The microbiological examinations of water in the aspect of detection of majority of microbes were conducted using membrane filtration method. Among 13 evaluated samples 11 were qualified to direct consumption. After 48 hour storage at 0-4°С temperatures and at the room temperature an increase of bacterial contamination was observed - especially bacteria growing at temperature 22°C and the higher. The presence of fungi was detected in the evaluated water. In 3 samples the mould count was exceeded 1,5 x 102 cfu/ml. During the storage of water the increase of fungi population was not observed
