Drinking water must be health providing, clean, devoided of pathogenic bacteria, viruses or parasites. Wells water should be checked periodically to determine if it complies with European standards, especially when these waters are used by the population. The aim of this paper is to assess the number of aerobic bacteria, nitrites and ammonium content for 7 location (Alba Iulia, Rosia de Secas, Cenade, Sancel, Spring, Ciugud, Ohaba) from Alba County, Romania. The results show that anthropogenic pollution affecting water quality from wells. The microbial growth varies between 42 CFU in source from Ohaba and 440 CFU in Ciugud. Starting from the nitrogen cycle, for the interpretation of the data a simple linear regression was performed. For all the casese, also a multiple regression was conducted to investigate the relationship between chemical parameters and the bacterial growth. A significant correlation between the microbiological growth and its nitrites and ammonium content was observed.
