Due to nitrogen fertilizers consumption and unsafe wastewater networks of cities, now nitrate pollution is one of the challenging issues of surface and groundwater pollution. In case of this contaminant present in drinking water causes ‘Blue Baby’ disease for infants, cancers, and harmful for pregnant women. So, it is very important to assess nitrate concentration for maintaining better health precaution. Nitrate concentration, dispersion and its distribution status were evaluated in Warangal District, India. The samples show that nitrate concentration in Warangal is very high in both urban and agriculture area which have maximum level of 49.5 & 83.3 mg/ liter as (NO3 – N); average value of 40.3 and 69 mg/l respectively. Even though in urban area the amount of concentration is somehow low, but it also is in harmful level. Nitrate dispersion could be observable from the high standard deviations which are 7.4 for urban area and 12.065 for agriculture area, it means nitrate dispersion in agriculture area is more than urban area’s groundwater and it is clearly observed from normal distribution curves. This high spread out on nitrate concentration shows many variations of nitrate sources from many different locations that various amount of nitrate pollutions is infiltrated into groundwater.
