High Resolution Site Characterization tools – UVOST

 

 

uvost-example-960

The UVOST® technology efficiently delineates petroleum, oil, and lubricant (POL) contaminants in the subsurface. All the usual forms of POLs, including; gasoline, diesel fuel, jet fuel, and hydraulic fluids, can be detected via the fluorescence response of their polycyclic aromatic hydrocarbon (PAH) constituents. This response provides both qualitative and quantitative information on the petroleum products identified in the subsurface, enabling the identification of product type and relative concentration data. The TarGOST® performs the same function for heavier NAPLs with high PAH content – Coal Tar, Creosote, etc.

UVOST’s LIF technique, in conjunction with direct push deployment, yields a detailed three-dimensional map of the NAPL distribution in real-time – offering rapid, adaptive site characterization capability as promoted by U.S. EPA’s TRIAD approach.

The Minnesota Pollution Control Agency (MPCA) Petroleum Remediation Program (PRP) routinely uses laser-induced fluorescence (LIF) data to target petroleum light non-aqueous phase liquids (LNAPLs) when remediation is necessary. Paul Stock, Hydrogeologist with the MPCA PRP, authored an excellent article describing the LIF technology, uses and limitations in the June 2011 LUSTLine, Bulletin 68, beginning on page 13.
