the analyzed samples for the content of phosphorus, river Drenica is in category of good water quality. The content of nitrates, ammonium and dissolved oxygen. The concentrations of these macro pollutants are shown in Tables 10-13. From the analyzing of collected data we can conclude that water quality of river Drenica belongs to good category. According to some analyses made in 1981, 19997, 2006 and on march 2007, only some samples had the content of dissolved oxygen under the limited value (lower than 7,0 mg/l), and the number of samples which exceed the allowed levels of ammonium are increased during 2006. However in 2007 there is an improvement in this regard. The content of micro pollutants The monitoring of the elements and substances which are classified as micro pollutants (heavy metals, sustainable organic pollutants and hydrocarbons) is not developed systematically in all sample places of river Drenica. However, there are monitored the concentration of heavy metals in particular areas and sustainable organic pollutants (pesticides) are not found. Regardless of low quantity, the pollution potential is higher in cases when we have to deal with hazardous substances. On account of decreasing of chemical industrial production we have the low level of hazard substances discharged in river. On the other side, urban household waste water is discharged in river without any prior treatment. Considering all these facts, the water quality of river Drenica has not shown big changes. From the collected data in monitoring stations and collected samples far from pollutant sources, we can conclude that the water quality of Drenica’s river fulfills the criteria of second category. It means that the water quality of river Drenica in generally is good.
