Resum
An integrated model of EIB is presented considering biogeochemistry and isotopes. Adding isotopes allows for the improved quantification of EIB processes. The organic carbon source can induce calcite precipitation or dissolution. Enrichment factors indicate the inverse fractionation of carbon sources. It is the first step in developing an integrated EIB model at the field scale. Enhanced in-situ biodenitrification (EIB) is a potential technology for remediating nitrate-polluted groundwater. EIB ...
