The sulfuric water in Iraq is considered one of the polluted water resources due to their high sulfur contents which reach about (1000 ppm) in Iraqi sulfur springs which consider more than the permitted rate in the global scale limiting (200-400 ppm). So, this study was conducted to treat the water of the sulfur springs by using magnetic techniques, through the identification of the physical and chemical traits before and after treatment as well as determining the validity of these types of water for different uses. The Mosul city contains several sulfur water springs which located in (A) Mosul dam area, (B) area of Ein Kebriet in the center of Mosul, and (C) area of the Hammam-Alalil, where the sulfur water causes contamination of the surface water due to flowing towards the Tigris River. So, magnetic techniques were applied; where the sulfur water was passed for a period of (15 and 30 minutes), through a closed mgnetic circuit of a device which generates a magnetic field of (1000 Gauss). We found, that after the treatment by the magnetic techniques the physical characteristics changed when the yellow sulfur color disappeared and converted to the transparent color. Also, the sulfuric odor disappeared while the chemical properties such as the pH values found its change; in the site (A) from 6 to 7.1, in the site (B) from 6.5 to 7.4 and in the site (C) from 9 to 8.4. Moreover, electric conductivity (EC) decreased; in site (A) from 1721 ppm to 17 ppm, in the site (B) from 1414 ppm to 15 ppm and in the site (C) from 871 ppm to (9) while the total dissolved solids (TDS) values increased in the site (A) from 3.5×103 ppm to 3.8×103 ppm, in the site (B) from 2.8×103 ppm to 3.1×103 ppm and in the site (C) from 1.7×103 ppm to 1.8×103 ppm. Due to the efficiency of treatment by increasing the solubility of water contents, and decreased the sulfate values (SO4) in site (A) from 1392 ppm to 144, in site (B) from 945 ppm to 95 ppm and in site (C) from 247 to 26, due to their conversion to hydrogen sulfide gas and their volatilization in the atmosphere, which is caused by a fault odor in the laboratory. Thus, the flowing of the treated water to the river contributes in the enrichment of surface water, also possible for its investment in agricultural irrigation.
