to exploration to locate other possible subterranean pockets.

stated that the available data was not extensive enough to support a contention
that other pockets did not exist.

For purposes of certification there would

have to be edditional data taken.

The same mcthod of obtaining data for

certification applies to all islands.

This consists of in-Sites and surface

soil sample surveys, and investigation of suspected burial sites, supplemented

by selected soil profiling data.

Obviously, the greater the density of soil

sampling profile data, the lower the chance of being surprized later in the
cleanup.

After extensive discussion, the following was proposed and accepted.
northern half of the island will be gridded on a 50 meter grid.

The

The "cool"

area will be sampled first in order to characterize the areas to be used for
stockpilmg of soil and debris from other islands.

Approximately 16 to 50

sample sites will be required, depending on initia] findings.
be decided based on stockpile locations.

Areas are to

Sampling transects should be cut

through the mounds in this area to characterize the contents thereof.
Characterization of the extent of subsurface pockets can use an adaptation

of the one half distance technique, working along the 50 meter ‘erid lines.
Density of other sampling in the “hot"’ areas can be decided on basis of data

obtained from the “pocket” investigation.
Use of the standard 350 meter: grid will permit use of data obtained
during characterization for consideration for certification.
