Abstract: Nitrate pollution of groundwater has become a widespread concern. The most fundamental solution is to find the source of nitrate and cut it off. Different sources of nitrate have different N, O isotopic composition. The use of δ15N and δ18O on a tracer study in nitrate pollution of groundwater is currently an important direction. This paper describe many pretreatment methods、analysis technologies of N, O isotope、existing problems and future development directions.
