Once we examined their physic chemical characteristics, we compared them to Algerian standards for mineral and spring waters, as well as international standards. (O.M.S). subsequently, we analyzed and classified these waters using both hydrochemical methods such as the Piper, Sholler Berkaloff and Gibbs diagrams. Based on their nitrate content, bottled water was, classified according to the nitrate pollution index method. This method plays an essential role in the detection of pollution, which allows us to choose our water properly.enOther
