[Sanitary evaluation of water taken from the water supply used by the inhabitants of Łódź].
The aim of the work was the microbiological evaluation of water taken from the popular water intakes used by the inhabitants in Łódź. The examination of water was performance directly after sampling, after 48 hours of the storage at temperature 0-4 degrees C and also after the storage at the room temperature. 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 degrees C temperatures and at the room temperature an increase of bacterial contamination was observed--especially bacteria growing at temperature 22 degrees 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 10(2) cfu/ml. During the storage of water the increase of fungi population was not observed.
