UVOST® 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. The fluorescence signal is directly proportional to concentration.

The BEAM is designed to determine the amount of Dissolved Organic Matter (DOM) in ballast water by means of measuring fluorescence in two-channels.

Key features of the BEAM include:

• It provides an indication whether open ocean exchange occurred
• The method of sampling is easy and convenient
• The approach is cost effective and viable on a global scale

The ARSLID® monitor is a portable instrument that directly detects total aromatic concentrations in real-time. ARSLID® is based on resonance enhanced laser ionization, which greatly increases both the specificity and sensitivity for aromatic compounds compared to conventional photoionization detectors (PIDs).

Interested to know what's coming from Dakota in the future?  We're developing...

• Dakota's soil color system to log Munsell color values versus depth.
  
• Darts a quick and inexpensive screen for PAHs in sediments and similar soft soils.
  
• TREW™, the Twin Reservoir Equilibrated Water sampler for subsurface passive monitoring of conventional wells.
