A simple pool dissolution model was used to predict observed dissolved TCE concentrations.
Degassing was incorporated into multicomponent reactive transport simulations for the barrier and the simulations were successful in reproducing observed dissolved gas trends.
Considering only one fitting parameter, the model can reproduce well the observed dissolved oxygen evolution at different locations in the column.
It is our hypothesis that observed dissolved concentration in a monitoring well downstream of the source zone will provide inadequate and often misleading information on the entrapment architecture needed to design effective remediation schemes.
Studies of both freshwater and marine porewater constituents have observed dissolved Fe(II) in the presence of Mn oxides [13] and implicated Mn oxides as the relevant oxidants of Fe(II) in such systems [14].
The possibility of alternative pathways to N2, which may not be limited by organic matter content, oxygen, or observed dissolved inorganic N levels, have not been examined in these widespread environments.
