In this study, water samples collected from public fountains in Erzurum city centrum were analyzed and their drinking quality was evaluated. A total of 45 water samples were subjected to microbiological, chemical and physical analyses. Microbiological analysis results showed that total and fecal coliform bacteria were found in 10 samples (22.7 %) and Clostridium perfringens in only one sample. In addition, Escherichia coli were isolated from these 10 samples. RAPD-PCR technique was used for confirming phylogenetic diversity among E. coli species isolated from various fountains. Six of 45 typical E. coli isolates were determined to be different strains. Average colour, water temperature, turbidity, electrical conductivity, pH, dissolved oxygen, chloride, nitrite, nitrate, sulphate, phosphate, sodium, ammonium, potassium, magnesium, calcium, iron and manganese values of the samples were determined as 1.04 mg Pt L-1, 21.43 degrees C, 0.14 NTU, 456.80 mu S cm(-1), 7.26, 5.36, 3029, 0.12, 2.09, 50.48, 22.71, 35.91, 0.32, 14.99, 31.20, 105.00, 0.16 and 2.64 mg L-1, respectively.
