Expedited site characterization:
TECHNOLOGIES USED
HYDROLOGICAL
Hydrological technologies are fielded to help us
understand the physical characteristics of groundwater movement and the properties of the ground which affect that and therefore predict "fate
and transport" of the target contaminants.
- Tritium/Helium3 Groundwater Dating
- Chlorofluorocarbon Groundwater Dating
GEOPHYSICAL/GEOTECHNICAL
Geophysical and geotechnical technologies are fielded to help us
understand the subsurface geology and therefore help predict "fate
and transport" of the target contaminants.

DATA INTEGRATION-Visualization
Data Fusion technology area consists of software systems designed to rapidly
integrate or fuse all site information into a conceptual site model that then
becomes the decision making tool for the site team to plan the subsequent
sampling activity.
- 2D and 3D Data Visualization: earthVision
DATA INTEGRATION-Data Management
- Microsoft Excel
