DSI employs the most advanced instruments and techniques available and teams with the leaders and pioneers in the field of expedited site characterization. Whether it is combining Laser Induced Fluorescence with Cone Penetration Testing (CPT), or using state-of-the-art GC Mass Spectrometers to identify contaminants brought to the surface with a Membrane Interface Probe (MIP), DSI has the scientific instruments and the prowess to perform.
The DSI history of accomplishments of “firsts” in the site characterization industry is long:
- In 1998, DSI personnel designed one of the first MIP platforms to service clients. At the time, it was a state of the art Membrane Interface Probe (DPT/MIP) platform.
- In 2001, DSI personnel created the first Environmental Data Acquisition Vehicle (EDAV) for several MIP service providers.
- In 2004, DSI personnel developed and applied one of the first commercially available Cone Penetration Technology & Membrane Interface Probe (CPT/MIP) platforms in the US.
- In 2006, DSI personnel developed the first CPT/MIP/Fluorescence platform designed to specifically identify petroleum Non-Aqueous Phase Liquid (NAPL) with 2 cm of resolution.
- Since 2006, DSI has designed, built and perfected the technology of a “single rod strand” to acquire all of the needed analytical and scientific information on the environmental soil and groundwater condition at the site. This concept is called “Single Borehole Utilization” and focuses on maximizing the cost effectiveness of a single mobilization of a field crew to comprehensively access assess a site with reduced mobilizations.
