Accomplishments

The VOCs in Non-Arid Soils ID served as the model for the ID approach to remedial technology
/system development. Major pro-
grammatic accomplishments for the ID are as follows:

• established national criteria for implementation of the ID concept for development of innovative environmental remediation solutions

(Photo B.1)
• transferred numerous tech-
  nologies and systems to EM’s Office of Environ-
  mental Restoration (EM-40), other government agencies, and industry (Photo B.2). Outlined approach for ID closeout.

Some of the major technical accomplishments for the ID include the successful demon-
stration of the following:

• in situ air stripping coupled with horizontal wells to re-
  mediate sites through air injection and vacuum extraction
• crosshole geophysical tomo-
  graphy (both seismic and
