This study evaluates the physicochemical and microbiological characteristics of the saline waters of three representative lakes from Ocna Sibiului in order to promote their therapeutic purpose. The water monitoring campaign of the three investigated lakes, Brancoveanu, Gura Minei and Ocnita, was done from May till October 2011 after the rehabilitation of the infrastructure and the arrangement of the lakes from Ocna Sibiului resort requested by the Local Council of Ocna Sibiului from the Central Agency of Regional Development. Sampling was done twice a month (at every two weeks) at an approximate depth of 40 cm. Measurements were performed to emphasize the level of mineralization, organic load and the concentration of mineral substances. From the microbiological point of view the total number of mezofili germs which develop at 22ºC respectively 37ºC was pursued. The results led to a physico-chemical and microbiological specific profile for these lakes which are recommended to be used for bathing, therapy and leisure.
