The current study was conducted on drinking water to identify some of the physical and chemical properties of the drinking water station in the city of Tikrit - Al-Qadisiyah district, with four distributed sites since November 2018 to January 2019 for a period of three months by measuring the temperature of air, water, pH, D.O., BOD, E.C., salinity, hardness, chloride salts, nitrites and phosphates.The results of the current study showed that the temperature of air and water ranged respectively between (15.5 - 17.3) and (15 - 18.2) C°, while the value of E.C. ranged (52.60 - 61.05) μS/cm. As for the pH, the values ranged between (7.31 - 7.39) whereas the D.O. values ranged (2.06 - 2.5) mg/L, while the values of the B.O.D. ranged from (0.98 - 0.50) mg/L and it was noticed that this water had a low level of hardness, as the T.H. values ranged between (9.5 - 12.6) mg/L and Ca hardness ranged between (6.66 - 9.66) mg/L, while the Mg hardness recorded values ranging between (13 - 30) mg/L, while the salinity values ranged (1.51 - 1.55) g/L, while the Cl values ranged from (0.041 - 0.13). This study recorded low concentrations of phosphate values, as the values ranged between (0.04 - 0.27) μg/L of atom phosphate, while the values of nitrite ranged between (0.01 - 0.7) μg/L of nitrogen atom - nitrite.
