Opis:
The present study aimed to assess groundwater quality according to the water quality index (WQI) in Ali Al- Gharbi district of the Maysan Governorate in eastern Iraq. For this purpose, 10 physical parameters such as pH, total hardness (TH), magnesium (Mg2+), calcium (Ca2+), potassium (K+), sodium (Na+), sulphate (SO42–), chloride (Cl–), nitrate (NO3–), and total dissolved solids (TDSs) were examined since 2019 from 16 different locations (viz. wells). The analysis results indicated that 18.75% of the water samples were of good quality, 56.25% of them had low quality, and 25% of such samples were very poor. The WQI also varied from 69.67 and 297.6. Therefore, prior to water use, there is a dire need for some treatments, as protecting this district from pollution is significant.

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:
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.

Water Quality index indicating the water quality in terms of index number, offers a useful representation of overall quality of water for public or for any intended use, as well as in pollution abatement programmes and in water quality management. The present study was carried out to determine the Water Quality Index (WQI) of selected rivers in Warri, Delta State, using fourteen physicochemical parameters and on the basis of weighted Arithmetic Index in order to access the suitability of this water for consumption, recreation and other purposes. The parameters were measured monthly for one year at the six selected water bodies. In this study, WQI was determined by the analysis-on the basis of various physicochemical parameters such as pH, chlorides, electrical conductivity, dissolved oxygen, biochemical oxygen demand, total dissolved solid, total suspended solids, chlorides, sulphates, chemical oxygen demand, oil/grease. Result obtained for the different sampling sites were found to fall within the WQI classifications - poor water (100-200) to unsuitable water or unfit (>300). There is, therefore, the need to periodically assess these water bodies to ensure the quality is suitable for the intended purpose.

Opis:
Rivers are considered the most important sources of surface water on Earth. They are play a significant role in all human activities and the quality of river water is needed. Therefore, the importance of the water quality index is arising through providing data base about quality of the water source, and explain the change in the water quality over a period of time continually. This study involved determination of physicochemical and biological parameters of Lower Zab river in Kirkuk city at two different points. The objectives of the study are to assess the present water quality, through analysis of some selected water quality parameters like pH, TDS, BOD, dissolved oxygen, turbidity, EC, alkalinity, and salinity etc. and to compare the results with the Canadian Council of Ministers of the Environment and National Sanitation Foundation Water Quality Indices. Raw water samples were collected from the Lower Zab river twice a month by one sample every 15 days from each station. The water quality data include 16 different parameters. Tests were carried out following the American Public Health Association standard methods. The results show that all parameters values were within the standards of drinking water proposed by the CCME standards and Iraqi standards or the World Health Organization standards for drinking purpose, except turbidity, DO, nitrate, calcium, which were mostly higher than the standards and sometimes BOD and potassium. The results of WQI showed that the water quality at LZ3 station is lower than LZ2 station due to the polluting activity of the Lower Zab river. Furthermore, for the years 2014, 2015, and 2016, the water quality was degraded due to the ISIS war. Also, it was noted in the 2013 year that the water quality degraded more in fall and winter seasons due to that the earth has exposed to the long-dried season and then suddenly exposed to a high rainfall season which in turns leads to increase some parameters very high (i.e. turbidity). Finally, the Lower Zab river water cannot be use for drinking directly. However, a pretreatment is needed before the drinking use.

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.

Twenty groundwater samples were collected and then examined for physical (pH, EC, TDS) and chemical (Na+, K+, Ca2+, Mg2+, HCO3−, Cl−, SO42−, NO3) parameters, followed by multivariate statistics to determine the current state of groundwater quality and to assess the suitability of these resources for drinking and irrigation purposes in the Baser Sakhra area localized in Eastern of Algeria. The analysis carried out showed that the cations trend in most of the groundwater samples is on the order of Ca2+˃Na+˃Mg2+˃K+ and the anions trend is on the order of HCO3-˃SO42-˃Cl-. Stabler diagram demonstrated the predominance of Ca2+- HCO3- hydro-chemical facies (80%). Moreover, the parameters, such as sodium adsorption ratio, percentage sodium, residual sodium carbonate, permeability index, Kelly’s ratio, potential salinity, and magnesium hazard were evaluated for the suitability of groundwater for irrigation. The values obtained in this investigation concluded that most of the groundwater samples are suitable for irrigation. From the other approach, the Water Quality Index (WQI) for drinking was also used in the current study. WQI ranged from 72.46 to 506.426, indicating that 40% of the samples were suitable for drinking however, 60% of them belong to the poor to unsuitable category of drinking water in terms of physicochemical properties, according to the World Health Organization norms.

Opis:
The use of treated wastewater for irrigation purposes will be an essential component for sustainable water resources management, especially in the water-stressed countries as in Jordan. In this context, an attempt has been made to determine the suitability of effluent quality of selected wastewater treatment plants in Jordan for the irrigation purposes based on weighted arithmetic water quality index (WQI) approach, according to the Jordanian standards for reclaimed domestic wastewater. The effluent wastewater quality records from 22 wastewater treatment plants within a one-year-monitoring period from March 2015 to February 2016 were used. Fifteen physical, chemical, and microbiological parameters were selected to calculate WQI. According to the WQI scale classification, most of the selected wastewater treatment plants were not in full compliance with the Jordanian standards for the reclaimed domestic wastewater regarding the direct reuse of treated wastewater for the irrigation purposes. Therefore, for category A (i.e., vegetables that are normally eaten cooked, parking areas, sides of roads inside cities, and playgrounds), one plant is classified in the 'Excellent water' class and six plants as a "Good water" class. For category B (i.e., irrigation of fruit trees, green areas, and sides of roads outside the cities), one plant is classified in the 'Excellent water' class and twelve plants as a "Good water" class. For category C (i.e., irrigation of industrial crops, field crops, and forest trees), one plant is classified in the 'Excellent water' class and fifteen plants as a "Good water" class. The effective weight calculations identified that E. coli is considered the most effective parameter in the WQI values in category A, and to a lesser extent, SAR, pH, BOD, and NO3. For category B, the SAR, pH and E. coli parameters are considered the most effective parameters in the WQI values. In turn, for category C, the SAR, pH, and PO4–3 parameters are considered the most effective parameters in the WQI values. Thus, these parameters based on category are considered as the main parameters which degrade the effluent wastewater quality for irrigation purposes. The results of this study are beneficial for the water managers and policymakers for proper actions on water resources and agricultural management in Jordan.

