Depending on the concentrations at which they are present some of the constituents of water impart specific properties to the water On this basis we can distinguish waters of varying hardness salinity or CO 2 saturation () The temperature of the water is also a significant parameter on the basis of which cold and thermal waters are differentiated the latter can be further subdivided into
