Abstract
Agriculture can impact negatively water quality, often through the export of nutrients (particularly nitrogen (N) and phosphorus (P) from the root zone), resulting in eutrophication of surface water and pollution of groundwater. Increasing demand for use of water resources can led to concerns about deterioration in water quality. Water samples were taken in three different locations of Devolli River. Chemical water quality data are obtained from the analysis carried out in the Laboratory of Water and Soil, Fushe-Kruje, in order to assess the quality of Devolli river water. Electrical Conductivity (ECw) data show that most often ECw values falls into the ‘good’ category, while an increase in salt concentration along the river course may result due to various anthropogenic activities in the area. The end users of Devolli River need to pay more attention to the quality of their irrigation water. Hazards due to sodicity will also need attention. Nutrient enrichment was evident at many of the river sampling points. Further research also in lower parts of the river is needed.Keywords: Water quality, nutrients, salinity, sodicity, Devolli River
