Coupling the dual isotopes of water (δ 2H and δ 18O) and nitrate (δ 15N and δ 18O): a new framework for classifying current and legacy groundwater pollution
Nitrate contamination of groundwater is a concern globally, particularly in agricultural regions where decades of fertilizer nitrogen (N) use has led to a legacy of N accumulation in soils and groundwater. Linkages between current management practices and groundwater nitrate dynamics are often confo...