Opis:
Groundwater is a key source of drinking water in Jordan. This study was conducted to assess the suitability of groundwater in major groundwater basins in Jordan for drinking purposes. The groundwater quality data from sixteen sampling stations within one-year-monitoring period from March 2015 to February 2016 were used. Weighted arithmetic water quality index (WQI) with respect to the Jordanian standards for drinking water was used for quality assessment. Sixteen Physical, chemical and microbiological parameters were selected to calculate WQI. The result showed that all physical and chemical parameters were almost below the maximum allowable level based on the Jordanian standards for drinking. On the other hand, the microbiological parameter (i.e. E.coli count) was exceeded the maximum allowable limit in all the studied locations based on the Jordanian standards for drinking water. The computed WQI values range from 40 to 4295. Therefore, out of 16 studied locations, three locations are classified in the “Excellent water” class, nine locations as a “Good water” class, one as a “Poor water” class, two as a “very poor water” class, and one as a “water unsuitable for drinking purpose” class. Furthermore, Escherichia coli is considered the most effective parameter on the determination of WQI in this study. This result highlighted the importance of including the microbiological parameters in any drinking water assessment, since they reflect with other physical and chemical parameters the actual condition of water quality for different purposes.

Data gathering and implementation took place throughout winter and summer. Water samples were taken periodically, according to the standard method, the research was carried out by collecting different random samples for eight months (Jun. 2015–Jan. 2016) and measuring (turbidity, total hardness, pH, total dissolved solids, suspended solids, Cl–, Mg2+, Fe2+,NO3–, NH3+) for each sample. Five different approaches and methodologies of calculating the water index were applied. The results revealed that the Water Quality Indices varied from 70.55 to 88.24, when applying Canadian Council of Ministers of the Environment Water Quality Index (CCMEWQI) and British Columbia water quality index (BCWQI) geometric weighted mean respectively. All the results, from the five approaches indicated good water quality, multiple regression analyses were conducted for turbidity, total hardness and suspended solids, they found that these parameters are strongly related to each other and to other parameters.

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.

The study aimed to assess the surface water quality in the Hau Giang province in 2021 at 44 locations (with a frequency of 5 times per year) using Principal Component Analysis (PCA), Cluster Analysis (CA) and GIS. Surface water quality was compared with the national technical regulation on surface water quality (QCVN 08-MT:2015/BTNMT, column A1) and Water Quality Index (WQI). The results showed that the surface water quality parameters of total suspended solids, organic matters, nutrients, coliform, and Fe far exceeded the allowable limits, while the Cl-, color, and CN- parameters were within the allowable limits of QCVN 08-MT:2015/BTNMT, column A1. The values of WQI showed that the water quality of the Hau Giang province ranged from poor to excellent. The water quality at the Vam Cai Dau and Hau River areas could only be exploited for water supply, but appropriate treatment is needed. CA divided the monitoring months into three distinct clusters and reduced the sampling sites from 44 to 33 locations, reducing 25% of monitoring cost per year. PCA revealed three main factors which could explain 69.0% of the variation in water quality. The water pollution sources were mainly industrial and agricultural discharges, domestic and urban activities, transportation activities, salinity, hydrological conditions and water runoff. The current findings provide useful information which support local environmental managers and water supply companies for safe and sustainable.

Opis:
The current study was undertaken to assess the physicochemical quality of the Kufranja dam (KD) surface water in northern Jordan during the summer and winter seasons [2019]. The samples were analyzed for temperature, pH, dissolved oxygen, conductivity, major cations, major anions, and heavy metals. Most of the physicochemical parameters exhibited a similar spatial distribution, where the maximum concentrations were observed at the dam’s entrance, while the minimum concentrations were recorded at the dam’s end. This indicates that the factors affecting their occurrence and distribution are the same, including natural discharges from the surrounding catchment areas, weathering products, agricultural activities, and wastewater effluents that enter the dam via Wadi Kufranja. All the physicochemical parameters and heavy metals in KD water lie below the maximum permissible levels of the Jordanian and international standards for drinking and irrigation, except for EC values that are above WHO standards for drinking. The application of the water quality index (WQI) depicts that the KD water is chemically unsuitable for use in drinking and needs proper treatment before use. The irrigation indices (SAR, Na%, and MH) indicate that the KD water is chemically suitable for irrigation, whereas EC results and USSL diagram showed that the dam’s water is suitable for irrigation and belongs to the categories of good to permissible for irrigation. Therefore, KD water is suitable for irrigation of most soils (except soils with low salt tolerance). Crops with good salt tolerance are recommended and a special treatment of salinity might be required.

Developments in agriculture, industry, and urban life have caused the deterioration of water resources, such as rivers and reservoirs in terms of their quality and quantity. This includes the Saguling Reservoir located in the Citarum Basin, Indonesia. A review of previous studies reveals that the water quality index (WQI) is efficient for the identification of pollution sources, as well as for the understanding of temporal and spatial variations in reservoir water quality. The NSFWQI (The National Sanitation Foundation water quality index) is one of WQI calculation methods. The NSFWQI is commonly used as an indicator of surface water quality. It is based on nitrate, phosphate, turbidity, temperature, faecal coliform, pH, DO, TDS, and BOD. The average NSFWQI has been 48.42 during a dry year, 43.97 during a normal year, and 45.82 during a wet year. The WQI helped to classify water quality in the Saguling Reservoir as “bad”. This study reveals that the strongest and most significant correlation between the parameter concentration and the WQI is the turbidity concentration, for which the coefficient correlation is 0.821 in a dry year, and faecal coli, for which the coefficient correlation is 0.729 in a dry year. Both parameters can be used to calculate the WQI. The research also included a nitrate concentration distribution analysis around the Saguling Reservoir using the Inverse Distance Weighted method.

Opis:
In the study suitability of water quality index approach and environmetric methods in fi ngerprinting heavy metal pollution as well as comparison of spatial variability of multiple contaminants in surface water were assessed in the case of The Gediz River Basin, Turkey. Water quality variables were categorized into two classes using factor and cluster analysis. Furthermore, soil contamination index was adapted to water pollution index and used to fi nd out the relative relationship between the reference standards and the current situation of heavy metal contamination in water. Results revealed that surface water heavy metal content was mainly governed by metal processing, textile and tannery industries in the region. On the other hand, metal processing industry discharges mainly degraded quality of water in Kemalpasa and Menemen. Furthermore, Kemalpasa region has been heavily affected from tannery and textile industries effl uents. Moreover, pollution parameters have not been infl uenced by changes in physical factors (discharge and temperature). This study indicated the effectiveness of water quality index approach and statistical tools in fi ngerprinting of pollution and comparative assessment of water quality. Both methods can assist decision makers to determine priorities in management practices.

Opis:
In Indonesia, the river water quality has been determined based on Government Regulation of the Republic of Indonesia No. 22 of 2021. This study aimed to determine the quality of surface water from the Damsari, Jabawi, Kleblow, and Komba Rivers in Jayapura Regency based on the monitoring data from 2016 to 2019. The CCME-WQI method is used to determine the status of rivers based on river water quality standards (class 1 to class 4). The results of the study showed that the parameters of water temperature, TDS, pH, $NH_3, NO_3^-, SO_4^-2$, surfactant, oil/grease, Cr-(IV), Mn, Fe, Fecal Coliform, and Total Coliform were still in accordance with the quality standard. Meanwhile, TSS, COD, BOD, Total Phosphate, Hg, and Ni have exceeded the water quality standard, where the dominant pollutant source is an anthropogenic waste. On the basis of the WQI average value, the four rivers are not suitable as a source of drinking water (Poor-Marginal; 41.33 – 58.25). The Jabawi River can be used as a recreational facility, but it must be under special management (Fair; 69.75), while the other three rivers are not suitable (Marginal; 52.00 – 61.67). The Jabawi and Komba Rivers are in the Fair category (75.50 and 69.33) to support aquatic life, while the Damsari and Kleblow Rivers are in the Marginal category (59.00 and 61.25). The water quality of the four rivers is very good and suitable to be used as a water source for irrigation (Good category; 80.00 – 88.00). The strategies for controlling river water pollution and increasing the role of the government, stakeholders, and the community are needed.

