The aim of the study was to determine the evolution of sulphates and lead concentrations in groundwater on the western area of Oradea (Romania). The groundwater is stored in Crisul Repede alluvial cone which is developed on both banks and the body of groundwater ROCR 01 is the source of drinking water supply of Oradea. In the 1960s was developed an industrial platform and after 1989, there were essential changes in the industrial economic structure. The water quality has been analyzed for a period of 40 years, starting with 1977. In order to monitor the evolution of the two studied parameters were used the data obtained by the Control Station of Industrial Pollution (CSIP) in the industrial zone, provided by the "Crişuri” Water Administration Basin. Based on this pre-existing database was studied the variation of the sulphates and lead concentrations and was observed that the surfaces with groundwater polluted with SO4 are reduced in the 40 years of observations by 48.78% and in the case of Pb the reduction is 51.83%.
