The  question marks I have on my printout after your name are valid:

I never heard of an "effluent pathway" to possess a "concentration". I never
read of a concentration given in percents. I do not know what a "specific
concentration" is. Could you please reformulate your question?

I hope that your question should not read "If an effluent stream contains
U-235 and U- 238 in a concentration ratio of 0.1 could there be the ratio in
a sediment sample greater than 0.1?" I certainly do not hope that this might
be the case, because then enrichment of U-235 would be a very easy
procedure, using biological processes and would help to produce and
proliferate nuclear bomb-grade material.....
