Errors are two-sigma, propagated, counting errors.
Particulate--that portion retained by the 0.3 u filcer.
bsoludle--thae portion which passes through the 0.3 u filter and is sorbed by the Al,0, beds.
ANS--not significant.
The net sample count is less than the two-sigma, propagated counting error.
S8This sample was collected over a 6 hr period between the following positions:
11929'5" by
164°58'0" E to 11924'5" N by 164018'D" E,
