COLUMBIA Technologies’ state-of-the-art equipment and rapid 3D visualizations combined with historical data completed a site assessment so efficiently that the original project work scope was reduced by 50%.
On this recently completed project, a major energy company required state clearance from regulators prior to advancing their expansion plans at an active petroleum refinery facility in western North Dakota. Read the rest of this entry »
Sample LIF UVOST® Log
During a recent site characterization in Hawaii using LIF/UVOST® technology COLUMBIA Technologies encountered relatively low levels of petroleum contamination hidden in an usually high background response. This resulted due to the presence of naturally occurring fluorescence materials (likely calcareous sands) in the subsurface at the site. This elevated background fluctuated in response intensity from log to log and often within a single log, making it more difficult to accurately identify residual petroleum contamination responses in the subsurface.
