Soil Cleanup Oper

FIGURE 7-38. AOMON CRYPT SITE RESTORATION.

Extracted sheet pile was monitored by the FRST, and those sections
requiring decontamination were cleaned on site by the USAE. A large
portion of the sheet pile (85 percent) was declared reusable and was

subsequently moved to Enewetak Campfor future shipment to Johnston

Atoll. Unusable sheet pile was treated as debris and dumpedatsite Bravo.
Upon completion of the excavation and restoration operation, DOEERSP again performed anin situ survey with the IMP. Additionally, they
used a simplified drill mechanism to obtain a 5-foot depth sample from 26
locations over the backfilled area. These depth samples were

homogenized, analyzed, and found to meet the required criteria. As on all

other soil removal projects, the work site, beach soil and debris stockpile
areas, as well as all routes taken bythe trucksin delivering the soil to the

water craft were surveyed by the IMP.
