Using water quality indices (CCMEWQ) in the Danube River surface water characterization of the five sampling points (Drobeta Turnu Severin, Calafat, Calarasi, Chiscani Braila and Gropeni Braila) and the Jiu (Isalnita) river has been shown to correspond good quality class, which means it can be used as a source of drinking water for the Drobeta Turnu Severin, Calafat, Calarasi, Braila and Craiova towns. Using water quality indices (CCMEWQ) in groundwater characterization, it has been shown that this corresponds to the: - good quality class for sampling points in Slobozia, Urziceni, Cosereni, Reviga Crunti and Victoria, which means that characterizes water quality parameters rarely or with little value violate the criteria for using it as a drinking water source - acceptable quality class for sampling points in Garbovi, Insuratei and Rosiori which means that characterize water quality parameters sometimes violate the criteria with a high value for use as a source of drinking water, but can be used as drinking water sources after a drinking process that includes several stages, namely decanting, coagulation, filtration and disinfection.Danube RiverSurface waterWater quality indicesJiu RiverProject
