Opis:
Rivers are considered as one of the main resources of water supply for various applications such as agricultural, drinking and industrial purposes. Also, these resources are used as a place for discharge of sewages, industrial wastewater and agricultural drainage. Regarding the fact that each river has a certain capacity for acceptance of pollutants, nowadays qualitative and environmental investigations of these resources are proposed. In this study, qualitative investigation of the Talar river was done according to Oregon Water Quality Index (OWQI), National Sanitation Foundation Water Quality Index (NSFWQI) and Wilcox indicators during 2011–2012 years at upstream, midstream and downstream of the river in two periods of wet and dry seasons. According to the results of OWQI, all of the values at 3 stations and both periods are placed at very bad quality category and the water is not acceptable for drinking purposes. According to NSFWQI, the best condition was related to the upstream station at wet season period (58, medium quality) and the worst condition was related to the downstream in wet season period (46, very bad quality). Also the results of Wilcox showed that in both periods of wet season and dry season, the water quality is getting better from upstream station to the downstream station, and according to the index classification, the downstream water quality has shown good quality and it is suitable for agriculture.

Opis:
Surface water resource, such as river, is constantly contaminated by domestic and industrial pollutants. In order to properly manage the water resource, a composite index for water quality assessment, such as water quality index (WQI), has been designed to monitor and evaluate the properties of surface water. However, this index is quite subjective in terms of determination of relative weights. A principal component analysis (PCA) can be used to reduce the dimension and subjectivity of water quality variables. The purpose of this study was to implement the use of hybrid PCA and WQI methods to assess and monitor the water quality of the Bengawan Solo River, which is located in Java Island, Indonesia. The result suggested that COD, BOD, TSS, TDS, nitrate, nitrite, and ammonia were the main factors that determine water quality of the Bengawan Solo River. Furthermore, it was revealed that most samples from the river showed water quality status as slightly polluted. In addition to this, the seasonal variation of the PCWI values indicated a significant increase of water pollution in the Bengawan Solo River per year.

Opis:
Fountains are decorative elements that improve the attractiveness and visual qualities of urban environments. They can give refreshment to residents on a hot, sunny day. Despite the prohibitions on bathing in these facilities people often have contact with fountain water. It should be emphasized that poor quality of water from fountains can be dangerous for human health. This study was aimed at evaluating microbial contamination of water in Krakow fountains (fountain from Szczepański Square, fountain on the Groble Square, “Chopin” fountain near the philharmonic, “Stone” fountain on the Maria Magdalena Square and the fountain on the Main Market Square). Microbiological analyses were conducted to determine the total number of microorganisms at 36±2ºC after 48 hours (mesophilic bacteria) and the total number of microorganisms at 22±2ºC after 74 hours (psychrophilic bacteria). In addition, the coliform bacteria, Escherichia coli and Closridium perfringens were also examined. The results have shown a high degree of microbiological contaminants in the tested water samples. The lowest contamination of water was observed in the fountain on the Szczepański Square and in nozzle water from the fountain on the Groble Square. The highest numbers of bacteria were found in “Stone” fountain at the Maria Magdalena Square.

Modelowanie matematyczne systemów dystrybucji wody jest coraz częściej wykorzystywane w procesach automatycznego sterowania i zarządzania w przedsiębiorstwach wodociągowych. W pracy zaprezentowano model hydrauliczny fragmentu systemu zaopatrzenia w wodę eksploatowanego przez Górnośląskie Przedsiębiorstwo Wodociągów w Katowicach, powiązany z modelem transportu masy i kinetyką reakcji pierwszego rzędu zużycia chloru oraz powstawania trihalometanów. Zaproponowany model został pozytywnie zweryfikowany wynikami pomiarów. Większość odchyleń zawartości chloru pozostałego i sumy THM od wartości zmierzonych nie przekraczała 30%. Potwierdzona zatem została jego przydatność do prognozowania zarówno zawartości chloru wolnego, jak i sumy THM w wodzie podczas jej transportu do odbiorców. Przeprowadzone symulacje umożliwiły dodatkowo zidentyfikowanie odcinków sieci, w których występowały lokalne niedobory chloru pozostałego w wodzie.
Mathematical modeling of water distribution systems has become an increasingly frequent mode made use of in the processes of automatic control and management in water supply systems. The paper presents the hydraulic model of a part of the water supply system that is combined with the mass transport model and with the kinetics of the first-order reactions of chlorine depletion and trihalomethane (THM) formation. The model proposed was positively verified via measured data. The majority of the deviations of residual chlorine content and THM sum from relevant measured values did not exceed 30%. These findings substantiated the reliability of the model when applied to forecasting not only the free chlorine content but also the THM sum value in the water during transport to the users. Computer simulations enabled additional identification of the pipe sections where a local deficiency of residual chlorine in the water occurred.

