MDAG Case Study 15
As a result, columns may provide an estimate of on-site concentrations ("Rate2"), rather than primary reaction rates which are typically higher, with the difference ... provide estimates of on-site concentrations, rather than primary-mineral reaction rates, and they often retain reaction products. Wheel studies have shown, for example, that aqueous concentrations (as mg/L) ...

MDAG Case Study 29
Thus, processes like dilution and kinetics can play significant roles. Also, nitrogen species are redox reactive, so that nitrate, nitrite, and ammonia can convert among themselves, raising concentrations ... contained nitrogen, aqueous concentrations of the three nitrogen species often became detectable after November. Through November to February, maximum concentrations for ...
