Most significantly, however, implementation of Option IV a-e would remove a minimum of 15 cm of soil from essentially the entire island of JANET. Since the top soil on that island is charitably described as meager, such action would leave JANET a sand island. Heroic actions would be required to either reconstitute the remaining soil through use of fertilizers and other additives, or import topsoil sufficient to support subsistence and commercial agriculture. With any of these actions a period of time would be required to determine the effectiveness of the action. An additional period would be required after a decision to plant subsistence and commercial crops in quantity before the island could support its inhabitants. Option V a.

If pandanus and breadfruit are to be grown on northern islands other than JANET, the criteria of Option IV c should apply, t.e., plant in soil having a 90... content of 4.6 pCi/gm or less, or bring clean soil to the island with a depth sufficient to contain the roots of these trees. If these actions achieved a level of exposure reduction as iarge as the calculational result, this would permit use of the entire Atoll according to the Master Plan. This option is clearly much more expensive than other ‘options since it requires removal of additional soil and requires recon- stitution of soil in the cleared areas. Consideration of these actions as a viable option is clouded by uncertainties regarding the exposure reduction that can be achieved through partial soil removal and by selective soil replacement. ~24-
