The pollution of the aquatic ecosystem is an issue with great concern all over the world and due to this fact a national and international call of urgency has been made for a better management and better policies of water resources. In assessing the water quality, classical methods are no longer sufficient to express the complexity of the effects that pollutants have over the environment. Therefore, advanced researches have been made to acquire better methods and instruments for a cleaner environment. Utilizing microorganism and their metabolic activity for evaluating the water condition is not totally new but the research over these methods is improved by every study that is made bringing fresh perspectives in this area. In order to evaluate the quality of water and sediment, samples have been taken from three main areas of Castailor Creek (upstream of the city, industrial area and downstream of Bistrita city). Some groups of microorganisms, used as pollution indicators, have been assessed, and also the effect of pollutants on creek micro biota. The physical-chemical parameters of water from different sampling points were also determined. The quantitative enzyme activity has been assessed: actual and potential dehydrogenase activity, catalase and phosphatase activities. Based on the results, the bacterial and enzymatic indicators of water and sediment quality from Castailor Creek were also calculated. The main purpose of this research is to assess microbiological and enzymological indicators of pollution in the water and sediment of Castailor Creek, Bistrita.
