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.
