Ok, Please review the attached file. Problem: Product water is injected into an aquifer and begins to mix, simulated by progressive amounts of product water added to 1 liter of groundwater. What are the effects on manganese concentrations assuming birnessite solubility and redox are the controlling factors? Questions: 1. If I assume N2 and NO2 are stable, as in this file, manganese concentrations are held to 1 nM or less. However, assuming only nitrate and ammonia are stable results in >5 orders of magnitude increase in manganese concentration. Why does this occur and which state is more realistic? 2. Is the problem posed correctly in this file? Thanks for your time. -----Original Message----- From: David L Parkhurst [mailto:dlpark@xxxxxxxx] Sent: January 29, 2003 3:57 PM To: Schroth, Brian/SAC Subject: RE: Nitrogen redox Sorry, I can't go through all of these files and permutations.
