Lessons Learned
1.
Lessons Learned about the Operation of the Equipment:
Important to place SVE screened interval where the contaminant is likely located.
Strategic placement of valves in the piping system help account for the heterogeneous
nature of the site.
2.
Why was the Technology Successful?
Used passive injection wells (screened in vadose zone and open to atmosphere. They
increased vadose velocities and reduced stagnation zones.)
3.
Why was the Technology Unsuccessful?
