Ephemeroptera, and Plecoptera and also Trichoptera (EPT) are the main biomarkers in the evaluation of the health condition of the aquatic ecosystems. The new river classification methodologies in quality classes have been tested and mostly harmonized at European level. This paper followed the distribution mode of EPT in the Sasar river basin and evidencing their biomarker quality. %K Normalized Global Biologic Index %K EPT %K monitoring biologic methods %U http://www.fileden.com/files/2008/10/15/2144000/2008/036-040%20-%20Mare%20Rosca%20Oana.pdf
