ABSTRACT
Background and aim: Water is one of the most important limiting factors to receive sustainable development, in addition to, if it is at dangerous to its quality limit. The objective of this study was to determine water quality in central part Qanats of Birjand. 
Materials and Methods: For this reason, factors of ammonia, hardness, calcium, magnesium and, also nitrite, chlorine, dissolved oxygen, temperature and pH were measured in four regions. Physico-chemical parameters concentrations in the water samples were analyzed using Palintest. Also, a Pearson correlation (r) was used to identify any relationships between parameters. 
Results: The results of this study showed that mean concentrations of total hardness, ammonia and calcium were found to be range 490-504, 0.1-0.2 and 85-125 mg/L, respectively. Concentration of nitrite, chlorine and magnesium were determined at range 0.05-0.09, 0.09-0.30 and 39-42 mg/L, respectively. Also, concentration of temperature and pH were measured at range 20.1-21.2 °C and 7.5-8.2, respectively. The results showed that between the temperature and nitrite concentration in different regions observed there were significant correlation (p<0.05). 
Conclusion: according to our results, total of physic-chemical parameters of water samples in central part Qanats of Birjand was lower than the health standards and no problem to use for human.
