Project Overview
The Laser Induced Fluorescence (LIF) Probe can be deployed by cone penetrometer for real-time, depth discrete delineation of contaminants that fluoresce under ultraviolet illumination, such as petroleum oils and lubricants (POL) and co-contaminants in Dense Non-Aqueous Phase Liquids (DNAPLs). Several mature implementations of this technology exist, differing in illumination source and wavelengths and in the methods used to analyze the time and/or frequency spectra of the emitted fluorescence. This technology is one component of the DNAPL Toolbox (TechID 237).
