FORMER AIR FORCE PLANT 36BACKGROUND INVESTIGATION

• Prepared for
• Air Force Center for Environmental Excellence and
  Aeronautical Systems Center

PURPOSE FOR MIP AND PDB TECHNOLOGY

• Characterize lateral/vertical extent of cl-VOCs
  in soil and ground water
• Evaluate vertical distribution of cl-VOCs in
  ground water
• Provide real-time data on lithology and
  contaminant distribution

HISTORY AND STATUS OFCORRECTIVE ACTION AT GEAE

• GEAE buys AFP 36 in 1989
• Corrective action begins in 1990
• Numerous investigations/interim measures
  performed
• Approximately 150 monitoring wells on/off site
• TCE and TCA in ground water remaining corrective
  measure
• Investigate source of TCE/TCA at AF Plant 36
