this delay can be made up during the current FY.
Accomplisha) participation in a joint LLL-UH
ments to date include:
field trip to Bikini, where chemical and bacteriological
water quality was tested for a variety of groundwater and
cistern sources, and additional hydrologic observations
were made as well as field tests of aipha-dosimetry films;
b) a portable drilling system was purchased, assembled,
field tested and shipped to Enewetak, where it awaits a
field trip now rescheduled for March; c) 3H and related
data obtained over the course of the project has been
assembled, interpreted, and is currently being written up
for publication; and d) hydrologic modelling efforts have
been intensified.

Expected Results in FY 1979:
During FY 79 we expect to
complete the drilling and basic hydrologic testing of the
additional
shallow wells
designed
to
provide
the
necessary
data for a refined hydrologic model of Enjebi island.
mathematical model
development
is
already
As
in progress,
we
expect that model refinement will yield publishable results
in FY
9.
On Enjebi and other islands we will obtain
chemical, hydrologic, and radiological data on the groundwater changes associated with vegetation removal and other
recharge surface alterations associated with cleanup.
Plans,
and if possible, preliminary experiments will be carried
out to prepare to monitor the effects of the Runit I. scrap
encapsulation on the surrounding reef, island and lagoon
area.
When the lagoon circulation study is completed we will
integrate our island and lagoon tidal data with those results
to provide a general but detailed description of the interactions between the island groundwater systems and tidal
patterns in the ocean and lagoon.
Continued monitoring of

will
provide
practical
estimates of the potential for long-term utilization of the
fresh groundwater resources on these islands.
Expected Results
in FY
1980:
FY 80 will be the year of con-
clusion for most of the "normal" modelling and data interpretation efforts.
However, field observation of stress
responses and changes in the hydrogeochemical system as a
result
of
cleanup,
rehabilitation and
resettlement will
continue.
The results of these observations will be used
to test the models already developed, and to provide practical
assessment of the effects of the various activities and their
implications for the Enewetak people.