Opis:
Aluminium slag waste is a residue from aluminium recycling activities, classified as hazardous waste so its disposal into the environment without processing can cause environmental problems, including groundwater pollution. There are 90 illegal dumping areas for aluminium slag waste spread in the Sumobito District, Jombang Regency. This study aims to evaluate the quality of shallow groundwater surrounding aluminium slag disposal in the Sumobito District for drinking water. The methods applied an integrated water quality index (WQI) and heavy metal pollution index (HPI), multivariate analysis (principal component analysis (PCA) and hierarchical clustering analysis (HCA)), and geospatial analysis for assessing groundwater quality. The field campaign conducted 40 groundwater samples of the dug wells for measuring the groundwater level and 30 of them were analysed for the chemical contents. The results showed that some locations exceeded the quality standards for total dissolved solids (TDS), electrical conductivity (EC), and Al2+ . The WQI shows that 7% of dug well samples are in poor drinking water condition, 73% are in good condition, and 20% are in excellent condition. The level of heavy metal contamination based on HPI is below the standard limit, but 13.3% of the water samples are classified as high contamination. The multivariate analysis shows that anthropogenic factors and natural sources/geogenic factors contributed to shallow groundwater quality in the study area. The geospatial map shows that the distribution of poor groundwater quality is in the northern area, following the direction of groundwater flow, and is a downstream area of aluminium slag waste contaminants.

Opis:
This research focuses on the ground water quality index in Ado-Ekiti State, Nigeria. Groundwater sample wells were randomly collected and their spatial locations captured using a handheld GPS. Water samples were taken from 45 wells and their physio-chemical properties were analyzed in the laboratory. Spatial distribution maps of the water quality parameters were then developed. Herein, the Kriging method of interpolation from geospatial analyst wizard in Esri ArcGIS software was deployed in the generation of thematic maps of water quality parameters. A drinking water quality index was subsequently developed to describe the overall quality of groundwater in the study area. Laboratory analysis of 34 wells showed water of acceptable use as it conforms to WHO standard, while 11 wells were found to have unsuitable water for domestic use. The results further show spatial variation in the water quality. The south central depicts poor water quality, fair water quality in the south-east, while the North, north east, north-west down to the south west depicted the best water quality.

Opis:
The Shatt al-Arab river is the main water source in the Basrah province, subjected to significant environmental and hydrological changes that have led to the complete degradation of its ecosystem, particularly the middle section. Nineteen water quality variables were selected to assess spatio-temporal changes in the middle section. Eight variables were chosen with the most significant impact on the Shatt al-Arab River water quality in calculating the water quality index (WQI). These variables were measured every month from December 2020 to November 2021 at five observation stations (Abu-Flous, Mhela, Baradeyea and Maqal) located on the main river and one on the Karmat Ali canal, which connects the Shatt al-Arab River with east Hammar marsh. The study was divided into two seasons of the year, the wet season (December 2020 – May 2021) and the dry season (July 2021 – November 2021), in the calculation of the WQI and its annual calculation. The results of the current study show deterioration in the values of most water quality variables, particularly those related to dissolved salts and organic and bacterial pollution. Water quality was also classified as poor on the WQI scale at all stations for the duration of the study. The results of the WQI indicated the deterioration in the quality of the water middle section, particularly during dry season. The degradation of the waters of the middle section of the Shatt al-Arab River is due to two main factors: increase salinity and organic pollution. In general, the Shatt al-Arab River and the middle section in particular, need comprehensive management, including a clear and expeditious plan to identify and address the degradation of the river’s environment, which has a great importance to all residents of the Basrah province.

The water quality index (WQI) is an essential indicator to manage water usage properly. This study aimed at applying a machine learning-based approach integrating attribute-realization (AR) and support vector machine (SVM) algorithm to classify the Chao Phraya River’s water quality. The historical monitoring dataset during 2008-2019 including biological oxygen demand (BOD), conductivity (Cond), dissolved oxygen (DO), faecal coliform bacteria (FCB), total coliform bacteria (TCB), ammonia (NH3-N), nitrate (NO3-N), salinity (Sal), suspended solids (SS), total nitrogen (TN), total dissolved solids (TDS), and turbidity (Turb), were processed via four studied steps: data pre-processing by means substituting method, contributing parameter evaluation by recognition pattern study, examination of the mathematic functions for quality classification, and validation of obtained approach. The results showed that NH3-N, TCB, FCB, BOD, DO, and Sal were the main attributes contributing orderly to water quality classification with confidence values of 0.80, 0.79, 0.78, 0.76, 0.69, and 0.64, respectively. Linear regression was the most suitable function to river water data classification than Sigmoid, Radial basis and Polynomial. The different number of attributes and mathematic functions promoted the different classification performance and accuracy. The validation confirmed that AR-SVM was a potent approach application to classify river water’s quality with 0.86-0.95 accuracy when applied three to six attributes.

Opis:
Water quality index (WQI) is a mathematical tool used to transform large quantities of water quality data into a single number which present water quality level. The aim of the present study is to evaluate the quality of Koudiat Medouar Dam in Batna (Algeria) to assess its suitability for drinking purposes. Samples were assessed for ten (10) physicochemical settings namely pH, electrical conductivity, total hardness, nitrate, sulphate, chloride, calcium, magnesium, dissolved oxygen and turbidity. The calculation of WQI was done via weighted arithmetic index method. The WQI values ranged from 99.097 to 174.92 during 2015. It reflected that the water samples were in February in the range of very poor quality and ranged to be in unsuitable for drinking rang in the all other months. The WQI of the present study reveals dam water is contaminated and not suitable for drinking purpose without giving treatment.
Indeks jakości wody (WQI) jest matematycznym narzędziem używanym do transformacji dużej liczby danych o jakości wody w jedną liczbę, która charakteryzuje poziom jakości wody. Celem przedstawionych badań było określenie jakości wody w zbiorniku zaporowym Koudiat Medouar w Batna (Algieria), aby ustalić jej przydatność do celów spożywczych. W próbkach oceniano 10 parametrów fizycznych i chemicznych: pH, przewodność elektrolityczną, całkowitą twardość, stężenie azotanów, siarczanów, chlorków, wapnia, magnezu, rozpuszczonego tlenu i mętność. Obliczenia indeksu WQI wykonano metodą ważonego indeksu arytmetycznego. Wartości WQI zmieniały się od 99,097 do 174,92 w 2015 r. W lutym próbki wody cechowała bardzo zła jakość, a w pozostałych miesiącach woda nie nadawała się do picia. Indeks ustalony w niniejszych badaniach dowodzi, że woda w zbiorniku zaporowym jest zanieczyszczona i nie nadaje się do celów spożywczych bez uprzedniego uzdatniania.

