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 purpose of this research conducted between October 2018 and April 2019 was to determine the effect of the first and second transitional season on the nutrient profile in Ciletuh Bay. The data used in this research and directly taken from the research site were seawater quality parameters, analysis of granulometry sample and analysis of nutrient profile, while all data processing was conducted in a laboratory. The method used in this study was purposive sampling. The results of this research indicated that the nutrient profile in the first transitional season is higher than the second transition season. This is due to the introduction of organic matter into the waters. From this research it can be concluded that the first transitional season affects the concentration of nutrient in Ciletuh Bay.

Opis:: This research applied a machine learning technique for predicting the water quality parameters of Kelantan River using the historical data collected from various stations. Support Vector Machine (SVM) was used to develop the prediction model. Six water quality parameters (dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammonia nitrogen (NH3-N), and suspended solids (SS)) were predicted. The dataset was obtained from the measurement of 14 stations of Kelantan River from September 2005 to December 2017 with a total sample of 148 monthly data. We defined 3 schemes of prediction to investigate the contribution of the attribute number and the model performance. The outcome of the study demonstrated that the prediction of the suspended solid parameter gave the best performance, which was indicated by the highest values of the R2 score. Meanwhile, the prediction of the COD parameter gave the lowest score of R2 score, indicating the difficulty of the dataset to be modelled by SVM. The analysis of the contribution of attribute number shows that the prediction of the four parameters (DO, BOD, NH3-N, and SS) is directly proportional to the performance of the model. Similarly, the best prediction of the pH parameter is obtained from the utilization of the least number of attributes found in scheme 1.

Opis:: Various methods are known to mitigate or prevent scale formation in pipes, rather by chemical addition, e.g., anti-scaling substances, or physically which includes ultrasonic or nanofiltration (NF). Nanofiltration membranes have a selectivity for the multivalent charged ions, so monovalent ions will pass the membrane partly and multivalent ions will be rejected completely. Chemical addition to prevent scale formation is based on justifying water parameters such as pH, alkalinity, and concentrations of ions that form the building units of scale crystal. In order to mitigate the scaling tendency in water pumped from the Disi aquifer to Amman city along its 345 km pipeline, different studies were conducted using simulated plumbing system. This part of the study is concerned with scale mitigation using nanofiltration and addition of chemicals. Nanofiltration was applied to reduce the hardness that causes scale deposition where it rejected around 70.5% of Ca²⁺, 71.98% Mg²⁺, 7.72% K⁺, 29.0% Na⁺, 66.63% Cl^–, 86.51% NO₃ ^– , 85.72% SO₄ ^2–, and 69.85% CO₂. Increasing the concentration of some ions such as Na⁺, K⁺ and Cl^– keeping the allowable limit gave good results for scale mitigation.

Opis:: The article presents the work of the Water Treatment Plant in the town of Otoczna, located in the Wielkopolska province, before and after the modernization of the technological line. It includes the quality characteristics of the raw water and treated water with particular emphasis on changes in the quality indicators in the period 2002 - 2012 in relation to the physicochemical parameters: the content of total iron and total manganese, the ammonium ion as well as organoleptic parameters (colour and turbidity). The efficiency of technological processes was analysed, including the processes of bed start up with chalcedonic sand to remove total iron and manganese and ammonium ion. Based on the survey, it was found that the applied modernization helped solve the problem of water quality, especially the removal of excessive concentrations of iron, manganese and ammonium nitrogen from groundwater. It has been shown that one year after modernization of the technological line there was a high reduction degree of most parameters, respectively for the general iron content-99%, general manganese-93% ammonia-93%, turbidity -94%. It has been proved, that chalcedonic turned out to be better filter material than quartz sand previously used till 2008. The studies have confirmed that the stage of modernization was soon followed by bed start-up for removing general iron from the groundwater. The stage of manganese removal required more time, about eight months for bed start-up. Furthermore, the technological modernization contributed to the improvement of the efficiency of the nitrification process.
Artykuł prezentuje pracę Stacji Uzdatniania Wody w miejscowości Otoczna w województwie wielkopolskim przed i po modernizacji ciągu technologicznego. Zawarto w nim charakterystykę jakości wody surowej oraz uzdatnionej ze szczególnym uwzględnieniem zmian jakości wskaźników w latach 2002 - 2012 w odniesieniu do barwy, mętności, żelaza, manganu oraz jonu amonowego. Zanalizowano efektywność procesów technologicznych w tym przebieg procesów wpracowania złóż z piaskiem chalcedonitowym do usuwania żelaza ogólnego, manganu i jonu amonowego. Na podstawie przeprowadzonych badań stwierdzono, że zastosowana modernizacja pozwoliła rozwiązać problem poprawy jakości wody, a zwłaszcza usuwania nadmiernych stężeń związków żelaza, manganu oraz azotu amonowego z ujmowanej wody podziemnej. Wykazano, że rok po modernizacji ciągu technologicznego osiągnięto wysoki stopień redukcji większości parametrów wynoszący odpowiednio dla zawartości żelaza ogólnego - 99 %, manganu ogólnego - 93 %, amoniaku - 93 %, mętności - 94 %. Udowodniono, że zastosowany w filtrach chalcedonit okazał się lepszym materiałem filtracyjnym niż stosowany do 2008 r. piasek kwarcowy. Badania potwierdziły, że najszybciej po etapie modernizacji doszło do wpracowania złoża w etap usuwania żelaza ogólnego z wody podziemnej. Etap odmanganiania wymagał dłuższego, około ośmiomiesięcznego, czasu wpracowania się złóż. Ponadto zmodernizowanie stacji uzdatniania wpłynęło na poprawę efektywności procesu nitryfikacji.

