Opis:
The implementation of the European Union Water Framework Directive required a number of tasks to be fulfilled: classifying the various water bodies into different types, defining reference conditions for each of the types and assessing their ecological quality status – this last is based on biological, hydromorphological and physicochemical quality elements of the ecosystem. The paper presents an attempt to estimate reference values in selected areas of Polish coastal and transitional waters as well as in an open sea area following WFD principles. The preliminary eutrophication assessment showed all the assessed areas to be eutrophication problem areas.

Opis:
The aim of the article is to determine the role of renewable energy sources (RES) in the development of tourism in the areas which are famous for their natural and cultural values (protected areas). The example discussed in the article is the center of religious and pilgrimage tourism in Kodeń (Lubelskie voivodship, bialski poviat). The analyzed tourism center is located in the Bug River Protected Landscape Area and the area of the Natura 2000, the Middle Bug River Valley. It seems very significant to point out: (1) the role of RES in the development of tourism in the areas, which are famous for their natural and cultural values; (2) whether or not the production of energy in small-scale RES installations (up to about 200 kW) improves the quality of tourist services in protected areas and allows the creation of ecological quality of these services and (3) which RES are the most appropriate for use in the tourist facilities located in protected areas.

Opis:
This work presents rules and results of classifications of hydromorphological status of watercourses used presently in Europe. The Water Framework Directive introduced an obligation to monitor hydromorphological elements of rivers, which include hydrological regime, river continuity and bed morphology. European standards require somewhat different quality indicators and the way of their assessment for such investigations. Classification of status and ecological potential shall include categories and types of rivers, however, the methods existing so far do not provide such a distinction. Assessment of much differentiated features and attributes, as well as the requirement of presenting the outcome in EQR form, within limits from zero to one, cause that all the studied parameters, which are very diverse, must be conveyed to numerical form. The MHR method takes into account the above conditions and proposes a classification which includes limit values for five classes of status and four classes of ecological potential. It assumes limit values of classes lowering from natural watercourses through heavily modified to artificial.
W pracy przedstawiono zasady i wyniki stosowanych dotychczas w Europie klasyfikacji stanu hydromorfologicznego cieków. Ramowa Dyrektywa Wodna wprowadziła obowiązek monitorowania elementów hydromorfologicznych rzek, do których zaliczono reżim hydrologiczny, ciągłość rzeki oraz morfologię koryta. Normy europejskie określają wymagane w takich badaniach nieco odmienne wskaźniki jakości i sposób ich oceny. Według klasyfikacji stanu i potencjału ekologicznego powinny być uwzględnione kategorie i typy rzek, natomiast według dotychczasowych metod nie ma takiego rozróżnienia. Ocena bardzo zróżnicowanych wskaźników i atrybutów oraz wymóg prezentowania wyniku w formie EQR w granicach od zera do jedności powoduje, że wszystkie badane parametry, które są bardzo zróżnicowane, muszą być doprowadzone do formy liczbowej. W metodzie MHR uwzględnia się powyższe uwarunkowania i proponuje klasyfikację, zawierającą wartości graniczne pięciu klas stanu oraz czterech klas potencjału ekologicznego. Zakłada się w niej, że wartości graniczne klas zmniejszają się od cieków naturalnych poprzez silnie zmienione do sztucznych.

Opis:
The paper aims at presentation of the effect of changes in the catchment area management on the value of water quality physicochemical indices along the length of the Iwoniczanka stream, which flows through Iwonicz-Zdrój, one of the oldest health resorts in Poland. Analyses of 14 water quality indices were conducted from November 2013 to May 2014 in five measurement points: two situated in the upper course of the stream – in forest areas, two located in the area of Iwonicz-Zdrój town, and one below the rural built-up area. On the basis of the conducted data analysis it was found that the mean values of pH, electrolytic conductivity, sulphates, calcium, total iron and manganese were increasing with the course of flowing water, as evidenced by the water enrichment in substances which had their sources in built-up areas. On average, the highest values of biogenic indices and chlorides but the lowest values of oxygen indices were registered immediately below the location of drain collector from the closed sewage treatment plant, which resulted in pollution of the analysed stream bed with the substances previously drained from the treatment plant. Water flowing through the forest areas had the maximum ecological potential in the built-up areas and due to phosphate concentrations it was classified to class II and then, due to self-purification, returned to the physicochemical parameters appropriate for class I water. The conducted hydro-chemical tests confirmed a significant negative effect of built-up areas on the quality of the flowing waters.