Opis:
Surface water is subject to strong anthropogenic pressures caused by the development and the extension of the agricultural activities and also by the industrial and domestic activities. Pollution is a major environmental problem due to discharges into rivers and the excessive use of agricultural fertilizers add to that the discharges from urban and industrial sources. The aim of this study is to assess the quality and the state of the organic pollution of surface water in the Kébir wadi east, based on the Water Quality Index (WQI) and the Organic Pollution Index (OPI) during six sampling campaigns carried out between April and September of the year 2011. Seven stations were studied along the Kébir wadi east downstream from the Mexa Dam. The results are visualized by the use of GIS through making thematic maps. They revealed that half of the stations show excellent to good water quality and moderated organic pollution except the stations S3, S6 and S4, that have poor water quality and high pollution at S3 and S6 respectively, and non-potable water with very high organic pollution at S4. The anthropogenic environmental deterioration recorded in the wadi is the result of the use of nitrogen and phosphate agricultural fertilizers and especially, the discharge of untreated domestic and industrial wastewater from neighbouring agglomerations. The seasonal variation remains discrete and reflects a slight tendency to the deterioration of the waters of El Tarf region during the low waters of the summer period.

Opis:
Morze Azowskie jest najmniejszym i najpłytszym morzem na świecie o małym zasoleniu. Takie właściwości powodują jego podatność na degradację pod wpływem działalności antropogenicznej. Jednym z głównych źródeł zanieczyszczeń Morza Azowskiego jest huta „Azovstal” w Mariupolu (Ukraina). Negatywny wpływ huty jest związany przede wszystkim z dużą ilością odprowadzanych do morza ścieków chłodniczych i technologicznych. W pracy przedstawiono wyniki oceny oddziaływania ścieków z huty na jakość wody morskiej i sytuację ekologiczną w strefie ich odprowadzania, dokonanej na podstawie metod stosowanych w Ukrainie oraz obowiązujących standardów jakości wód powierzchniowych. Kompleksową ocenę dokonano na podstawie wartości trzech wskaźników jakości wody morskiej – wskaźnika jakości wody (WJW), wskaźnika zanieczyszczenia wody (WZW) oraz zintegrowanego wskaźnika stanu ekologicznego (ZWSE), a także z uwzględnieniem tak zwanej zasady sumowania. Na podstawie wyników przeprowadzonej oceny wykazano, że odprowadzanie ścieków z huty „Azovstal” prowadzi do znacznego wzrostu stopnia zanieczyszczenia wód w strefie przybrzeżnej Morza Azowskiego, co stanowi zagrożenie ekosystemu morskiego i ogranicza wszystkie rodzaje użytkowania wody.
The Sea of Azov is the smallest and shallowest sea in the world with low salinity. Such properties determine its susceptibility to degradation due to anthropogenic activities. The Azovstal Iron & Steel Works in Mariupol (Ukraine) is one of the main sources of pollution of the Azov Sea. Adverse impact of the steelworks is associated primarily with the large amount of technological and cooling wastewater discharged into the sea. The paper presents the impact assessment results of wastewater discharge on the sea water quality and the ecological conditions in the discharge zone. The assessment was performed using local Ukrainian methodologies as well as applicable surface water quality standards. The comprehensive assessment was based on the three numerical integrated indicators of sea water quality: the Water Quality Index (WJW), the Water Pollution Index (WZW), the Integrated Ecological State Index (ZWSE), and the so called principle of aggregation. Based on the assessment results it was demonstrated that the wastewater discharge from the Azovstal Iron & Steel Works leads to significant increase in water pollution in the coastal zone which brings threat to the marine ecosystem and limits all types of water consumption.

Water is very plentiful through the planet in general. Nevertheless, clean drinking water is not always accessible in the proper time or place for sufficient public or ecological use. The water significance is emphasized by the fact that in the past, great cultures have arisen near and along water bodies. Water quality of some purification complexes (compact units) in the Babylon Province (13 compact unit) as compared with Al-Hillah Al Mouahad Project (water treatment plant) was assessed by the Water Quality Index (WQI) methodology. WQI offers a particular number that states the overall water quality at a definite place and period based on many parameters concerning the quality of water. The water produced from the compact units was classified as "good water" according to the WQI classification with the values ranging from 85.4 in Bermana unit to 99.17 in Al-Muamera compact unit. Moreover, the research results showed that the water purification complexes work with efficiency, very close to the performance of large water purification projects and stations, and this means that it is possible to rely on them to obtain good drinking water quality, especially in small or remote areas.

The results of a research into the scale and consequences of the degradation of aquatic ecosystems in Ukrainian Polesie have been detected in article, and the areas of increased anthropogenic pressure have been identified which greatly affect the condition and number of aquatic macrophytes. The biodiversity of sites with different anthropogenic load was evaluated using the biodiversity criteria. In the research, the structural and functional features of macrophytic species diversity within Teteriv River ecological corridor as a typical river landscape of Ukrainian Polesie were determined and described, the floristic composition was determined. Within the ecological zones, the number of species and their projective coverage in areas with different anthropogenic pressures within Teteriv River ecological corridor were determined. The basic criteria for the implementation of deferred biomonitoring based on the analysis of the dynamics of the species composition of the phytocoenoses of Teteriv River ecological corridor on the indicators of ecological stability and plasticity using the species-specific criteria, are: Margalef species richness index, Sørensen–Dice index, Shannon diversity index, Simpson’s index, and Pielou’s evenness index. Based on the results, correlation dependencies have been constructed, which will allow to obtain data on the stability of the development of aquatic ecosystems according to the data of species surveys. Interconnections between biodiversity indicators and indicators of surface water quality within the Ukrainian Polesie were found; they are the fundamental component of a long-term monitoring of the stability in the development of aquatic phytocenoses.

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 use of phytoplankton as an indicator of water pollution is a promising tool for assessment of water quality. The purpose of this study was to determine whether diversity indices, including the species richness and diversity of phyto-plankton, could be used for reliable assessment of water quality in the Wadaslintang Reservoir in Indonesia. Surveys were conducted monthly at eight sites, from July 2019 to October 2019. Phytoplankton was collected during the day at 10:00 until approximately 15:00 in the euphotic zone. The parameters investigated were species richness and the abundance of phytoplankton, as well as water quality parameters listed in Government Regulation Number 82 of 2001. The level of pollution was represented biologically by the Shannon–Wiener diversity index and physicochemically by the STORET (storage and retrieval of water quality data) index. Moreover, the two indices were compared to determine whether a particular diversity index was more effective for assessment of this reservoir. The results showed that during the dry season, 22 taxa of phytoplankton were present, belonging to Cyanophyta, Chlorophyta, Chrysophyta, and Euglenophyta. During the wet season, 29 taxa were found, belonging to Cyanophyta, Chlorophyta, and Chrysophyta. Based on the Shannon-Wiener index and STORET index, water quality was better during the wet season than during the dry season. The results of water quality assessment using both indices were consistent, but the diversity index was a more sensitive indicator of pollution levels. Therefore, the Shannon–Wiener index is a useful tool for assessment of water quality in the Wadaslintang Reservoir.

