The site characterization and analysis cone = penetrometer system=20 (SCAPS), equipped with real-time fluorophore detection capabilities, was = used to=20 delineate subsurface contaminant releases in an area where plating shop = waste=20 was temporarily stored. Records indicated that various nonaqueous phase = liquids=20 (NAPLs) were released at the site. The investigators advanced the SCAPS=20 laser-induced fluorescence (LIF) sensor to depths beneath the water = table of the=20 principal water-bearing zone. The water table was located approximately = 6 feet=20 (1.8 m) below ground surface (bgs) across the site. Fluorescence, = attributed to=20 fuel compounds commingled with chlorinated solvents, was observed at = depths=20 ranging from 4.0 to 11.5 feet (1.2 to 3.5 m) bgs. Fluorescence, = attributed to=20 naturally occurring organic materials (by process of elimination and = spectral=20 characteristics) commingled with chlorinated solvent constituents, was = observed=20 at depths ranging from approximately 13 to 40 feet (4.0 to 12.2 m) bgs.=20 Fluorescence responses from compounds confirmed to be commingled with=20 chlorinated solvents indicates that the SCAPS fluorophore detection = system is=20 capable of indirectly delineating vadose zone and subaqueous chlorinated = solvents and other dense nonaqueous phase liquids (DNAPLs) at = contaminant=20 release sites. This confirmation effort represents the first documented = account=20 of the successful application of LIF to identify a mixed DNAPL/LNAPL = source=20 zone.
