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 2+] > 50 mg / L). The rate of sulfate ions average 638 mg / l, exceeding the maximum allowable concentration (MAC) recommended by WHO ([SO42ˉ] > 250 mg / L). In addition, 85 % had excess fluoride [Fˉ] > 0.85 mg / L, and 100 % are calcium, the rate of Ca2+ is greater than 150 mg / L.
