The aim of the study was to assess the concentration of salinity indicators in the Bystrzyca River in the city of Lublin, located in south-eastern Poland. The studies on the quality of water from the river were carried out from November 2018 to June 2019, i.e. in winter and spring. The water samples for analysis were taken from 9 measurement points located on the river under bridges and at high traffic roads. In total, 8 series of analyses were carried out, during which 72 water samples from the Bystrzyca River were examined. The samples were analyzed in terms of: water temperature, pH value, conductivity as well as concentration of chlorides and sulfates. An increase in both the specific conductivity and chloride and sulfate concentrations was found in the water from the Bystrzyca River during the period of low air temperatures (≤0°C), i.e. in December 2018 and January 2019. This may be a result of winter road maintenance procedures, i.e. by using salts for their defrosting. At the same time, an increase in the conductivity value and the concentration of chlorides and sulfates was observed with the course of the river, which indicates that the pollution generated in the city of Lublin has a negative impact on the water quality in the studied river. The salinity of the Bystrzyca River was greatly affected by the operation of the municipal wastewater treatment plant in Hajdów, especially by the use of coagulants: polyglycol chloride (PAX 18) and iron sulfate (PIX 113).

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.

River valleys are one of the most significant features of the urban landscape, for they contain both natural landscape elements as well as those of the architectural or built environment. River valleys aesthetically improve the scenery of the urban landscape, while their benefit towards society can be assessed in terms of both their intrinsic ecological value as well as their instrumental touristic and recreational worth. Early development of the town of Lublin centered on the River Bystrzyca, where it featured prominently as the central and integral landscape element. This has ceased to be the case, however, and as a result the town of Lublin has lost its direct historical connection to the river. It is now as if the town has grown and developed with its 'back' to the river, losing the connectedness that the two once shared. Local planners seem indifferent to the significance and natural value of Lublin's river valley, since they have not come up with a plan to develop it according to historical precedent. There are still some significant views of the river in Lublin: from local bridges, from urban districts on the high river banks and a partial view from Zygmuntowski Alley, though it is safe to say that the presence of the River Bystrzyca in Lublin's cultural landscape is not emphasized nearly enough. The purpose of this article is to assess the natural and cultural landscape value of the River Bystrzyca and guide future development with best management practices, emphasizing cultural landscape preservation and sustainable recreation.
