Investigating the role of gas bubble formation and entrapment in contaminated aquifers: Reactive transport modelling
Richard T. Amos, K. Ulrich Mayer
2006, Journal of Contaminant Hydrology (87) 123-154
In many natural and contaminated aquifers, geochemical processes result in the production or consumption of dissolved gases. In cases where methanogenesis or denitrification occurs, the production of gases may result in the formation and growth of gas bubbles below the water table. Near the water table, entrapment of atmospheric gases...
