EVALUATING THE WATER QUALITY OF SOME WELLS IN AL-RIFAI CITY

Due to the scarcity of water resources at present time in Thi-Qar governorate, many people and farmers resort using groundwater well for all purposes meet their daily needs. Therefore, it is important evaluate quality determine its suitability different uses. researchers this study dealt with evaluating some physical chemical properties wells located Al-Rifai city governorate / southern Iraq during year 2020 purpose assessing water. Water samples were collected from 9 depths, ranging between 1-7 meters. The electrical conductivity, pH, turbidity total dissolved salts measured. concentrations major ions these wells, represented by chloride, carbonate, bicarbonate, calcium oxygen, also Analytical methods followed determining chloride ions, carbonate calcium, measuring (TDS), conductivity (EC), oxygen (DO) methods. It was found that concentration ranged (31.6 - 3.8 meq L) (43.26 71.8 L), while bicarbonate values ​​ranged (630 160 L). pH (7.38 7.5) EC (4.35 1.33 mmho cm), ​​of TDS (2175 666 ppm) DO (8.85 7.30 ppm). (FTU 105 0.05 FTU). through high, others within permissible limits, indicates contamination area. behavior a basic behavior. All form contour maps illustrate general distribution ​​in