Opis:
Water is one of the most important natural resources for all living organisms, including humans. Water consumption is increasing over the years as a result of the increase in the number of people, and at the same time, the causes of pollution of surface water sources increase. Water pollution is one of the most important causes of diseases and the transmission of infection to the organisms that use it. Also, the quality of agricultural crops is linked to the quality of the water used for irrigation. As a result, there was a need to monitor and evaluate the main water sources to maintain the quality of their water suitable for use by humans and other organisms. As is well known, it is difficult to evaluate the water quality of large samples with concentrations of many parameters using traditional methods, which depend on comparing experimentally determined parameter values with current standards. As a result, over the past century and the present, many methods of assessing water quality have emerged. This research aims to introduce the most important indices of water quality used at present to assess the quality of surface water for drinking and irrigation purposes, as well as the history of these methods and their development over time and their most important advantages, in addition to a group of the most important research that used these methods during the past few years.

Opis:
W pracy omówiono doświadczenia warszawskich wodociągów w zakresie wprowadzania i eksploatacji monitoringu jakości wody pracującego w systemie on-line. Systemem tym objęto Wodociąg Północny, uzdatniający wodę infiltracyjną ujmowaną spod dna Wisły, oraz dwie stacje uzdatniania wody podziemnej, tj. "Radość" i "Falenica". Ciągłym monitoringiem została objęta woda ujmowana i wprowadzana do sieci miejskiej, a także woda w newralgicznych punktach układu technologicznego. Zakres oznaczanych wskaźników jakości wody był następujący: temperatura, pH, mętność, absorbancja w UV oraz zawartość tlenu rozpuszczonego. Dotychczasowe doświadczenia potwierdziły potrzebę monitorowania on-line jakości wody, dzięki czemu została zwiększona dyscyplina eksploatacyjna, a w okresach ekstremalnych, np. spływów powodziowych w rzece, zakład dysponuje aktualnymi informacjami o zmianach jakości ujmowanej wody oraz prawidłowości przebiegu poszczególnych procesów technologicznych. Przewiduje się dalszą rozbudowę systemu o układ do ciągłego oznaczenia stężenia azotu amonowego i ogólnego węgla organicznego. Doświadczenia Wodociągu Praskiego potwierdzają celowość prowadzenia monitoringu jakości wody w systemie on-line, co przyczyniło się do prawidłowej kontroli przebiegu procesów technologicznych, a w konsekwencji do zachowania wymaganej jakości wody uzdatnionej. Zastosowanie monitoringu on-line nie jest równoznaczne z zaprzestaniem bieżącej kontroli jakości wody w laboratorium.
The experience gained by the Warsaw Waterworks staff whilst implementing and operating the on-line water quality monitoring system is described in detail. The system covers the Northern Water Distribution Unit (providing treatment and supply of infiltration water drawn from the bottom of the river Vistula), as well as two groundwater treatment plants (Radość and Falenica). Continuous monitoring is carried out for the quality of the water taken in and set to the municipal network, as well as for water quality at the critical points of the technological system. Determined are temperature, pH, turbidity, UV absorbance and dissolved oxygen content. On-line water quality monitoring was found to be particularly useful during, e.g., high-water episodes, in that it provided current information on any change in the quality of the taken-in water or in the efficiency of particular technological processes. Further developments of the monitoring system include continuous determinations of ammonia nitrogen and total organic carbon concentrations. The experience gained by the staff of the Praski Water Distribution Unit also substantiates the usefulness of the on-line water quality monitoring system, as it enables an effective control of the technological processes involved and consequently the maintenance of the desired quality of the treated water. The implementation of the on-line water quality monitoring system does not eliminate current water quality analyses at the laboratories.

