This paper was conducted to evaluate the quality of the drinking water supplied by the Tikrit University water station plant. The study was conducted in March 2019. Several physical and chemical characteristics were used for the assessment purpose. These characteristics included temperature, electrical conductivity, residual chlorine, turbidity, total precipitation, magnesium, calcium, total dissolved solids (TDS), total suspended solids (TSS) and total solids (TS). The obtained results were compared to Iraqi Standard for Drinking Water (no. 417, 2001), which showed an increase in the values of variables, especially turbidity (192 NTU) and residual chlorine. As for chlorine, it (33%) was higher than the allowed limits. The total hardness value within the allowed maximum limit ranged from 309-360 mg/L. TDS, TSS and TS were within the allowed limits. Magnesium values were within the limits. 90% of the calcium was within the normal range.
