Vertical Profiling: A Comprehensive and Holistic Approach to Site Characterization

January 13th, 2011

From assessing hundreds of subsurface pollution investigations for our diverse client base, we’ve come to the conclusion that in order to conduct an effective site characterization and move forward with remediation design plans, one must have a comprehensive knowledge of their sites’ vertical profile. We define a complete vertical profiling project by understanding the hydro-stratigraphy in addition to the contaminant distribution in order to make cost-effective and practical remediation designs and environmental decisions.

SmartData Solutions® helps reduce project work scope by 50%

September 14th, 2010

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

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.
