ABSTRACT
The quality of surface water in watercourses in the region of Lublin agglomeration was studied in 2012–2014. Biological and chemical indicators of the study for various sampling sites were detected and the resulting values of the indicators were processed statistically. Rivers characterized by small size and the flow and modification of the riverbed. The resulting low values of macrophyte river index and infusorial index pointed to a poor quality of surface waters. Chemical indicators of the quality of surface waters reached low values, only BOD and phosphates reached high values. The river is located outside the city and it is characterized by moderate potential ecological (III quality class), and the river within Lublin is insufficiently potential ecological (IV quality class). Statistical analysis showed high variability index values between the studied positions.
