city. Ninety eight percent of water samples of the city have nitrate values
above acceptable limit of 50 mg/L. It was observed that nitrate increased with
hardness, chloride, sulphate and total hardness while alkalinity, fluoride and
water table do not exhibit any significant effect on nitrate content.
Statistical analysis of the data is presented.