Opis:
A good water quality is essential to sustaining the life of the organisms. The determination of water quality is needed as a direction to monitoring the water pollution. The purpose of this study is to examine the quality of the water and to determine the water pollution index based on the physicochemical parameters in Mimika waters, Indonesia. The sampling of water quality was carried out in October 2016 at six stations (Moga, Puriri, Inaoga, Keakwa, Atuka and Pomako waters). Then, the results were compared with the standard of sea water quality for biota marine based on the Decree of the Minister of Environment No. 51 year 2004. This study showed that the physicochemical parameters of the waters, such as water turbidity, BOD, NH3 and heavy metals (Hg, As, Cd, Pb, Cu, Zn, Ni and Cr), are still appropriate to the biota marine in all study stations. However, there is a parameter for which the quality standards were exceed in all locations, including water salinity for coral and seagrass, NO3, PO4 and H2S. The result of pollution index calculation at coastal waters Mimika are classified as lightly polluted (Keakwa and Pomako waters), and moderately polluted (Moga, Puriri, Inaoga and Atuka waters) with the pollution index values of 3.51 to 6.95. It is important to notice that the parameters of quality standards which had been exceed such as NO3, PO4 and H2S are the environmental parameter for nutrient elements and can trigger eutrophication in the waters.

Opis:
The leachate coming from the landfill is a serious problem. This is because the leachate water can contaminate the wells of the residents around the landfill. This research was conducted at Jabon Landfill located in Jabon District of Sidoarjo Regency, East Java Province, Indonesia. Jabon Landfill has been operating since 2003 with a controlled landfill system that has triggered environmental risks due to the leachate output. The purpose of this study was to determine the classification of the shallow groundwater quality status based on the pollution index (PI) around Jabon Landfill at a distance of around 250 meters, 500 meters and 1,000 meters from the landfill. The pollution index was determined by analyzing the pollutant concentration consisting of these following parameters: pH, BOD, COD and Fe. The results of the analysis show that the pH parameter had a higher value than the pH at Jabon Landfill of 7.2–7.5. The pH at Jabon Landfill was 6.35. The Fe parameter shows that the value of 1.694 in the groundwater well closest to Jabon Landfill and the wells further away indicates that the Fe concentration was lower for the latter, namely 0.081 at a distance of up to 200 meters. On the basis of the Pollution Index, the highest value was 5.45 at Well 7 is located 196 m from Jabon Landfill. Meanwhile, the well furthest from Jabon Landfill at a distance of 1,000 m showed a lightly polluted status with a Pollution Index of 1.91. The further the location of the well away from Jabon Landfill, the Pollution Index value tended to decrease. This means that the pollution status generally improves. Overall, the pollution status of the 18 wells shows that 2 wells are moderately polluted, 15 wells are lightly polluted and 1 well is in good condition.

Water pollution in rivers is still a crucial problem for the countries that use river water as the primary water source. This study aimed to determine the water quality of the Musi river and the content of heavy metals in water, sediment and mussels as well as to predict the water quality of the Musi river in the next five years. The water samples were taken from 18 stations (sampling points) from upstream to downstream to be checked physically, chemically and biologically. Prediction of the river water quality was made using the QUAL2Kw software. The research results show that the Musi River water is categorized as lightly polluted with concentrations of TSS and DO that have passed the threshold. The heavy metals in river water, such as Pb and Cr have also passed the quality standard. The Fe, Mn, and Zn concentrations are pretty high in the sediment. In turn, in mussels, the metals measured were Fe, Cu, and Zn. The prediction results reveal that several values of the river quality parameters will pass the threshold value with the same pattern tendency from each station.

Opis:
Batujai reservoir is located in Central Lombok Regency, Indonesia. The government and local people use it for hydropower generation, drinking water, agricultural irrigation, fish farming, and tourism. The phenomenon of growing population and increasing industrial activities in the catchment area of Batujai reservoir always result in the discharge of various pollutants into the aquatic environment and cause the blooming of water hyacinth over almost 30% of the reservoir area. The aim of this study was to determine the water pollution index of Batujai reservoir. The samples were analysed for the following parameters: pH, temperature, DO, COD, BOD, TSS, and heavy metals. The research was done by using purposive sampling method and determination of water quality status with STORET method based on Government Regulation No. 82/2001. The measurement results show that the physical and chemical parameters of the Batujai reservoir water do not exceed the quality standard are the temperature (29 to 32°C); pH (6.6 to 7.5 mg/L); nitrate (0.421 to 0.546 mg/L); Cd (0.0005 to 0.005 mg/L); Cr (<0.001 to 0.018 mg/L); and the parameters that exceed quality standards are DO (3.8 to 4.9 mg/L); BOD (3.03 to 4.21 mg/L); COD (6.8 to 10.1 mg/L); phosphate (0.181 to 0.237 mg/L); and Pb (0.14 to 0.24 mg/L). The water quality status of Batujai reservoir was heavily polluted for standard quality on class I, II, III and moderately polluted for class IV.

The paper presents change of water quality within Vistula River in the city of Warsaw. Water samples for analysis were taken from four different measurement points in the period from February to June 2016. Based on the results of laboratory studies it was demonstrated that the Vistula River in Warsaw is exposed to the input of pollutants contributing to increase the salinity, especially in winter and early spring. The concentration of both chlorides and sulphates were highest in February and was decreasing in subsequent months of the year. At the same time it has been shown that during the entire study period the concentration of Cl– ion exceeded the limit values for water quality II class in Poland. While the SO4 2– concentrations in water samples taken in the winter months (February-March) exceeded the limit values for the second quality class, in April, it was within the acceptable range for II class water quality, and in May and June does not exceed the value referred to as standard for I class of water quality. Based on the analysis of indicators of nutrients (N-NH4 , N-NO3 , Ptot.) it was found that the Vistula is not exposed to eutrophication due to their low concentration, which indicates a very good water quality. At the same time permanganate index (CODMn) indicates a low organic load of Vistula.

