Abstract

Contaminant concentrations in aquifers can change as chemical reactions occur during groundwater transport through the aquifer. For instance, denitrification, in which the contaminant nitrate (NO3) is converted to molecular nitrogen (N2), reduces NO3 contaminant loads. It is useful to understand the rates at which denitrification and other reactions occur in an aquifer to improve understanding and prediction of contaminant migration.
