As
described
above,
profile
sampling
was
conducted
on
Irene
at
various
times
between
mid-November and early March. Several reasons account for the long period required to complete
this phase of sampling, chief among them being that sampling was conducted concurrently on other
islands as well. Table 6-6 presents a chronology of soil sampling missions during the
November-March period.
Surface samples were collected as a high priority task in order to
complete the characterization of the northern islands, but samples were not collected from an island
until a grid had been laid out and access lanes cleared. Plans were prepared and available for soil
profile sampling on ground zero islands and were implemented whenever they could be fit in between
surface sampling requirements.
Figures 6-17, 6-18, 6-19 and 6-20 show the locations sampled in the
early subsurface investigations conducted on test islands.

*Conduct of soil sampling on an island was generally planned for consecutive days; however,
mechanical problems with boats or backhoes, bad tide conditions and other unforeseen problems
interrupted planned missions on the following datess November 19; December 12; January 24;
February 6, 10, 14, and 20; March 2,7,13, and 27.
