An Environmental Study for Assessing the Efficiency of the Drinking Water Purification Plant Supplying Some Areas North of Tikrit

The current study is conducted to evaluate the efficiency of the drinking water purification plant supplying for some areas north of Tikrit. The study samples were taken monthly, including a sample from the river outlet of raw water, a sample from the sedimentation basin, and the third sample from the drinking water line, starting from August of 2020 until March 2021. The study included, firstly, measuring some environmental factors, including (turbidity, pH, dissolved oxygen, Biochemical oxygen demand , calcium hardness, magnesium hardness , chloride ion) and secondly, microbial factors (total aerobic plate count, total coliform). The study has recorded high values of turbidity in the winter season, reaching (162.4) nephelometric turbidity unit, while the pH values were tending to be basicity, as their levels ranged between (8.3-7.1). As for the dissolved oxygen concentration, it was high in the spring season, reaching (9) mg / Liter and the concentration of the biochemical oxygen demand was high in the summer season due to the high temperatures, as its concentration reached (4. 3) mg / liter. The chloride ion concentration was conformity with compliance with international standards, it ranged between (55.6-32.7) mg / liter. The microbial study, it was found that the water is very polluted, the values of total of aerobic bacteria ranged × cells / while the values of the total of coliform bacteria cells
