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.
