After 20 years in enviromental sampling and analysis we have come to believe in direct sensing as a means of providing the most rapid and comprehensive information about the distribution and composition of soil and groundwater contamination. Ever evolving, today’s direct sensing tools for remediation focused site characterization projects continue to add a greater range of high resolution information on subsurface conditions including hydrology, lithology and contaminant distribution to support environmental liability decision.

Although direct sensing approaches are used throughout the environmental industry supporting cleanup and closure efforts, there are still several myths associated in applying these methods to site investigation and remediation projects.

There are three basic assumptions or principles we have in mind when deploying high resolution direct sensing tools with as near real time decision-making information:

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.

Doug Barry is a Senior International Trade Specialist in the Trade Information Center, U.S. Commercial Service within the International Trade Administration. 

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.

Sohl:  I started the company about 15 years ago after doing similar work in the U.S. Navy.  I was always intrigued with the application of sensors and three-dimensional mapping of components, and that’s the approach we brought to the industry.  The world really is getting flat and many of our clients are global industries that have footprints both in the U.S. and North America as well as the globe.  So once we’ve established a good working relationship and reputation with those firms, they sought to bring us into other parts of the globe.

Barry:  So your initial market entry strategy was to piggyback on clients here in the U.S. and ride them into new markets.

COLUMBIA Technologies recently completed the Veteran Institute Procurement (VIP), a comprehensive training and certification program that helps veteran-owned businesses strengthen their ability to win government contracts and do business with both military and civilian agencies they once served in uniform.

On October 20, 2011, COLUMBIA Technologies was one of 45 businesses from 17 states to graduate from the National Center for the Veteran Institute for Procurement at the Bolger Center, a government-owned conference facility located in Potomac, MD. During the program’s graduation, John Sohl, CEO of COLUMBIA Technologies was presented with a congressional citation on behalf of U.S. House of Representatives Congressman, John P. Sarbanes.

 Most recently, the June 2011 issue of LUSTLine featured an article, "Where's the LNAPL? How about Using LIF to Find It?" written by Paul Stock of the Minnesota Pollution Control Agency (MPCA) Petroleum Remediation Program (PRP).

Paul's article provides an educational read on the ins and outs of LIF, the effectiveness of this LNAPL mapping tool, and Minnesota's experience in managing LNAPL risks.

Some key highlights include:

• How Minnesota's PRP routinely uses data from LIF probes to target petroleum LNAPL when remediation is necessary
• ITRC's LNAPL Team which has developed a set of excellent classroom training modules that lay out the latest understanding of LNAPL behavior using a multiple lines of evidence approach
• The importance that LNAPL data must be integrated with all available standard site data, including site history, present land use, geology, and soil and groundwater contamination to develop an LNAPL science-based site conceptual model (SCM)

 Throughout much of the approximately three-decade-old history of waste site cleanup, sub-surface site characterization has been something of a high-stakes gamble. You could install monitoring wells into the soil and groundwater, spending thousands of dollars per well while essentially guessing how best to develop a picture of where contamination has spread or where a groundwater plume is headed—and you could be wrong, prompting a costly revisiting of the site and possibly even lawsuits.

More recent history has seen the advent of high-resolution techniques that that have reduced the cost and improved the accuracy of sub-surface characterization. One company that has put those techniques to work at approximately 750 sites throughout its 10-year history is Columbia Technologies (Baltimore, MD), a provider of high-resolution direct sensing and mapping technologies such as the membrane interface probe (MIP), laser-induced fluorescence (LIF), the hydraulic profiling tool (HPT), a discrete groundwater profiler with on-site volatile organic compound (VOC) analysis, and associated data management tools for real-time information processing and visualization.

COLUMBIA Technologies CEO John Sohl looks back on the company’s experience at those 750 sites and sees three principles in play when it engages clients in today’s marketplace. First, “they want to define the issue, and not just produce data for data’s sake, and to keep regulators off their backs,” he says. Second, clients understand that better information leads to better decisions on cleanup and response. Third, “they’re saying, ‘I’d rather have an abundance of fairly close information and be approximately correct than be precisely wrong.’”

