Abstract
In order to verify the nitrite pollution risk assessment method. Pointing at nitrite pollution risk of groundwater caused by agricultural nonpoint-source pollution, alluvial-proluvial fan in Shenyang is as an example to analyze nitrite contamination risk of groundwater. Factor analysis in SPSS18.0 is used to analyze X-ray diffraction results,organic matter and nitrite content of vadose zone lithology samples, nitrogenous fertilizer is determined as the source of nitrite in the soil. On this basis, pointing at the lack of traditional DRASTIC model, combing with the actual characteristics of the study area, we propose DRSICLN model. Based on GIS software, nitrite pollution risk in the study area is graded in three levels, combing with the NO2-N contour map of groundwater. The results show that the DRSICLN model is fit to assess pollution risk of groundwater.
