Present Limitations and Future Prospects of Stable Isotope Methods for Nitrate Source Identification in Surface- and Groundwater
Nitrate (NO3-) contamination of surface- and groundwater is an environmental problem in many regions of the world with intensive agriculture and high population densities. Knowledge of the sources of NO3- contamination in water is important for better managing water quality. Stable nitrogen (delta15N) and oxygen (delta18O) isotope data of NO3- have been frequently used to identify NO3- sources in water. This review gives a summary of typical delta15N- and delta18O-NO3- ranges of known NO3- sources, constraints and future outlooks to quantify NO3- sources and describes three analytical techniques for delta15N- and delta18O-NO3- determination.
