser induced fluorescence (LIF) is a powerful technique for in-situ detection of subsurface contamination due to petroleum products. This paper describes the Site Characterization and Analysis Penetrometer System (SCAPS) LIF sensor which combines an LIF spectroscopic system with a cone penetrometer truck, and presents field results from a recent site characterization of a diesel fuel contaminated site. In addition to the LIF sensor measurements performed at the site, 130 soil samples were collected by hollow stem auger with split-spoon sampling and analyzed by EPA approved laboratory methods to validate the fluorescence sensor. The LIF sensor showed 96% agreement with the laboratory analysis on a detect/non- detect basis. Quantitative comparison of the fluorescence and analytical data show a strong correlation, suggesting that the fluorescence sensor may be capable of quantifying the contaminant concentration given a small number of soil samples for calibration.
