Characterization and Monitoring (cont.)

1.2 The colloidal borescope provides high resolution magnified video information from water in monitoring wells.

1.4 Crosswell tomography by Lawrence Livermore National Lab., Sandia National Lab., and the U.S. Geological Survey provided unique and useful information at a reasonable cost.

Directional Drilling

2.1a A variety of positioning systems were tested during the Integrated Demonstration to track the progress of the borehole while horizontal drilling.

 

 2.1b One of the most promising drilling approaches tested in the Integrated Demonstration was modified utility installation systems.

In Situ Air Stripping

3.1 Rapid and inexpensive methods to analyse solvents in soil core were developed early in the in situ air stripping test planning.

3.2a Simple control devices, like the BaroBall, allow engineering control of natural processes.

3.2b Combining of processes, such as barometric pumping, and solar energy, promises to enhance the effectiveness of natural, or "green" remediation systems..
