Abstract：For groundwater contamination management and contamination source identification, we collected 50groundwater samples in 2009 at Jilin City and 17parameters were tested for each sample. The Factor Analysis (FA) method was then employed to assess the degree of groundwater contamination in the shallow aquifer and identify the contamination source. Five factors (F1~F5) were extracted to represent transmission and enrichment, phosphorus emission, ammonia-nitrite-nitrates pollution, organic pollution and natural geologic environment, respectively. In addition, F1 and F5 represented environmental influence factors, F2~F4 represented human influence factors. As a result, the groundwater pollution was mainly induced by domestic and industrial wastewater discharge, industrial waste residue, fertilizers and pesticides used in agriculture. Moreover, according to the spatial distribution of five factors, we found that the groundwater pollution was more serious in the central and northern part of the city and becomes better in the south. Based on the resulting pollution distribution, three areas of the ban exploiting, no drinking water, drinking water were divided to support the exploration of groundwater resources in the shallow aquifers.
