Korzkiewka stream
Opis:: The aim of the paper was the identification and assessment of the area of anthropogenic impacts on water quality in the catchment of the Korzkiewka stream flowing through the areas of the Malopolska region. Analyses of physicochemical indices revealed that waters along the whole length of the stream qualified for below good status due to the exceeded EC and nitrate nitrogen concentrations. It was found that among 21 analyzed physicochemical indices, statistically significant differences occurred for 5: total dissolved solids, SO₄^2-., Mg²⁺, K⁺ and water pH. In the headwaters section values of four salinity indices were significantly higher in relation to the other part of the stream. Assessment of anthropogenic factors affecting the catchment water resources conducted on the basis of unitary and percent indices revealed that the dominant category shaping the physicochemical status of the Korzkiewka stream water is municipal economy. The intensity of the influence of the factors from this category was from medium to very high, while in case of sewage discharged through the sewage network, even to outlier intensity. Forestry and agriculture exerted medium pressure, whereas the factors from the industry category had hardly any influence on water in the stream.

Opis:: Sustainable use of waters requires not only determining the amount, but primarily the quality of the available water resources and developing a long-term programme of their protection. The analysis of the Łososina river water in the area of Tymbark city was presented in the paper. The water was tested in a view of the requirements as the natural fish habitat and its potential use for people supply in potable water. The river water samples were taken in 2014 at randomly selected dates, once a month in 5 measurement points. 21 physicochemical indices were assessed in the samples. The assessment of the Łososina river water quality was made on the basis of the results of both: on site and laboratory testing, which were compared with the Regulation of the Minister of Environment of 23 October 2014. The utility values were assessed on the basis of the Regulations of the Minister of Environment of 27 November and 04 October 2014. The analysis of the results demonstrated that the Łososina river water met the requirements of quality class I water in points 1, 2 and 3. Below Tymbark the Łososina river water was polluted, so due to high BOD5 in points 4 and 5, and phosphate concentrations in point 4, it was classified as class II, i.e. good state. Pollution coefficients computed according to Burchard and Dubaniewicz classify the Łososina river water as clean along the whole investigated stretch. Below Tymbark city (points 4 and 5) the Łososina river water cannot be used for drinking water supply because of high BOD5 and iron concentrations. In the other points it could be used for water supply following appropriate physical and chemical treatment. The water does not meet the requirements for salmonid or cyprinid fish along the whole stretch because of high nitrite concentrations, except point 3, where the Łososina river water provided a proper natural habitat for carp.

Opis:: Hydrochemical research was conducted in 2011 at three measurement-control points on the Sztoła river, a left-bank tributary to the Biała Przemsza river. Water temperature and pH, dissolved oxygen concentration, oxygen saturation and electrolytic conductivity were measured directly in the field. 11 selected physicochemical indices of the Sztoła surface water were assessed in the laboratory. The analysis of the research results revealed that the water of the Sztoła along the analyzed river reach was first class quality. The analysis of water usable qualities proved that at point 1 it can be used for water supply after high-performance physical and chemical treatment, whereas at other points after a typical physical and chemical treatment, due to high manganese concentrations. Water does not meet the requirements of natural habitat for the Salmonoid fish only at point 1 because of exceeded standard values for nitrites. The Cyprinid fish have the proper habitat conditions along the examined river reach. Among 15 analysed physiochemical indices of water, 7 were statistically higher in the lower course, but they did not affect worsening of the Sztoła river water quality. Greater water pollution in the central and lower river reach is caused by the anthropogenic pressure connected mainly with the operations of extraction industry in the catchment.

Opis:: The results of five-year (2008–2012) hydrochemical research of the Poprad river, the right bank tributary to the Dunajec, were analyzed in the paper. The Poprad, 167 km long and with the catchment area of 2077.3 km², flows for over 100 km through the territory of Slovakia, along the length of 31.1 km is a transboundary river, whereas its 31.0 km long reach is situated in Poland. Concerning its abiotic character, it is an eastern upland river of type 15. The research was conducted in three measurement-control points: 1) located in Leluchów on the Polish-Slovak border at 61.1 kilometer of the river course, 2) in Piwniczna-Zdrój – 23.9 km and 3) in Stary Sącz – 2.9 km before the Poprad outlet to the Dunajec. 21 physicochemical indices and 2 microbiological indicators were assessed in the water samples once a month using referential methods. The paper assesses changes of water quality classes and its usable values along the analyzed Poprad river reach. Moreover, statistical differences between the values of individual indices assessed in various measurement-control points were estimated by means of Mann-Whitney U nonparametric test. On the basis of the conducted analyses of the empirical data it was stated that due to the physicochemical indices, water quality along the whole length of the analyzed river reach was good (class II) – in points 1 and 3 it was determined by mean concentration of total suspended solids, whereas in point 2 COD-Mn values.
