Abdalaziz Y. T. Al-Saffawi* and Mohammad H. Awad

ABSTRACT

The study was carried on Abu Wajnah village of Tal Afar district, which depends mainly on groundwater as a source of drinking water to know the health safety of this water on the health of consumers, especially the risks resulting from the presence of nitrate ions in the water , considering that the local people are engaged in agriculture and ranching, fourteen wells were identified for collecting water samples and the concentration of nitrate ions was determined with a Human Health Hazards (HHR) of nitrates calculated according to international standard methods. Fortunately, the results of the study registered that there is no risk to nitrates in drinking water for the health of consumers because the values of hazard quotient of nitrate (HInitrate or HQ for different age groups) ranged between (0.0228 to 0.1125) and thus it is within the limits allowed globally (less than 1), they attributed this decrease in values to the decrease in the values of chronic daily intake (CDI) of studied water, which fluctuated between (0.0142 to 0.1800). They attributed this decrease in values to the low concentration of nitrate ions, which was reflected in the values of chronic daily intake (CDI) of studied water which fluctuated between (0.362 to 3.20) ppm.
