Study Of The Specifications Of Some Chemical Standards For The Water Of The Baiji Unified Water Project

Abstract

This study aimed to demonstrate the effect of chemical properties on water in Baiji district, which includes determining the quality of this water. The study began in September 2024 and continued until February 2025. The study included some chemical properties such as (salinity, pH, dissolved oxygen, total alkalinity, total hardness, calcium hardness, magnesium hardness, and biological oxygen demand, in addition to some ions such as chloride ion, sulfate ion, nitrate, nitrite, and phosphate). The results were compared based on international and Iraqi standards. The results of this study showed that the highest value of salinity was 285 g/L, and the lowest value was (230) g/L. As for the pH, the lowest value was 6.4 and the highest value was 8, and its rates ranged between (7.23 -7.44), and its values ​​ranged between weak acidity and weak basicity, which is within the Iraqi water specifications. As for the dissolved oxygen, its rates ranged between (7.478 - 8.685) mg/L, while the biological oxygen requirement had its highest value of 168 mg/L and its lowest value was zero, while the total alkalinity ranged between (90 - 188) mg/L, and the total hardness ranged between (275.7-302.3) mg/L, and the calcium rates ranged between (61.17 - 64) mg/L, and the magnesium had its lowest value of 14 mg/L and its highest value of 77 mg/L, and the sulfate rates ranged between (70.7 - 72.5) mg/L, and the chloride ranged between (17 -36) mg/L, while the nitrate had a lower value of 2.598 micrograms/L and the highest value was 8.116 micrograms/L, and the nitrite had a lower value of 0.035 micrograms/L and the highest value was 0.759 micrograms/L, while the effective phosphates had rates ranging from (1.537 - 2.010) micrograms/L.
