Blog & Recent Projects

 Since 2008, our team at COLUMBIA Technologies has supported site managers in evaluating petroleum contamination at 125 and growing projects using direct sensing or imaging tools. These projects include a wide-range of application from gasoline and diesel fuel retail stations to Superfund sites, as well as petroleum terminals, petroleum storage facilities, pipeline terminals, railyards, oil refineries, complex underground storage tank (UST) sites, military installations, and truck refueling facilities. These sites have spanned across 28 states in the United States including Hawaii, and multiple provinces in Canada. One primary technology deployed at these sites is the Laser Induced Fluorescence, specifically LIF-UVOST^® to determine the LNAPL distribution at these facilities. These experiences have provided us with a number of lessons learned about accurately, rapidly, and cost-effectively characterizing these sites using this technology. 

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.

     COLUMBIA Technologies is currently supporting our first high-resolution direct sensing project in Mexico City.  COLUMBIA’s direct sensing team landed in Mexico City in August to make a difference in the environmental industry on a global level and prove that real-time information can drive a project to satisfy regulatory requirements for investigation of contaminated sites.

Following the proven concept of stakeholder and regulatory involvement, systematic work planning, and dynamic work execution, these site investigations focused on providing a better understanding of how the results would impact the overall remediation scope and property disposition.

 Would a comprehensive site assessment and better data with multiple technology integration make a difference in your overall scope? Before you answer that question, think about whether or not having better, more accurate, and real-time information would motivate you to change your investigation technique on your next project. Are you actually interested in having data that accurately depicts the plume, delineates your source area, and multiple lines of evidence on your subsurface contamination? Or, would you rather “drill blind” and continue to sample areas where you think there may be contamination and install monitoring wells at the wrong depth and location incurring additional costs and time?

If having better data would actually change the way you would execute your project, design a remediation plan, or install monitoring wells, please read on. If you disagree, you may also continue to read, but the thoughts below may conflict with your perspective. Just saying, we warned you.

Data which is collected with advanced direct sensing tools (such as the Membrane Interface Probe (MIP), Laser Induced Fluorescence (LIF), or Hydraulic Profiling Tool (HPT)) provide a greater level of detail for characterizing the local site geology, a more in depth understanding of the hydrology, and deeper insight into the contaminant chemistry of your site. Wouldn’t all of this allow you to make more informed decisions?

 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.’”

Most recently, the March 2011 issue of Technology and Trends highlighted a project where COLUMBIA Technologies worked closely with the property owner, the Virginia Department of Environmental Quality (VA DEQ), and the City to address the site's environmental and economic issues.

Efforts to better delineate contamination and accelerate remediation of the former Fannon Petroleum Services site in Alexandria, VA, were initiated in the early 2000s as part of a plan to redevelop the site for residential use.

For this project, the VA DEQ initiated the Triad approach including the development of a conceptual site model and consensus on specific investigative methods and tools, with a focus on using:

1. Membrane Interface Probe (MIP) to characterize distribution of volatile organic compounds (VOCs) in discrete hydrologic units and soil stratigraphy at offsite locations;
2. Direct-sensing geophysical tools rather than groundwater and soil sampling for initial screening; and
3. A dynamic work strategy to allow real-time decision making that could identify specific locations for direct-sensing locations as work proceeded.

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.

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.

Historical data indicated potential contamination in the expansion area requesting for rapid resolution to address regulatory concerns. The client engaged in a site assessment with COLUMBIA to map the area of concern and compare this with the historical data using COLUMBIA’s award winning SmartData Solutions®. With a dynamic work scope and real-time data measurement the team bound the area of concern and closed data gaps to reduce the problem at hand for the client as well as the regulatory agencies.
