摘要

Biogeochemical processes were modeled along a central flow path in a landfill leachate plume (Banisveld, the Netherlands) using the forward reactive transport model PHREEQC 2. The following processes needed to be included in the model to explain the observed development in groundwater composition: microbially mediated oxidation of DOC coupled to Fe(Ⅲ)-reduction, kinetic precipitation of calcite and siderite, cation-exchange and proton buffering.
