COLUMBIA Technologies Supports the Sixth International Seminar on Environmental Characterization and Remediation of Sites Impacted by Hydrocarbons – 2012 in Mexico City

September 15th, 2012

COLUMBIA Technologies recently supported the Sixth International Seminar on Environmental Characterization and Remediation of Sites Impacted by Hydrocarbons – 2012 in Mexico City, Mexico. The seminar was hosted by Rede Latino Americana de Prevenção e Gestão de Sítios (ReLASC) in partnership with PEMEX Refinery and Ecoterra Servicios Ambientales.

On Friday, September 14, COLUMBIA presented Rapid High Resolution Site Characterization Using Direct Sensing Technologies. With local teaming partner, International Products and Organic Solutions (IPOS) on Saturday, September 15, COLUMBIA provided a hands-on demonstration displaying how these advanced tools can be applied to a wide range of contaminated sites.

Below are photos from the presentation and demonstration. Read the rest of this entry »

John H. Sohl III is founder of Columbia Technologies, a Maryland company that maps underground pollution from large manufacturing facilities, oil terminals, pipelines and military bases. The company is a client of the Baltimore Export Assistance Center.

Barry:  How do you map underground pollution?

Sohl:  Mapping involves deployment of sensor technologies that track leakage and migration of pollutants.  Following analysis by our technicians, customers can make decisions on risk assessment, disposition of the property and proper cleanup actions.  Read the rest of this entry »

Five Steps to Developing Weighted Lines of Evidence During Site Characterization

May 30th, 2012

One of the most critical points to remember when developing a site closure work plan is that it simply costs too much to assess, remediate, and make decisions on information that is incomplete, inaccurate, and too late. Traditional approaches to characterizing subsurface conditions by drilling, soil sampling, and monitoring wells screened over large intervals are too incomplete to accurately deal with site heteregoneity.

Therefore, a high resolution site characterization approach is a more attractive option as it enables projects to move forward with remediation focused activities such as corrective action, free product recovery efforts, and site closure.

Let’s face it, the heterogeneity geology of a site is going to impact the migration of subsurface contamination opposed to the age old myth that it always follows the direction of groundwater. Introduction of the Hydraulic Profiling Tool (HPT) for site investigation and remediation efforts supports contaminant mapping activities to provide a greater understanding of subsurface conditions. By measuring direct pressure response, HPT develops weighted lines of evidence indicating the tight (or loose) grains and low (or high) flow zones in order to determine the migration pathways, remediation injection regions, and placements for monitoring wells. With an integrated Soil Electrical Conductivity (EC) array this tool also defines zones of lower conductivity which allows for the movement of contaminants into the subsurface.
