Abstract: Efforts by members of the UND denitrification research team show organic carbon and sulfide are active electron donors for denitrification in aquifers in North Dakota and Minnesota. We also believe ferrous iron is an active electron donor; however, the geochemical evidence for ferrous iron is more difficult to interpret. To do so requires advanced computational techniques, such as incorporated in the computer code PHREEQC (Parkhurst and Appelo, 1999) produced by the U.S. Geological Survey.Therefore, our objective is to use PHREEQC in order to gain a more comprehensive understanding of the hydrogeochemical environment that governs denitrification by ferrous iron and associated aquifer reactions.
