Dakota Technologies Offers UVOST® for Detecting Petroleum Spills in the Subsurface

UVOST® allows rapid screening of most petroleum-based light non-aqueous phase liquids (LNAPLs).

Fargo, ND (PRWEB) May 04, 2012

Dakota Technologies introduces the UVOST®, a direct-push delivered sensor that allows rapid screening of most petroleum-based light non-aqueous phase liquids (LNAPLs). This tool uses laser-induced fluorescence (LIF) technology to immediately detect sub-surface contamination without having to draw samples or wait for lab results.

The UVOST responds exclusively to source term NAPL, free of interference from dissolved phase hydrocarbons, and it is ideal for detecting fuels, lubricants, and crude oils. The system is designed for use with all direct-push platforms such as Geoprobe®, AMS PowerProbe®, and cone penetrometers.

When deployed, the UVOST´s probe uses ultra-violet laser light and a sapphire-windowed sensor to detect the polycyclic aromatic hydrocarbons (PAHs) that are found in petroleum LNAPL. As the probe is driven into the ground, the LNAPL´s fluorescence signal is sent through a fiber-optic cable to a detector and logged by a laptop computer, so results can be seen in real time, and on-site personnel can begin determining an ideal location for the next probing location. In a typical day 250 to 500 feet of continuous logging can be performed.

For each hole the UVOST generates a detailed, colorized log that shows the presence of PAH LNAPL versus depth. The high-resolution electronic logs can be easily incorporated into three-dimensional conceptual site models, which are used to help estimate costs and create a plan for removal of the contaminants.

Dakota offers the UVOST strictly in product form, and the service is only available through certified owners. The UVOST comes with a one-year warranty, and UVOST purchasers are required to undergo a rigorous three-day training session.

Other products and services from Dakota Technologies include the Dart and TarGOST for screening coal tar and creosote DNAPLs, as well as the SCOST for logging Munsell soil color with direct-push platforms.

Since 1993, Dakota Technologies, Inc. has developed and commercialized laser-induced fluorescence systems for the rapid characterization of sub-surface contaminants such as fuel, oil and coal tar.