Warna and Pengilon Lakes are very close to each other and connected with the sill, a famous tourist destination in the Dieng Plateau Java. Land-use changes are the main problem that affected the lakes. The conversion of forest into an agricultural area had induced erosion and increased the volume of nutrients discharged to the lake due to high use of fertilisers in potatoes farms. In the dry seasons, water from those lakes was pumped to irrigate agricultural land. This study aimed to determine the water quality of Warna and Pengilon Lakes based on physical, chemical parameters, and phytoplankton communities. Water samples were collected from 4 sites at each lake to analyse biological oxygen demand (BOD), chemical oxygen demand (COD), ammonia, nitrate, nitrite, and total nitrogen (TN). Temperature, pH, dissolved oxygen (DO), turbidity, and conductivity (EC) were measured in-situ. During this research, turbidity and BOD in Warna and Pengilon Lakes exceeded the Indonesian water quality standard. Based on the STORET method, the water quality of Lake Warna was assessed as highly polluted for all classes. However, based on the pollution index (PI), Lake Warna was slightly to moderately polluted, as well as the saprobic index was in the β-mesosaprobic phase. Based on the species diversity index of phytoplankton, both Warna and Pengilon Lakes were moderately polluted. The long-term monitoring studies are necessary as an early warning sign of water quality degradation. Therefore, they provide insight into the overall ecological condition of the lake and can be used as a basis for developing suitable lake management.

Opis:
Assessment of temporal variation of the water quality is an essential aspect of evaluating temporary changes in a water body caused by natural or artificial contributions. The study aims to assess the water quality temporal variation and the water quality index over the year from 2010 to 2019. Water sampling was carried out near the bridge of the Kotte canal. Water quality parameters such as pH, electrical conductivity (EC), temperature, dissolved oxygen (DO), ammonia, nitrate, phosphate, and chemical oxygen demand (COD) were determined to assess the quality of water at different periods. It has been calculated based on the standard of the central environmental authority of Sri Lanka. The weighted arithmetic index method has been used to calculate the water quality index. The water quality index of the study area was recorded as good (33.60760) in 2010 and poor in 2013 (56.95663), 2016 (52.37269), and 2019 (69.04417). The study revealed that the water temperature in the canal fluctuates with the time and climate of the area. The EC of the water is registered within the reference range. However, pH, COD, DO, and ammonia are the main water parameters deviating from the reference range. It is observed that the leading causes of the deterioration of water quality are human activities, the illegal discharge of sewage and industrial wastewater, the lack of adequate sanitation facilities, and urban runoff.

Opis:
The eventual polluting of the Ouichane region’s groundwater by heavy metals around an abandoned iron mine was investigated. To reach this aim, the research began with a questionnaire survey to assess local people’s use of and appreciation for well and spring water, followed by measurement of spatial pollution load of heavy metals: Al, Ag, Fe, Cd, As, Cr, Co, Zn, Pb and Cu for water samples collected from twelve wells and three spring drinks of water using inductively coupled plasma-atomic emission spectrometry method (ICP). Determining the overall quality of spring and well water for human use was also performed by calculating the heavy metal pollution index (HPI). As result, the survey revealed that 44.90% of the households are not connected to the drinking water network, 97.3% of them use well water, which is highly appreciated, and 88.1% of the population consider its quality to be good to excellent. Meanwhile, the ICP analysis showed that all the water samples contain heavy metals. In fact, the maximum concentrations (expressed in 10-5 g/l) recorded per element were 9.7 for (Ag), 15 for (Al), 6.9 for (As), 4.5 for (Cd), 5.6 for (Co), 31 for (Cr), 14 for (Cu), 858 for (Fe), 7 for (Pb) and 2.9*10-5 g/l for (Zn). Moreover, most of the water samples recorded heavy metal values above World Health Organization (WHO) limits, for at least one metal among the ten tested, with high concentrations of iron observed in all samples. The HPI values for the three explored sources (S1, S2 and S3) and for 8 out of 12 wells (P3, P4, P5, P6, P7, P8, P9 and P10) exceed the critical pollution value and identify non-potable water with a high potential of contamination. Consequently, the results of this study raise the question about groundwater around this abandoned mining area, especially in the long term, the use of groundwater could increase because of the succession of years of drought on Moroccan territory and hence may constitute a significant health risk for most of the inhabitants.

Obecny poziom technik komputerowych pozwala na ich skuteczne wykorzystanie w procesie monitorowania działania systemów wodociągowych oraz do analizy ich krytycznych elementów, w aspekcie jakości dostarczanej wody. W pracy przedstawiono analizę niezawodnościową funkcjonowania monitoringu jakości wody, na przykładzie systemu zaopatrzenia Wrocławia w wodę. Przeprowadzona analiza obejmowała wyznaczenie intensywności występowania jakości wody niezgodnej ze standardami, średniego czasu trwania nieodpowiedniej i odpowiedniej jakości wody w sieci wodociągowej, prawdopodobieństwa dostarczenia wody o wymaganej jakości, a także wartości wskaźników gotowości i niezawodności dostawy wody o wymaganej jakości. Ponadto omówiono algorytm i program komputerowy Jakość Wody, stanowiący podstawowe narzędzie analityczne w badaniu niezawodności funkcjonowania monitoringu jakości wody w systemach wodociągowych. Wykazano, że informacje uzyskane w procesie monitoringu dają możliwość przeprowadzenia kompleksowej oceny poziomu świadczonych usług wodociągowych w funkcji ryzyka przekroczenia wartości dopuszczalnych stężeń wskaźników jakości wody.
The available state-of-the-art computer techniques offer the possibility of monitoring how the water supply system functions, as well as analyzing the critical elements of the system, such as the quality of the water being supplied. This paper contains a reliability analysis of the functioning of the water quality monitoring process in a large water supply system (using the municipal water supply system of the city of Wroclaw as an example). Assessments were carried out for the following parameters: rate of occurrence of water quality below standard; average duration of the occurrence of up-to-standard and below-standard water quality in the water-pipe network; probability of supplying water of required quality; availability index and efficiency index of supplying water of required quality. The paper also includes the relevant algorithm and computer program ('Jakosc Wody' - Water Quality), the basic analytical tools for examining the reliability of the functioning of water quality monitoring in the water distribution system. It has been demonstrated that the information obtained from monitoring enables a complex assessment of the quality of the services provided by the waterworks, as it incorporates the risk that the admissible values of the water quality parameters can be exceeded. słowa kluczowe polskie: Jakość wody, monitoring, system dystrybucji wody, niezawodność, ryzyko, wskaźnik gotowości, wskaźnik intensywności.

Monthly reports from June 2017 to May 2018 of Twenty-one wastewater treatment plants in Sharkia were evaluated for the following parameters: temperature, pH, total dissolved solids (TDS), total suspended solids (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), nitrate (NO3), oil and grease (O&G) and Dissolved Oxygen (DO) values. The first aim of this study was to estimate the main wastewater per capita pollution generation per day (PCPL) and found that the 90th percentile PCPL for TSS, COD, BOD, NO3 and O&G were equal to 57.42, 91.59, 59.13, 1.64 and 12.39 (g/capita/day) respectively. The second aim was to assess the performance of the WWTPs in the governorate, by calculating of the wastewater quality index (WWQI) of each plant and for the entire governorate which shows that; 2 WWTPs gives a good performance, 9 WWTPs gives a fair performance, 9 WWTPs gives a marginal performance and 1 WWTP is in bad conditions, the average performance all over the governorate is considered marginal. A simple empirical formula had been established to be used for calculation of the WWQI based on the tested parameters using the multiple linear regression and found to be very effective in predicting the WWQI for the WWTPs.

