Ammar Zobeidi, Leila Moussaoui, Physico-Chemical Quality of Drinking Water in the South of Algeria (Case of El-Oued Region) Study of Excess Minerals, Volume 16, International Letters of Chemistry, Physics and Astronomy (Volume 16)
    The Aim of this Study was to Determine the Physicochemical Composition of Water Intended for Human Consumption in Several Regions of El-Oued - Algeria. Excess Minerals in Drinking Water, Including Magnesium, Calcium, Sulfates, Chloride and Fluorides Play a Fundamental Role in the Prevention of Urinary Calculi, which are Formed Mainly from Calcium Oxalate. the Results Revealed that Wholes Water Samples are Analyzed Magnesium ([Mg <sup>2+</sup>] &gt; 50 Mg/L). the Rate of Sulfate Ions Average 638 Mg/l, Exceeding the Maximum Allowable Concentration (MAC) Recommended by WHO ([SO4<sub>2</sub><sup>ˉ</sup>] &gt; 250 Mg / L). in Addition, 85% had Excess Fluoride [Fˉ] &gt; 0.85 Mg/L, and 100% are Calcium, the Rate of Ca2+ is Greater than 150 Mg/L.
