  This study is performed to investigate the bacterial contamination of the water resources and the pipeline networks of the city. Faecal coliforms (such as Escherichia coli (E. coli) as the most important indicator of water contamination), non-faecal coliforms and Pseudomonas aeruginosa (which have recently been introduced as a new indicator of water contamination) as well as the number of phototrophic bacteria are examined. Samples collected from all wells, a big reservoir supplying big part of the city’s water (called Khordad 15 Dam), main pipeline networks, settling and resting reservoirs and finally treated water consumed by people under a sterile condition. The results showed 25% of samples from main water resources of Qom city were contaminated with confirm but no contamination detected in treated water. 16.7% of were samples were contaminated with Pseudomonas aeruginosa after subculturing to Acetamid broth, but 11.8% of treated water samples confirmed to be contaminated with this bacterium in the second subculture. Although the results of this study demonstrated the potential threats of bacterial contamination (such as coliforms) in water resources, Qom’s fresh water is safe and water treatment facilities there work quietly efficient and remove all coliform contaminations. The appearance of Pseudomonas aeruginosa contamination in drinking water is a sign of pipeline network cracks and erosions which require new efforts to repair and renew them.
