High levels of nitrate in water destined for human consumption or recreational activity raise serious health concerns for humans and ecosystems. Resulting algae blooms can have disastrous ecological and economic consequences. The ability to identify the sources of high levels of nitrate in surface or drinking water is therefore a crucial first step in avoiding or remediating contamination issues.
One valuable tracing method available to water managers concerned about the risks associated with high levels of nitrate is isotopic analysis. Measuring the levels of oxygen (δ18O) and nitrogen (δ15N) stable isotopes present in nitrate (NO3) extracted from water establishes an isotopic fingerprint that can be used by water managers to identify the source of the nitrate.