Opis:
This study aims to prove the type and abundance of macrozoobenthos are affected by the physico-chemical condition of the habitat so that it can be used as a bioindicator in assessing river water quality with a case study in the Upstream of Citarum River. The method used in this study consists of two stages, namely determining the status of river quality with pollution index and determining the components to see the relationship of the water quality parameters to the abundance of macrozoobenthos with principal component analysis. On the basis of these studies, the results were that at the location of the study status of the river quality is slightly polluted and mildly polluted. For the slightly polluted status Corbicula sp. was used as the dominant macrozoobenthos parameter with the parameters of dissolved oxygen, organic carbon and N-O in the clay-dominated sediments. In turn, for the river areas with mild pollution, Enallagma sp., Tubifex sp., and Chironomous sp. were used as bioindicators and they have a relationship with the parameters of nitrate, TSS, and P-total.

Opis:
Open cast mines can cause several modification of environment, as like decrease of groundwater level, soil modifications, noise, changes of river discharge and others. The year 2009 was the last year of mine waters discharge from Lubstów mine (Wielkopolska province) to Noteć River, which caused increase of river discharge for approximately 17%. The paper presents results of two years of studies on impact of mine waters from brown coal open-pit mine on lowland river. Most important water quality parameters like pH reaction, conductivity, sulphates and nutrients were analysed in all sites. Biological indication methods (MTR, IBMR, RI and others) based on aquatic plants (macrophytes, algae, mosses, liverworts) were used in studies to evaluate possible water quality changes below mine water discharge. Additionally, indices describing biological diversity (Shannon-Wiener W, Simpson D, uniformity J) were calculated using data from standard Mean Trophic Rank survey. In all three sites domination of several aquatic taxa was observed. Most frequent taxa were Elodea canadensis and Berula erecta. Other taxa often present in Noteć River were Spirodela plyrhiza, Sparganium emersum, Sparganium erectum, Mentha aquatica and Symphytum officinale. Results of studies were used for statistical analyses of Friedman ANOVA. Obtained data showed, that according to analysed water quality parameters as like, pH reaction, conductivity, total phosphorus, nitrates and others, changes of water quality were negligible. Results obtained using macrophyte indices for estimation of water trophy and ecological state confirmed results of chemical measurements. According to ANOVA, statistically significant relations were found for macrophyte biological diversity indices among surveyed river sites (χ2 = 8.40; p = 0.015). It was also confirmed by Kendall coefficient W = 0.84. The highest biological diversity was observed in site 1 situated above mine waters discharge and it was decreasing in sites 2 and 3. For the Shannon-Wiener (H’) index average coefficients were respectively 0.29 and 0.23, thus precise interpretation of these relation is difficult and to some extent could depend on other factors, eg. shading. Results of studies showed, that according to measured water quality parameters mine waters discharge from deep seated drainage did not caused significant changes of Noteć river water quality.

