Study of the Specifications of Some Chemical Standards for The Water of The Unified Tikrit City Water Project

This study was conducted in the laboratories of the University of Tikrit / College of Education for Girls / Department of Life Sciences / and quality control laboratories for the study of the unified Tikrit city water station project , which is located on the course of the Tigris River within Salah al-Din Governorate, where the study included five stages, starting with river water, sedimentation basins and preservation tank, and ending with the last stage liquefaction water for the Shuhada neighborhood, For the purpose of studying the properties and chemicals of the project water and comparing the results with standard specifications, and the study period extended from August 2023 AD to January 2024 AD, the study included measuring (pH, dissolved oxygen, biorequirement for oxygen, total basic, chloride ion, phosphate and nitrate), pH values ranged towards basal Where their levels ranged between (7.3-8) mg / liter and it was noted that the values of dissolved oxygen ranged between (5.4-9.2) mg / liter, and depending on the values of the vital requirement for oxygen the water was somewhat clean, so its levels reached between (0.5 -3.2) mg / liter, and the total basic values ranged between (106-256 ) mg / l and the proportions of chloride ions were within the permissible limits ofFor drinking, the values ranged between (17.216-136) mg/L, while for the concentrations ranged (2.120439 3.748021-) μg/L, as for phosphate, values ranging between (0.6-2.7) μg/L, the results show that the phosphate values did not conform to the Iraqi standard specifications No. 417 for drinking water (2001) of 0.4 μg/L.