Opis:: The development of vegetation in lotic waters, including macrophytes, is determined by diverse factors, including bottom substrate, flow velocity, and the width and depth of a channel, which are hydromorphological parameters. Macrophytes are higher plants of terrestrial origin which have undergone numerous adaptations enabling them to live in water (Stańczykowska, 1975). The aim of the study was to assess the effect of selected hydromorphological parameters of a watercourse on the species composition of macrophytes. The subject of the study was the Chechło River, a left tributary of the Vistula. The study was carried out in two adjacent segments of the watercourse, according to guidelines in the Macrophyte Index for Rivers (MMOR) and elements of the River Habitat Survey (RHS). The study revealed similar hydromorphological conditions in the two segments of the river, and the variation in the species composition of macrophytes in the two segments seems to be determined by other factors which were not the subject of the study. Among these, significant factors might include regulation works or the high water levels in the Chechło resulting from the construction of an impoundment. The plants identified in the two segments of the watercourse are species occurring commonly in Poland, preferring eutrophic waters and having a wide ecological tolerance.

Opis:: This research was intended to analyze the water quality of the Cikapundung River in Bandung City around the densely-inhabited slums and also to analyze the total number of bacteria coliform and Escherichia coli in the Cikapundung River, Bandung City. The research data was obtained by observing and performing a laboratory analysis through the assessment of environmental quality standard threshold based on the Government Regulation (PP) No. 82 of 2001. The results of laboratory analysis show that the actual condition of water quality of the Cikapundung River is overall classified as polluted, indicating 7 microbiological and physico-chemical parameters which have exceeded the quality standard such as: TSS, DO, BOD, COD, detergent/surfactant, total coliform, and Escherichia coli. In the upper part, there are 6 parameters below the quality standard, consisting of 4 physicochemical parameters and 2 microbiological parameters. In the middle part, there are 8 parameters below the quality standard consisting of 6 physico-chemical parameters and 2 microbiological parameters. In the lower part, there are 6 parameters that exceeded the quality standard consisting of 4 physico-chemical parameters and 2 microbiological parameters. The seasonal difference of parameters averagely has shown that the water quality in the rainy season is better than in the dry season. However, on average, the water sampling taken before flowing to the village has a better quality than past the village.

Opis:: This study aims to assess the water quality and determine the pollution index of the Bedadung River in the urban-area segment of Jember Regency, East Java. The sampling in the urban segment of Jember was conducted in May 2019 at five different locations, namely Slamet Riyadi Street, Mastrip Street, Bengawan Solo Street, Sumatra Street, and Imam Bonjol Street. The pollution index assessment refers to the Decree of the State Minister for the Environment of Indonesia Republic number 115 of 2003. The analysis showed that the parameters of TDS, TSS, pH, COD, BOD, NH3-N, Co, Cd, Cu, Zn, H2S, Cl–, SO4, oil and fats, MBAS, NO2-N, Fe, Pb, F, Cl2, NO3-N, phenol, and As did not exceed the quality standards. The parameters PO4, CN, total coliform, and faecal coliform were found to breach the quality standards at the 5 water sampling points. Total coliform and faecal coliform were the dominant pollutants in this segment. Therefore, the parameters of PO4, total coliform, and faecal coliform were considered as indicators of pollution arising from domestic and agricultural activities. The pollution index values for the five sampling locations ranged from 7.21 to 8.23. These scores indicate that the Bedadung River section that passes through the urban segment in Jember is classified as being in the moderately polluted category. This preliminary rapid assessment is therefore one of the considerations for the management of water quality in the Bedadung River section that passes through the urban area of Jember.

