Soil profiles taken in 1971 reflected the construction earth-moving

activities, with plutonium and other radionuclides found in rather constant
or increasing concentrations down to soil depths of 20 cm -- the limit of
that sampling effort.
Although no burial grounds were indicated in those records researched,
it was highly probable that burial grounds of sorts were associated with
each SGZ area.

Evidence of construction was everywhere.

This background was taken into account when the information requirements
were formulated.

The statistical sampling program was then designed to

determine the following information:
l.

Stratify the surface (0-5 or 0-15 cm) into five arbitrary groups

+ 25% of strata mean.
2.

Define contamination to depth of 180 em (6 ft.) over large (not
small) areas.

3.

Determine only large volumes of contaminated soil.

SALLY (AOMON)-RUBY (EHERIRU)-SALLY'S CHILD were grouped together.
Presently RUBY is integral with SALLY.

SALLY'S CHILD developed from the

debris and sand from between SALLY and TILDA, and was treated as part of

SALLY.

Both SALLY end RUBY were the sites of multiple SGZ's. Buried contanination was expected, but not necessarily located prior to the survey effort.
An additional complication, that of Project PACE excavation, affected the
utility and the execution of a meaningful soils effort.

SALLY had huge areas

excavated by PACE, some adjacent to SGZ's and suspected burial sites.

Also,

the excavated material had been deposited on the remaining surface areas of
SALLY and between SALLY, and what remains of RUBY.

Because of this an attempt was made early in the survey to
