Three surface vessels, the M/V Horizon, the DE-365, and the DE-534 all
remained in the fallout area for five days making measurements and collecting
semples.
In all, 80 water semples were taken for Project 2.63 and 80 were
taken for Project 2.64.
Preliminary results show that over 30,000 square miles were contaminated