The results of the study of the macrophytes of the rivers Turia, Vyzhivka and Tsyr, the right-bank tributaries of the upper reaches of the Pripet River, are presented. The species composition of aquatic and coastal aquatic vascular plants was investigated during the vegetation seasons of 2018 and 2019 at 9 observation points located along the rivers from the source to the mouth. The most numerous species composition, 57 species, was found in the Turia River, 36 in the Vyzhivka River, and 28 species were identified in the Tsyr River. The macrophyte index for rivers (Pol.: makrofitowy indeks rzeczny - MIR) was determined from the results, and the ecological state of the rivers was assessed according to the methodology of the macrophyte assessment of rivers (Pol.: makrofitowa metoda oceny rzek - MMOR). The investigation showed that water quality in the Turia River on sites No. 1, 3 and 4 belongs to class III, satisfactory category. The surface water quality on site No. 2 of the Turia River belongs to class II, a good category. The water quality in the Vyzhivka River on all test sites belongs to class II, a good category, which testifies to favourable ecological conditions for the development of higher aquatic plants along the whole course. The water quality in the Tsyr River on test site No. 8 (Kamin-Kashyrskyi, upper course) corresponds to class II, good category. On test site No. 9 (middle course), the quality of surface waters of the Tsyr River worsens to the class III, satisfactory category.

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:
Celem badań było rozpoznanie stanu troficznego wód retencjonowanych w zaporowych zbiornikach kaskady Soły (zbiorniki: Tresna, Porąbka, Czaniec), położonej w obszarach karpackich południowej Polski. Łączna pojemność zbiorników wynosi około 122 mln m3, a powierzchnia zlewni kaskady jest równa 1119 km2. Gromadzone wody są wykorzystywane na potrzeby komunalne i gospodarcze. Na podstawie zmierzonych parametrów fizykochemicznych wód rzeki Soły oraz wód zbiornikowych oceniono stopień ich eutrofizacji. W ocenie wykorzystano normy określone w polskich przepisach prawnych, wskaźnik Carlsona (TSI - Trophic State Index), wskaźnik Neverovej-Dziopak (ITS - Index of Trophical State) oraz normy zalecane przez Organizację Współpracy Gospodarczej i Rozwoju (OECD). Analizy danych z lat 2007-2009 wykazały, że jakość retencjonowanych wód odpowiadała parametrom charakterystycznym dla mezotrofii oraz eutrofii, przy czym najmniej korzystny stan trofii dotyczył najniższego zbiornika kaskady - zbiornika Czaniec. Wskazuje to na potrzebę optymalizacji zagospodarowania przestrzennego zlewni kaskady pod kątem ograniczenia ładunku zanieczyszczeń (zwłaszcza substancji biogennych) dostającego się do wód powierzchniowych.
Water resource protection requires water quality monitoring and assessment. It pertains in particular to mountainous regions with a strategic importance for water supply - a serious threat is posed by nutrients, which cause eutrophication. The main sources of nutrients in mountainous areas are: inappropriate farming methods, erosive run-offs, as well as ineffective wastewater treatment. The aim of the research project was to identify the condition of water resources in cascade dam reservoirs located on the river Sola (reservoirs: Tresna, Porabka, Czaniec). The reservoirs are located in the Polish Carpathians. The combined capacity of the reservoirs in question amounts to about 122 million m3 and their catchment areas cover the area of 1,119 km2. The water resources collected are used for residential and municipal purposes. The degree of eutrophication was established on the basis of physical and chemical parameters of the river Sola and the reservoir water. The assessment referenced the norms specified in the Polish law, Carlson index (TSI - Trophic State Index), Neverova-Dziopak index (ITS Index of Trophical State) as well as Organisation for Economic Co-operation and Development (OECD) norms. The analyses conducted in 2007-2009, revealed that the quality of water resources retained complied with the characteristic parameters of mesotrophic and eutrophic state. Whereby, the least favourable trophic state was identified in the lowest reservoir in the cascade - Czaniec reservoir. The findings imply that the cascade catchment should be managed in such a way that less polluted surface waters are released into the area.

Opis:
The water of Lake Rawa Pening is used as a source of drinking water. Indonesian Government Regulation Number 82 of 2001 on Management of Water Quality and Water Pollution Control stated that the water quality of Lake Rawa Pening should meet the quality standard of first grade and be categorized as no polluted water. The purpose of this research was to assess the water quality based on Indonesian regulation and to assess water quality based on international regulations. The quality of water was assessed using a survey method in 7 sites of the Lake Rawa Pening 3 times for 3 months. Parameters measured were all the water quality parameters required in accordance with Government Regulation No. 82 of 2001. The results indicated that there were 13 values that exceeded the water quality standard of first grade. These exceeded parameters were total suspended solids (TSS), biological oxygen demand (BOD), chemical oxygen demand (COD), orthophosphate (PO4), NO3, As, Se, Cd, Mn, Cu, Pb, H2S, faecal coliform, and total coliform. Water quality status of Lake Rawa Pening was categorized as heavily polluted. The water quality of Lake Rawa Pening should be improved by reducing the pollutants entering the lake by restriction of human activities causing lake pollution.
Woda jeziora Rawa Pening jest wykorzystywana jako źródło wody pitnej. Rozporządzenie rządu Indonezji nr 82 z 2001 r. o zarządzaniu jakością wody i kontroli zanieczyszczeń stwierdza, że woda jeziora powinna spełniać standardy jakości wody pierwszego stopnia i być klasyfikowana jako woda pozbawiona zanieczyszczeń. Celem badań była ocena jakości wody według indonezyjskich i międzynarodowych norm. Jakość wody oceniano w 7 stanowiskach jeziora trzykrotnie w ciągu 3 miesięcy. Mierzone parametry odpowiadały zawartym w rozporządzeniu nr 82 z 2001 roku. Wyniki analiz wykazały, że 13 parametrów przekracza dopuszczalne normy przewidziane dla 1 klasy czystości. Te parametry to: zawiesina całkowita (TSS), biochemiczne i chemiczne zapotrzebowanie na tlen (BOD, COD), fosforany, azotany, As, Se, Cd, Mn, Cu, Pb, H2S, bakterie E. coli i bakterie z grupy coli. Stan wód jeziornych określono jako silnie zanieczyszczone. Jakość wody jeziora Rawa Pening powinna ulec poprawie przez ograniczenie ładunku zanieczyszczeń doprowadzanych do jeziora wskutek działalności człowieka.

