Utilizing Key Indicators in Evaluating the Water Quality of Water Channels in Al-Harthah District

Abstract

This study aims to assess and analyze the water quality of water channels in Al-Harthah district, southern Iraq, using eight key physical and chemical indicators. These indicators include ambient air temperature, water temperature, electrical conductivity, water transparency, pH, dissolved oxygen, total dissolved solids, and oxidation-reduction potential. Measurements were conducted at 124 sampling stations during both winter and summer of the year 2022. Aquameter and Seechi disk were used for measurements.

The study found an increase in electrical conductivity, total dissolved solids, and oxidation-reduction potential values, along with a decrease in dissolved oxygen quantity and water transparency. These values tend to increase in summer compared to winter, indicating that the water quality in the study area tends towards salinity, turbidity, and oxidizing environment. The study also indicated some statistical correlations among the studied variables.
