MIN3P was designed to investigate reactive transport in saturated and unsaturated porous media in partial equilibrium systems. The model is capable of simulating groundwater flow, advective-dispersive transport of dissolved species and advective-diffusive gas transport directly coupled with a variety of bio-geochemical and inorganic reactions. To date, processes considered are aqueous complexation, oxidation-reduction, gas dissolution-exsolution, ion exchange, surface complexation, mineral dissolution-precipitation, and microbially-mediated degradation reactions (for a timeline of these code additions and references, please refer to the page on Development History). For references and published examples by category, please see Previous Work & Publications. Continued research and code development is ongoing through several researchers and graduate students under supervision of Prof. Uli Mayer at the University of British Columbia, who are listed below.