Opis:
The extensive nature of natural resource use in the Siret River basin in recent years has led to a significant depletion of its water resources and deterioration of the ecological state of surface waters. The following paper presents the results of assessing the degree of water pollution of the Siret River. A number of biotic water quality indices were used for this purpose. In particular, the Trent Biotic Index (TBI) and the Biological Monitoring Working Party Index (BMWP), both of which use the density ratio of different macroinvertebrate taxa in the aquatic communities, and the Pantlé and Bucca saprobility index, which uses the absolute density and saprobility of indicator species of aquatic organisms. A comprehensive assessment of the aquatic ecosystem of the watercourse was carried out using the water pollution index (WPI). The biological indices were calculated on the basis of data on zooperiphyton communities formed on an artificial fibre media of the «VIYA» type. The VIYA fibre carrier was used for more accurate determination of the species composition and quantitative characteristics of zooperiphyton communities in the studied river sections. The TBI index ranged from 5 to 6 (which corresponds to a water quality assessment of 'satisfactory'). The BMWP index ranged from 8 (very poor) to 32 (good), and the saprobicity index from 1.52 to 1.95 (good water quality). The WPI index at the control sites in the Siret River ranged from 4.6 (which corresponds to a water quality assessment of 'polluted') to 8.1 (which corresponds to a water quality assessment of 'extremely polluted'). Significant differences in the results of the assessment by different biotic indices indicate that these indices cannot be used as indicators for an exhaustive assessment of water quality using zooperiphyton. They can only be used as relative indicators for comparing the state of water pollution at different locations. The values of hydrochemical indicators of water quality at two observation posts of the river were analysed. The maximum permissible concentrations of nitrite ions, ammonium ions and suspended solids in the control sections of the river were found to be exceeded.

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.

Opis:
Estuaries are coastal areas that have a fairly high fertility rate. This region can be said to be fertile because it is influenced by such physical factors as temperature, turbidity, light, and current as well as such chemical factors as salinity, dissolved oxygen, pH, and nutrient content. The estuary of the Banjar Kemuning River is a coastal area with a lot of human activities, and it is close to the mainland, causing the change in the nutrient content in the waters. The nutrient content in the waters is closely related to the phytoplankton abundance, as the higher the nutrient content in the waters, the greater the phytoplankton abundance and the chlorophyll-a content. The level of chlorophyll-a content in the waters can indirectly be used as an indicator of the phytoplankton abundance, which can determine the level of fertility of these waters. The purpose of this study was to determine the relationship between the phytoplankton abundance and the chlorophyll-a content in the estuary of the Banjar Kemuning River. This study is observational research with data analysis using linear regression, simple correlation (Pearson), and ANOVA. In addition, the data collection was carried out by purposive random sampling at predetermined points of stations. The results of this study indicated that the phytoplankton abundance and the chlorophyll-a content at the estuary of Banjar Kemuning River during different months were significantly different (P < 0.05). The average phytoplankton abundance during the study was 19,256 cells/L, 19,044 cells/L, and 22,613 cells/L, while the average chlorophyll-a content during the study was 0.958 µg/L, 0.998 µg/L, and 1.167 µg/L. The conclusion was drawn that there is a difference between the phytoplankton abundance and the chlorophyll-a content each month and classified into high correlation.

One of important factors of attractiveness of a region is its natural environment, namely a set of natural elements which are of interest to a tourist. In terms of economy, it is a source of raw materials and energy, it ensures geographical space, business opportunities and a place to live and relax. The aim of the research included in this article is to indicate the possibility of using synthetic measurement to recognize spatial disparities of the natural environment on the basis of selected diagnostic features of 102 municipalities of the Świętokrzyskie Voivodeship. The data presented in this article refer to 2009, 2012 and 2015 and come from the Local Data Bank. The following variables were selected: the total use of household water per one inhabitant, the distribution network per 100 km2 - water pipe system, the distribution network per 100 km2 – sewage system, woodland area, areas protected by law, protected monuments. The elements indicated refer to entities which function and operate in a territorial unit. The methods presented enable us to identify areas of human life (or human impact on the environment) of higher/lower efficiency (which depends on the level of synthetic measure) and, then, programme their support from public funds within the framework of the regional policy.

Opis:
The paper aimed at determining the effect of treated sewage discharged from a sewage treatment plant, modernized in 2007–2008, on the quality of the receiving water – the Breń river. The mechanical-biological sewage treatment plant is situated in the northern part of Dąbrowa Tarnowska town (Malopolskie voivodship). The treated sewage is disposed of by means of a collecting pipe to the Breń river, which abiotically is a lowland sandy stream, type 17. The hydrochemical analyses were conducted monthly, from May 2014 to April 2015 in three measurement points. The first and the third were situated on the Breń river, 30 m above and 400 m below the treated sewage outlet respectively, whereas the second one was on the outflow collecting pipe from the sewage treatment plant. In the analysed water, 17 physicochemical water quality indices were determined by means of reference methods. On the basis of the data analysis it was found that pollutant concentrations in the treated sewage discharged into the Bren river did not exceed the values stated in the water permit and only sporadically did not meet the requirements stated in the Regulation of the Minister of Environment regarding ammonium nitrogen concentrations in the winter-spring period. Slight dynamics of seasonal changes of physicochemical indices values in the treated sewage evidences a high proficiency of the sewage treatment plant operation, irrespective of the air or water temperature. The treated sewage affected the increase in 12 from among 17 analysed physicochemical indices in the Breń river, of which the dependencies were statistically significant in 8 cases. BOD5 and ammonium nitrate caused a change of water quality class from I to II, and in case of phosphates a decline of ecological state from very good to below good. Despite a negative effect of the sewage treatment plant, the water quality state in the Breń river would be much worse if untreated municipal waste flowed into the receiving water.

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.
