376 . RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL FIGURE 7-37. REMOVING A SOIL SAMPLE. the soil sample. The bomb was then lifted from the water and the soit sample was placed in a I-gallon soil sample can. All samples weretaken at nodes of the S-by-5-meter grid system used throughoutthe project. The soil sample was dried, and preliminary readings of radioactivity were taken f with the IMP. The soil samples were then sent to Enewetak forfinal chemical analysis. AOMON CRYPT SITE RESTORATION Site restoration began on 7 May 1979 and was accomplished by Company B, USAE.The backfill material was clean beach sand from Bijire and from the lagoon shore ofthe land bridge between Bijire and Aomon (Figure738). Prior to backfill, DOE-ERSP ascertained that the beach sand met the desired criteria. As soon as enough backfill had been placed to assure proper supportfor the 45-ton crane, sheet pile extraction began. After the backfill and sheet pile extraction was complete, the entire Aomon Crypt area was broughtto grade and contouredto allow proper drainage toward the lagoon. Approximately 12,000 cubic yards of beach sand wereused to restore the site. The operation was completed on 30 May 1979. (ners
