I am proposing a small feasibility study in SE New Mexico that will consider 15N and 18O in NO3. To date I have had difficulty locating labs able to do the analyses. The project will involve a pilot study of about 12 samples. The project is to be sponsored by both governmental and non-profit agencies. If successful, the program will be expanded to cover more area, although it will never become a work burden or a significant revenue source for a lab! I can be pretty loose on turn-around time, but would like to be able to show the sponsors a couple alternatives on labs. If your facility would be able to accomodate such a study after January 1998, I would appreciate hearing from you -- either directly or through the list.