COLUMBIA Technologies has been recognized for their rapid expansion of their industry unique business model throughout North America with EBJ’s 2010 Business Achievement Award for New Practice Areas. In 2010, COLUMBIA Technologies extrapolated their “on call” business model into 29 states including Hawaii, increasing their total market penetration to 45 of 50 states; and into the provinces of Alberta and Ontario, Canada. Upcoming projects are in the planning stage for Mexico as well as Puerto Rico.

In 2010, COLUMBIA Technologies worked with 57 different clients throughout North America and Hawaii at over 100 project locations. They contracted with 10 out of 20, 15 out of 30, and 20 out of 40 from the Environmental Business International’s top rated environmental consulting and engineering firms on a broad range of commercial and military sites.“Our unique business model enables us to work with environmental, legal and property professionals throughout the United States and overseas while delivering cost-effective solutions to optimize site remediation” said John Sohl, Chief Executive Officer for COLUMBIA Technologies. “In previous years and certainly in 2010, we’ve proven that COLUMBIA is not limited to a specific geographic region and our primary focus is serving our clients on a nationwide scale.”

Dissolved phase TCE (trichloroethylene) was detected in the Millsboro, DE, water source during routine sampling of the community's water supply wells, and was traced to nearby township wells. The TCE, which was banned from public use in the 1970s, was detected at levels greater than the U.S. EPA's maximum contaminant level for public drinking water. Investigations completed by the Delaware Department of Natural Resources and Environmental Control – Site Investigation and Restoration Branch and by EA Engineering, in Sparks, MD, determined that the source of the TCE mass distribution was a former poultry vaccine manufacturing facility located less than 1,400 ft. from the public wells. TCE had been used as a heat transfer medium in a closed refrigeration system at the facility.

EA Engineering contracted with COLUMBIA Technologies, LLC, in Baltimore, MD, to conduct an investigation at the Millsboro public well site using the Direct Image^® Membrane Interface Probe and a Geoprobe^® 6620DT. The MIP data was used to characterize the subsurface soils in the vadose and saturated zones while delineating the lateral and vertical boundaries of contaminant in the soil and groundwater. "We used our SmartData Solutions^® and 3D graphics with the MIP data," said John Sohl, COLUMBIA Technologies CEO, "which enabled EA Engineering to refine the targeted depth of the contamination and determine accurate depth intervals to inject MFR. The information also allowed the remediation team to better target the TCE contamination by using less volumes of remediation materials and developing a more effective cleanup." SmartData Solutions^® is a real-time, rapid 3D visualizations and information delivery system developed by COLUMBIA Technologies.

 One of the companies in the new Maryland Clean Energy Incubator at the University of Maryland, Baltimore County is trying to make real estate development easier and faster.

Columbia Technologies, launched by two engineers in 1999, uses sensors to determine what kind of pollution is underneath a future or existing building site, turning weeks of waiting for an environmental analysis often needed in redevelopment projects into a few hours.

"We're able to get an answer quickly in high resolution that's easy to understand," said John H. Sohl, chief executive officer and co-founder of Columbia Technologies. "So you can move the market elements of a property transaction much faster."

The company's technology works by inserting a probe in the ground, sending data about the contaminants it detects in the soil to a computer. A three-dimensional, high-resolution image of the underground area covering about 50 feet is generated. Information on the underground contaminants is collected and used in the planning of the project.

"A developer is going to want to know how big and extensive the problem is and how much it's going to cost to bring it back to fruitful use," said Sohl, a former nuclear submarine captain.

"We have a broad appeal," said Ned Tillman, president and co-founder. "Environmental types like us for our less invasive procedures, but businesses like us because we can save them a lot of money. We're in a pretty good position."

The 6-year-old company has found a clean and fast way to measure subsurface pollution. While giving the environmentally concerned reason to cheer, Columbia is doing its share to keep commerce, particularly the real estate marketing, humming.

"Real estate transactions can close a lot faster now," Tillman said. "Before, a lot of deals would fall apart because of the time it would take to find out if there was contamination on a property. With our technology you can know that in a day."

The Catonsville-based company is now entering a growth phase. After spending its first three to four years engaged mostly in research and product development, the company has experienced "significant growth" over the past two years, according to Tillman. Business is expected to increase 15 to 20 percent annually for the next several years.

Columbia currently does about $2 million in annual revenue and is profitable, CEO and co-founder John Sohl said.
