Dear Linda:

It's just to say that last week I receipt your publications that you send
me. Thank you a lot. I began to read your article and the chapter of the
book. I think it will be very interesting for my knowledge and my work
because it gives a little different point of view of what I read before, and
also it is a very detailed work.
The major part of the bibliography I read until now is from hydrogeologyst's
works, where they have worked with 15N-(NO3-(NO2)-NH4) and 18O-(NO3-(NO2)).
As you said to Carol, I think that there are lots of publications that will
also be interesting for your work as a complement of your point of view. If
you want I can tell/send you some of them, which I'm sure that Carol know
them as well. You can also ask her if you want.
Thanks again
cheers
Laura


Dear Carol:

For a less pessimistic perspective of the uses of N and O isotopes you told
me two reviews that I could look. But unfortunately I couldn't find them in
my University library. Even so, I have already read two differents reviews
from ARAVENA, R. (1993 and 1998), and some other scientifics writing abaout
N and O isotopes in groundwater.
But if you think that those two that you have told me, they are, very, very
interesting I would like to have them and I will be very pleased if you can
also send them to me in the adress below. It will be very gratefull.
Thank you a lot.
Best wishes
