Opis:
This paper presents the analysis and evaluation of the impact of clean sewage on the water in the Mordarka river, in the period 2012–2015. The analysis was conducted based on the collected and statistical research: the amount and composition of the purified sewage discharged to the receiver. The following pollution indices were tested: total suspended solids, BOD5, COD, total nitrogen and total phosphorus. On the basis of the obtained results it was concluded that the amount of purified wastewater discharge to the Mordarka river, did not contribute to the degradation of the water quality in that period of time. Moreover, the level of indicators: total suspended solid, BOD5 and COD did not exceed the limit values from the regulation, which confirmed the effective protection of water quality in the Mordarka river. However, because of the high concentration of biogenic compounds in the purified wastewater effluents, the river is prone to eutrophication process.

Opis:
The work concerns the modernization of the Water Treatment Plant, the objective of which was to improve the quality of recipients; life by counteracting water deficits and ensuring a stable supply of water with appropriate pressure and quality, in accordance with the requirements of applicable regulations. Installing modern control and measuring equipment, as well as modern devices during the modernization of the facility, will significantly reduce electricity consumption, which will realistically minimize the operating costs. The article describes in detail what the modernization of the water treatment plant was like and what effects of water treatment from the quaternary aquifer were obtained. After the completed modernization of the plant, the County Sanitary and Epidemiological Station gave a positive opinion on all materials and devices used in the modernization of the WTP and agreed to supply the existing water supply with purified water.

Opis:
An effect of factors determining water quality in the water supply network in Kraków is assessed. The data collected over a four-year research period included quality parameters of water taken from the water distribution system in the period between 1 January 2011 and 31 December 2014. In the analysis the supply zones of four municipal water treatment plants in Krakow were considered. The selection of 29 water sampling points within the supply area allowed comparing water quality with respect to operational and technological aspects. Factor analysis enabled 4 components explaining correlations between tap water quality variables to be distinguished. It follows from the research performed that the obtained factors applied to 77% of overall water variability. The highest share was assigned to factor 1 that explained 32% of the chemical composition of water under consideration and was correlated with calcium, conductance, nitrates (V), magnesium and to a moderate extent with Σ THM (with negative sign).

Opis:
The purpose of this paper was to assess the influence of the city of Przemyśl on the quality of water in the San River. The water analysis carried out by the Voivodeship Environmental Protection Inspector in Rzeszów as part of the operational monitoring in 2014 and in 2017 was used in the study. The concentrations of selected physicochemical indicators determined in two measurement and control points located above and below the city of Przemyśl were taken into account. For each water quality indicator, the minimum and maximum values were determined and the arithmetic averages from the research period were calculated. In addition, the regularly performed indicators were subjected to a detailed statistical analysis. Box plot graphs show the extreme values, the median and the interquartile range. Water quality has been assigned to the appropriate class and category of surface waters. Selected specific pollutants and priority substances in the river water were also analysed. Only the concentration of benzo(a) pyrene at the measuring points did not comply with the environmental quality standards. It was found that the city of Przemyśl has a small influence on the quality of water in the San River. Although there was a deterioration of water quality at the measurement and control point below the city, its class and category did not change.

Opis:
Rational use of surface and underground waters leads to a reduction in their consumption, which is currently one of the fundamental tasks in the field of the conservation of waters, in its broad sense. This includes also the utilisation of water from additional sources, such as e.g. precipitation water. The paper presents an analysis of the quality of rainwater outflowing from the roofs of garage buildings of the Park Authority of the Roztocze National Park. The results of analyses presented in the paper indicate a favourable composition of rainwater that meets the norms defined for water for human consumption. In the waters under analysis, exceeded levels were noted for ammonia, manganese and biological factors, but these do not preclude the use of the waters for household purposes. Rainwaters at the Roztocze National Park can be used for car washing, for the irrigation of green areas, or for toilet flushing. Such utilisation of rainwaters can largely contribute to a reduction of the use of high-quality underground waters.

Opis:
The dynamics of hydrochemical parameters of surface waters from the upper, middle and lower reaches of the river was analyzed. On the basis of the analysis of temporal and spatial monitoring data, a comprehensive assessment of the environmental status of the Inhulets river (Ukraine) waters by hydrochemical indicators was carried out. The study performed a comparative analysis of the river water quality assessment using different methods: an integrated assessment based on the calculation of water pollution indexes, pollution rate. A result of the evaluation of water quality in certain classes: in terms of ammonium ions and BOD5 – III quality class, the water is slightly polluted; phosphate content – V quality class, water is very low in the bottom; according to the content of suspended solids, in phosphates and BOD5 – III class of water quality, water is polluted; by a concentration of chlorides – V class of quality, degree of purity – very dirty; the value of suspended solids and chlorides – III class; in terms of the sulfate content – IV class. In general, the very excessive concentration of substances in the middle course remains stable, the environmental state is poor (quality class IV).

The article describes the steps for organizing and conducting the ecological monitoring of surface water in order to shift Ukraine to the European standards in the field of water use and protection. The main water users-pollutants of the Western Bug River basin in the Lviv region were identified. The results of the water samples taken from the control bodies in 2018 were analyzed. A promising way to improve the work of the water basin management of the Western Bug River was proposed.

Opis:
On the basis of the analysis of wide temporal monitoring data, a forecast of the integrated hydrochemical indicators of the waters of the Inhul river (Ukraine) was carried out. The performed analysis was also the basis for the determination of a mathematical model of natural fluctuations of the indicators studied. The determined sinusoidal dependence of the integrated water quality indicators allowed determining the average time of fluctuations concerning the processes of self-organisation of river waters. In practice, the developed mathematical models may constitute a valuable support and supplement to the existing models in the field of prediction of self-organization processes of river waters. They may also contribute to even more effective minimization of undesirable effects of anthropogenic impact on aquatic ecosystems.