Opis:
This study aims at assessing and interpreting groundwater quality using statistical techniques in Otuoke and environs, Bayelsa State, Nigeria. Fourteen (14) groundwater samples were collected in the rainy season and analyzed for their physico-chemical and heavy metal contents. Heavy metals were analyzed using Atomic Adsorption Spectrometer. Assessment for drinking purposes revealed that the water is predominantly acidic, with iron and manganese contents exceeding regulatory guidelines in most locations. All other parameters were within WHO and NSDWQ regulatory limits for safe potable water. Water Quality Index revealed that over 73% of the groundwater in the area (11 samples) had good to excellent quality; while the remaining 27% of the groundwater (3 samples) have poor to unsuitable quality for consumption. Assessment of water quality for irrigation purposes was achieved using Sodium Adsorption Ratio (SAR), Potential Salinity (PS), Permeability Index (PI), Sodium percentage (Na%), Kelly’s ratio (KR), and Magnesium Adsorption Ratio (MAR). On average SAR (4.19), PI (68.51%), MAR (37.45%) and PS (0.77) revealed excellent water quality, whereas Na% (66.46%) revealed doubtful water quality while KR (2.00) revealed unsuitable water quality. Using Piper and Stiff diagrams, hydrochemical facies defined from groundwater in the area includes; Na+K – Cl facies; Na+K - Mg – Cl facies; and Na+K - Ca – Cl facies. Gibb’s diagrams revealed that the dominant control on the hydrochemical facies and overall groundwater quality in the area has been attributed to precipitation and chemical weathering of subsurface rocks. Various ionic ratios including Mg/Ca (0.642), HCO3ˉ/Cl (0.040), (Na+K)/Cl (7.026) and Cation Exchange Values (-6.026) revealed low salt inland origin with respect to provenance. Pearson correlation matrices showed both positive and negative inter-relationships between the physico-chemical and heavy metals in groundwater within the study area. This study has proven the effective use of water quality index as a tool for defining the overall quality of water in Otuoke and its environs, along with hotspots that needs immediate attention. The results could also serve as a decision making tool that will aid in establishment of treatment facilities to improve the quality of water in the study area.

Human activities may cause degradation of water quality. For monitoring purpose, it is necessary to know the level of pollution that occurs in water in order to sustain the function of the aquatic ecosystem. The purpose of this study was to determine the level of water pollution of Menjer Wonosobo Lake based on the physical, chemical, and biological parameters to evaluate the best function of the water to support the human activities. The study was conducted for three months (July to September 2020). Water sampling was carried out at seven stations; then, the measurement results were compared with the water quality standards based on Government Regulation No. 22 of 2021. Determination of water quality was carried out using the STORET method. The results showed that there were 7 parameters that exceeded the water quality standards, namely TSS, BOD, COD, DO, N, P and Coliform. The status of water quality was at a moderately polluted level and only functions for the needs of category 3, i.e. for freshwater fish cultivation, for irrigating plants, and or other purposes. Therefore, it was necessary to manage Menjer Lake to improve its water quality.

The main purpose of the study was to evaluate water quality of the Supraśl river and identify its main pollution sources. On the river and its tributaries, 8 control points were selected, located near Krynica, Gródek, Nowosiółki, Zasady (mouth of the tributary Sokołda), Supraśl, Nowodworce, Dobrzyniewo (mouth of the tributary Biała) and Dzikie. The control points were selected in such a way as to take into account the impact of major point sources of analyzed components located along the river and its main tributaries on water quality in the main stream catchment. Water samples were collected once a month during the period from May to November in 2014. In water samples the concentration of dissolved oxygen, Cl-, SO42-, N-NH4+, P-PO43- and the values of pH, BOD5 and electrolytic conductivity were indicated. Based on the obtained results, loads of the individual components in river waters were calculated as a product of concentration and Supraśl waters flow rate in a particular month. Supraśl waters, due to values of most analyzed parameters, should be classified as first quality class. The source of Cl-, SO42-, N-NH4+ in Supraśl waters were treated wastewater and other anthropogenic sources associated with the basin development. Reduced Supraśl water quality is caused by the inflow of organic substances expressed by BZT5 from natural and anthropogenic origin and concentration of PO43-, which were mainly delivered with treated wastewater.

In this paper, the degree of contamination of water was determined from anthropogenic reservoirs, located in the area of former coal mine Rozbark in Bytom. The physicochemical analysis of water indicated a high degree of anthropopression. In all analyzed reservoirs, permissible concentrations of chlorides and sulphates were exceeded. In the majority of them, the values of electrical conductivity and total suspended solids were also exceeded. In order to determine the transformation of surface water contamination, there was a comparison of archival data of water quality and laboratory tests performed after five years. Comparative analysis shows that in the last five years, there has been no improvement in the quality of the analyzed surface waters. In fact deterioration of the quality was noticeable.
