In order to highlight the quality of the lake waters from the Bahlui drainage basin, we chose to analyse four principal lakes (Pârcovaci, Tansa, Chiriţa, Podu Iloaiei) and six secundary lakes (Aroneanu I and II, Ciric I, II and III and Cucuteni). The global presentation of the lakes’ water chemistry and quality is a sum of two different ways of analysis: the first based on standards (promulgated in 2006), according to which the lakes are analyzed as static ecosystem (the quality of the water corresponds to five different categories) and the second considering the lakes a dynamic ecosystem and working with the average of different quality parameters, from different periods. After we made the analysis, we showed that from the four first-order lakes, two (Chiriţa and Pârcovaci) can be included in the first quality category, and all the second-order lakes can be included in the third and fourth quality categories. This can be explained trough the clogging of the reservoirs or through the pollution caused by human activities in the hydrographic basin.
