The content of aluminum, boron, chromium, manganese, cobalt, nickel, copper, zinc, arsenic, cadmium, barium and lead was analyzed in raw water and drinking water that is used by the Belgrade Water Supply and Sewage Company. Total of 14 samples were examined from all water treatment plants that are part of the Belgrade Water Supply and Sewage. The measurements were conducted using the inductively coupled plasma-mass spectrometry (ICP-MS) technique. The aim of this research was to examine the effectiveness of the process of drinking water preparation in the existing plants. In all drinking water samples concentrations of the elements were bellow the maximum allowed levels according to the Serbian regulations. Correlation coefficients for the elements, which were analyzed in this paper, show that three groups of elements can be distinguished. Boron, manganese, arsenic and barium are related to each other and probably originate from the same source; copper, nickel and zinc have lower mutual correlation coefficients, indicating a potential common origin; finally, lead, aluminum and cadmium are not in correlation with any tested element.
