In this research microbiological status of water from three wells in a particular food factory was investigated. In raw water samples total number of aerobic mesophilic bacteria was determined with two methods - standardized and Petrifilm method which is in Serbia still an alternative method. Number of population of aerobic psychotrophic bacteria was also tested. ATP level was also analyzed. For classical microbiological method and quick method of evaluation of microbiological status correlation was reseached. Results show that coefficient of correlation was higher than 0.99 for the two applied methods. In most water samples the higher number of bacteria formed colonies when Petrifilm method was used. Connection between number of bacteria and level of total and free ATP is not statistically significant, while connection with variation of these values can be described as high direct linear correlation.
