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.
