LIF - UVOST & TarGOST

UVOST

(Ultraviolet optical screening tool)
Used to detect almost any PAH containing NAPL

• Petroleum, Oils and Lubricants (POL)
• Gasoline
• Diesel
• Jet (Kerosene)
• Motor Oil
• Cutting Fluids
• Hydraulic Fluid

TarGOST

• Coal Tar (MGP Waste)
• Creosote/Pentachlorophenol
  (Wood treating)

Types of Sites LIF is used on:

• Leaking underground storage tanks
• Pipelines
• Refineries
• Fueling Areas
• Fire-training facilities
• Automobile service locations (hydraulic fluid, POLs)
• Surface Spills
• Lagoons - waste ponds/tank bottoms
• Former MGP sites
• Wood treating sites

UVOST & TarGOST Benefits

1. Daily productivity of 300-500 feet across 10-20 locations.
2. Electronic and graphic deliverables.
3. Approximately 1 inch continuous data resolution.
4. Fluorescense signal is directly proportional to concentration.
5. Typical detection limit of <100 ppm.
6. Waveforms offer product identification/verification as well as rejection of non-contaminant fluorescence such as mineral, peat and other minor interferences.
7. Color-coded logs for immediate qualitative information "at a glance"
8. Logs printed immediately after boring completed and can be emailed or inputted into 3D graphics so real-time decisions can be made
9. LIF instruments do not respond to chlorinated solvent contaminants such as TCE and PCE or to lower dissolved phase (aqueous) contaminants such as BTEX. 

For chlorinated solvents and low dissolved phase delineation please see the information on the MIP (membrane interface probe)
