Based on a hydrogeological survey, a total of 92 wells were settled, nitrite nitrogen (NO₃^--N) is the main contaminant of groundwater in new lakeshore district (NLD) of Hefei city. Multivariate statistical method factor analysis (performed using SPSS 13.0) was used to analyze the NO₃^--N characteristics and related factors. A three-factor model was suggested and explained 74.3% of the total related groundwater quality variation. Factor 1 includes Ca²⁺, Mg²⁺, Factor 2 includes Na and Factor 3 includes NH₄⁺ and NO₂^-. The result indicates that Ca²⁺, Mg²⁺, Na⁺, NH₄⁺ and NO₂^- have positive effect on the nitrate pollution in the study area, pH and HCO₃^- have negative effect on the nitrate pollution.
