| Abstract | ||
| The current study is conducted to evaluate the efficiency of the drinking water pu-rification 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 sedi-mentation 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 , calci-um 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 oxy-gen concentration, it was high in the spring season, reaching (9) mg / Liter and the con-centration 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 concen-tration 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, especially in the spring season, as the values of the total number of aerobic bacteria ranged between (17.6-3) × 103 cells / ml, while the values of the total number of coliform bacteria were between (4-4) cells / 100 ml. | ||
