Healy:

DNA is worried about records at Enewetak.

There is no quality control at the lab out at Enewetak. (The

manager, chemist, etc. belong to Eberline, while the lab

staff are Air Force and Navy personnel.)

DOE will not referee the Eberline lab.
The method of data reporting is terrible.

Bair:

Let's come back to us.
Thompson will draft response to coconut trees.

Subsurface Contamination
Bair:

Background--

Backhoe diggings found high levels below the surface.
The questions relate to areas accidentally stumbled upon.
Healy:

How much higher than the guidance are the subsurface levels?

Barnes:

Boken - about 100 times higher (~3,800 pCi/g), but this is
in a small volume.

Enjebi - about 10 times higher (~100 pCi/g), although there

are places up to~270 pCi/gm at depths of 40-100 cm.

We're stymid by the limitations of the Op Plan.

-

Discussion of operational problems of identifying areas
and degrees of subsurface levels.
(These are better
defined on Boken than on Enjebi.)
Soil values are erratic which exacerbates the subsurface
problem, and makes putting confidence on values extremely

difficult,
Wachholz:
Barnes:

If the Op Plan could be changed, how would you change it?
Except for 1 area, we have prospected only in areas already
suspect, such as ground zero areas and suspected burial

areas (e.g., Enjebi has both).

If the Op plan could allow defining a boundary instead of
determining concentration it would be a big help. Guidance
is needed to determine:

1)

criteria of what is high enough to consider it
high (160 pCi/gm), and

2)

what distance defines boundary.
