RaportInterpretation of resultsThrough the annual average values presented in the graphics will be interpreted the stateof waters in the Ibri River basin, by providing annual average values for each parameterof each river of this basin.The dissolved oxygen (O2 dissolved) – it varies from one station to the other. But it maybe concluded that in all water streams of this basin has O2 dissolved except in PristinaRiver at Bresje, where lower quantity is registered.If we compare the values of 2007 with those of 2008, it is not indicated a huge difference.The highest O2 value is measured in the Drenica River (at Krojmir) of 13.8 mg/L, whilethe minimum value in 2007 is registered in the Prishtina River (at Bresje). It has to beconsidered that these are annual average values. There have been cases during monthlymonitoring dynamics in this monitoring station (Bresje) no dissolved O2 is registered.The same situation is registered for the years 2008 and 2009.1614121086420ReqiceMillosheveBablakmg/lLipjanVragoliPlemetinMitroviceKushtovPodujevedaljeMitrovicedaljeKelmendBresjeVragoliKrojmireVragoliPetroveDavidovceLlapi Sitnica Ibri Prishtina Graqanka Drenica ShtimjaViti 2007 Viti 2008 Viti 2009Figure 15: Dissolved oxygen in the Ibri River basinBiochemical Oxygen Demand (BOD5) – Among all measuring stations, the highest values for2007 and 2008 are registered in the Prishtina River (at Bresje) where regularly are indicatedhigher values than in all other stations of the network for surface water quality monitoring inKosovo. While comparing data between the registered values for 2007, 2008 and 2009, onlyminor changes are indicated, that means the water quality in this basin continuously is at thesame condition. The maximum value of BOD5 is registered in Pristina River (at Bresje station)with an annual average of 19.8 mg/l for 2007 and 18.43 mg/l for 2008, while for 2009 this valuewas 15.1 mg/l. The lowest values are showed by measurements on river water springs.92120 © Agjencia e Kosoves per Mbrojtjen e Mjedisit

For 2009 the valuesrange from 7.34 to 8.23. Generally, these waters belong to a poor alkaline environment.© Agjencia e Kosoves per Mbrojtjen e Mjedisit93120
