1 1 FORMER AIR FORCE PLANT 36 BACKGROUND INVESTIGATION Prepared for: Air Force Center for Environmental Excellence and Aeronautical Systems Center

2 2 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

3 3 HISTORY AND STATUS OF CORRECTIVE 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
