The technical processes for nitrate sources identification are composed of siteinvestigation, sample collection and analysis, isotope analysis, source identification using isotope characteristics, andsource apportionment for multiple potential sources with the Bayesian isotope mixing model. Characteristics of variousnitrate potential sources are reviewed, and their typical ranges of δ15N and δ18O are comparatively analyzed andsummarized. This study also summarizes the current knowledge on the dual-isotope approach and how to correlate thefield-relevant information such as land use and hydrochemical data to the nitrate source identification.
