    Abstract: Nitrate is an acute contaminant, which means a single exposure can affect health of persons. Potential source of nitrate include septic system, animal waste, commercial fertilizer and decaying organic matter. This study was conducted to investigate NO <SUB>3</SUB> pollution in both natural mineral waters and bottled/packaging waters in Iran. The water samples were taken from 24 provinces of Iran. Nitrate concentration in the natural mineral waters and bottled/packaging waters varied from 0-15 with the average of 5.37 ppm and 0-25 with the average of 6.47 ppm, respectively. Results showed that all of the samples were in maximum safe NO <SUB>3</SUB> concentration that was considered to be 50 ppm according to the World Health Organization. The most of both natural mineral water and bottled/packaging water (62 and 69% respectively) were in group 5-10. Based of the results of this study, only 4% of water samples were classified as having high risk to human health or environment.
