Additionally, through the use of a new dye-enhanced LIF technique, standard LIF tooling is now used to detect dye-labelled DNAPL chlorinated solvents. Direct push logging of the NAPL’s inherent fluorescence with depth provides rapid and reliable identification and delineation of NAPL. Multiple LIF logs completed at NAPL release sites provide a relatively non-subjective basis for a detailed NAPL conceptual site model (CSM).

Three LIF systems have been developed by Dakota Technologies to identify the presence, nature and extent of LNAPL and DNAPL at contaminated sites: Ultra-Violet Optical Screening Tool (UVOST®) for Petroleum, Oil, and Lubricants (POLs); Tar-Specific Optical Screening Tool (TarGOST®) for Coal Tars, Heavy Crudes, Creosotes; and Dye-Enhanced Laser Induced Fluorescence (DyeLIFTM) for DNAPL chlorinated solvents. All three LIF technologies collect and record data in-situ at high resolution, obtaining continuous readings while being advanced into the subsurface at a rate of approximately 2 cm/second. The result is a continuous data set with no data gaps such as those that are often experienced with traditional sampling methods due to poor sample recovery.