Opis:: This paper presents selected results of research connected with the development of a (3D) geostatistical hydrogeochemical model of the Kłodzko Drainage Basin, dedicated to the spatial variation in the different quality parameters of underground water in the water intake area (SW part of Poland). The research covers the period 2011–2012. Spatial analyses of the variation in various quality parameters, i.e., contents of: iron, manganese, ammonium ion, nitrate ion, phosphate ion, total organic carbon, pH redox potential and temperature, were carried out on the basis of the chemical determinations of the quality parameters of underground water samples taken from the wells in the water intake area. Spatial variation in the parameters was analyzed on the basis of data obtained (November 2011) from tests of water taken from 14 existing wells with a depth ranging from 9.5 to 38.0 m b.g.l. The latest data (January 2012) were obtained (gained) from 3 new piezometers, made in other locations in the relevant area. A depth of these piezometers amounts to 9–10 m. Data derived from 14 wells (2011) and 14 wells + 3 piezometers (2012) were subjected to spatial analyses using geostatistical methods. The evaluation of basic statistics of the quality parameters, including their histograms of distributions, scatter diagrams and correlation coefficient values r were presented. The directional semivariogram function γ(h) and the ordinary (block) kriging procedure were used to build the 3D geostatistical model. The geostatistical parameters of the theoretical models of directional semivariograms of the water quality parameters under study, calculated along the wells depth (taking into account the terrain elevation), were used in the ordinary (block) kriging estimation. The obtained results of estimation, i.e., block diagrams allowed us to determine the levels of increased values of estimated averages Z* of underground water quality parameters.

Opis:: The study shows the biodiversity of Utricularia australis from western to northern regions of Ukraine. The environmental conditions of Ukraine are favourable for the spread and formation of phytocenosis involving U. australis, especially on thermoclimatic, cryothermal and continental scale. A broader range of the species’ relation to humidity has been recorded. The research outcome shows the existence of the species in conditions from shallow, parched reservoirs to deep water habitats which allows the species to withstand temporary drying of reservoirs in summer periods. The resilience of U. australis to some water quality parameters, including nitrogen, phosphorus, iron content, colour, pH and organic contamination was higher than in previous studies and Tsyganov’s ecological scales. Thus, due to its wide range of tolerance to the majority of environmental factors, U. australis tends to spread in contemporary climatic conditions in Ukraine. Considering that the species has category “vulnerable” in the country and is listed in the red data book of Ukraine, its conservation status is likely to be revised further.

Opis:: The pollution of rivers is an important issue because the utilization of polluted water has a direct effect on the health of people and other living beings, economy, etc. Sediments represent a very suitable indicator for monitoring and detecting pollution sources of river waters. The aim of this study is to analyze the contents of selected metals in the sediments of the rivers Likova, Kumanova and Pçinja rivers. The water samples were taken in June 2014 from six sampling stations. Several physicochemical parameters of rivers were determined and the contents of twenty-two metals was indicated in the sediment samples taken from these rivers. The obtained physico-chemical quality of the water from these rivers resulted in classification to the first/second category. The sediments were mostly polluted by Al, Ca, Na and Mg. The metals that exceeded the Dutch standard were: Ba, Ni, Zn, Cr and Cu. The order of metals in sediments was as follows: Fe > Al > Ca > Na > Mg > K > Mn > Ba > Sr > Cr > Zn > V > Ni > Cu > Pb > Li. The study results reveal a mild pollution in rivers caused by urban, agricultural and industrial activities.

Opis:: The article describes modern anthropogenic load on the surface water of the Southern Bug River Basin in a changing climate. The main water users-pollutants of the Southern Bug River Basin in Vinnytska and Mykolaivska regions were identified. The water quality of the surface water of the Southern Bug River in time and space (along the river stream) was analyzed. The water quality of the Southern Bug River was assessed by complex indices for different water users. In order to assess water quality, it is recommended to use complex indices that take into account the effect of the total action of pollutants. The self-purification potential and capability of restoration in space (along the river stream) of the aquatic ecosystem of the Southern Bug River was established for 2019. The results of the study allow us to state that the use of surface water of the Southern Bug River Basin for drinking, fishery, cultural and recreational needs is related to certain environmental risks. It is recommended to carry out the environmental protection measures aimed at adjusting the priorities of economic activity, reduction of wastewater discharge and increase in the water content of the river by regulating the operation of energy complexes.

Opis:: In this paper, the regression analysis technique is applied to a large water quality dataset for the Sitnica River in Kosovo. It has been done to assess the correlation between water quality parameters. The data are generated by a wireless sensors network deployed in Sitnica. A regression analysis is applied to four water quality parameters: temperature, dissolved oxygen, pH, and electrical conductivity. The correlation between each pair of parameters has been assessed by using the WEKA software package, which is a popular time-saving tool for data analysis in distinct domains. The data are pre-processed to exclude out-of-range values and then the assessment of correlation for the pairs of parameters is applied. In comparison to other pairs of water quality parameters, the results show that dissolved oxygen and electrical conductivity correlate particularly closely with temperature. Regression equations of these two pairs of parameters may provide inferred information on dissolved oxygen and electrical conductivity about the Sitnica River.
