The Impact of Al-Kharrazi Valley Discharges on the Water Quality of the Tigris River within Mosul City
The water quality of the Al-Kharrazi stream was studied as a potential source of pollution to the Tigris River in various locations along its course. The study aimed to assess the degree of pollution and determine the stream's suitability for irrigation purposes. Parameters analyzed included pH (acidity), electrical conductivity (EC), calcium, magnesium (Mg), sodium (Na), potassium (K), sulfate (SO₄), chloride (Cl), and bicarbonate (HCO₃), as well as the sodium adsorption ratio (SAR), soluble sodium percentage (SSP), residual sodium carbonate (RSC), permeability index (PI), and Kelley’s ratio (KR). The results indicated that, based on chloride concentrations, the water is not suitable for all types of crops. However, according to the sodium adsorption ratio (SAR), the water is suitable for irrigating most crops, except those highly sensitive to sodium. Overall, the study found that the stream water falls under the C3S1 category in the USSL classification, indicating high salinity with a low sodium hazard.