Opis:
The objective of the study was to assess the trophic state of water in the hydrographic system of the Sola cascade, situated in the Carpathian region in southern Poland. Analyses included inflowing and retained water in dam reservoirs: Tresna, Porabka and Czaniec. The level of eutrophication of water was estimated basing on its physicochemical parameters. Out of all methods used in determining the trophic state, the selected methods included the norms determined in the Polish regulations, the Neverova-Dziopak index (ITS – Index of Trophical State) and the Carlson index (TSI – Trophic State Index). Analyses of data from years 2007–2009 showed that water quality reflected characteristic parameters for mesotrophy and eutrophy. Unfavorable trophic state concerned almost all waters that were studied, including waters of the lowest reservoir of the cascade – Czaniec reservoir, which is part of the municipal water supply system. That emphasizes the need for protection of the catchment of the cascade with regards to reduction of contamination load discharged to surface waters.
Celem badań było rozpoznanie stanu troficznego wód w systemie hydrograficznym kaskady Soły, położonej w obszarach karpackich Polski południowej. Analizowano wody dopływające oraz retencjonowane w zbiornikach zaporowych: Tresna, Porąbka i Czaniec. Na podstawie parametrów fizykochemicznych wód ustalono stopień ich eutrofizacji. Spośród stosowanych metod ustalania stanu trofii wybrano normy określone w polskich przepisach prawnych, wskaźnik Neverovej-Dziopak (ITS - Index of Trophical State) oraz wskaźnik Carlsona (TSI - Trophic State Index). Analizy danych z lat 2007-2009 wykazały, że jakość wód odpowiadała parametrom charakterystycznym dla mezotrofii oraz eutrofii. Niekorzystny stan trofii dotyczył niemal wszystkich badanych wód, w tym wód najniższego zbiornika kaskady - wodociągowego zbiornika Czaniec. Wskazuje to na potrzebę ochrony zlewni kaskady pod kątem ograniczenia ładunku zanieczyszczeń dostających się do wód powierzchniowych.

Opis:
Organizmy fitoplanktonowe wykorzystywane są w monitoringu biologicznym wód powierzchniowych. Badania wód dwóch rzek o zróżnicowanym stopniu antropopresji, Narwi i Biebrzy, wskazały na celowość ich wykorzystania w ocenie zmian jakości. Analiza składu jakościowego zbiorowisk fitoplanktonu wykazały ścisłą zależność od chemizmu wody. Na jakość wód rzeki Narwi wpływa Zbiornik Siemianówka, który powoduje wzrost trofii i pogorszenie jakości wody. Zmniejszanie różnorodności fitoplanktonu wzdłuż biegu rzeki oraz wzrost liczebności zielenic i okrzemek, wskazuje na stopniową poprawę jej jakości. W rzece Biebrzy stwierdzono natomiast mniejszą liczebność i różnorodność fitoplanktonu niż w rzece Narwi. Zmiany w jakości wody oraz w zbiorowiskach glonów stwierdzono na odcinkach intensywnego wypasu bydła, bliskiego sąsiedztwa gospodarstw rolnych i zróżnicowanej szybkości przepływu.
Phytoplankton taxons are used in biological monitoring of freshwaters. The studies of two rivers with varied anthropopressure degree, the Narew and the Biebrza rivers, indicated a purposeful use of both of them for assessing fresh water quality changes. Analysis of phytoplankton taxonomic composition showed itc strict dependence on water quality. The Siemianówka Reservoir has an impact on the Narew river water by increasing trophj and decreasing water quality. Decreasing phytoplankton diversity and an increase of euglenoids and diatoms number along the river length, point to a gradual improvement of water quality. In the Biebrza river, a lower number and diversity of phytoplankton than in the Narew river were observed. Changes in water quality and in algae composition were found in the regions of intensive cattle grazing, and in the neighborhood of farms as well as at reaches with a diversified flow velocity.

Przedstawiono badania mikroflory (fitobentosu i planktonu) w akwenie powstałym w wyniku wydobycia piasku w miejscowości Biestrzynnik (województwo opolskie). Wyrobisko nie jest miejscem wypoczynku i rekreacji. Było jedynie przez kilka lat udostępnione dla wędkarzy. Akwen ma dobrze rozwiniętą strefę brzegową, a w wodzie występuje wiele atrakcyjnych dla wędkarzy gatunków ryb. Pobierano próbki do badań mikroskopowych. Udział gatunków wskaźnikowych wynosił 50%. Należały one do: Bacillariophyceae, Chlorophyta, Cyanophyceae i Chrysophyceae. Wśród nich przeważały gatunki z grupy ekologicznej saproksenów. Bardzo liczne populacje w próbkach pięciostopniowej skali miały: Cymbella ventricosa, Navicuła radiosa, Cocconeis placentula, Nitzschia acicularis, Nitzschia hungarica, Cosmarium botrytis. Glony należały głównie do grupy saproksenów i pojedynczo do saprofili. Badany akwen ma walory przyrodnicze, estetyczne oraz rekreacyjne.
The paper presents the results of the researching of microflora (phytobenthos and plankton) in the water region created after extraction of sand in the locality of Biestrzynnik. The excavation is not a place for rest and recreation. It used to be available for anglers only for a period of several years. The water region has a well developed littoral żone and numerous species of fish attractive for anglers are found in its waters. Samples for microscopic examination of water were collected. The participation of indicatory species was 50%. They belonged to Bacillariophyceae, Chlorophyta, Cyanophyceae and Chrysophyceae. Among them, species from the ecological group of saproxenes were dominant. With regard to adopted 5-degree scale, Cymbella yentricosa, Nitzschia hungarica, Navicula radiosa, Cocconeis placentula, Nitzschia acicularis, Cosmarium botrytis had very large population. The algae mainly belonged to the group of saproxenes and few to saprophiles. The examined water body has natural, aesthetic and recreational values.

Opis:
The paper presents an assessment of the water quality of the Vistula river and its tributaries in selected municipalities in the Cieszyn district based on benthic macroinvertebrates. A total of 45 samples were taken on nine positions. Most of the collected individuals were identified to the family level, except: Heptageniidae which was diagnosed to the genus; Turbellaria and Oligochaeta identified into the class. The conducted research showed that 54 taxa of benthic macroinvertebrates occurred at the analyzed sites. Among them, 40 taxa have a bioindicative value. The most sensitive to pollution are mayflies from the family Ameletidae and caddisflies from the families Glossosomatidae, Leptoceridae and Beraeidae. However, their frequency and density at the study sites was very low. The families Ephemerellidae, Heptageniidae, Hydropsychidae and Polycentropodidae as well as annelids from the Oligochaeta class were much more frequent. Based on macrozoobenthos diversity data, two biological indices were calculated: BMWP-PL index and Margalef's biodiversity index. The values of these biological indicators was using to the classiffication of water into the appropriate quality class. The final classification showed that the examined sections of the Vistula river represents the I, II and III class of water quality what indicated high, good and moderate ecological potential/state. The first class of water quality in terms of both indices was recorded at the sites located in Ustroń, Skoczów and Drogomyśl. For these positions, the value of the BMWP-PL index was over 100, while the value of the Margalef's index was in the range of 6.26-7.17.The lowest, third class of water quality was found in Kiczyce and Ochaby Wielkie. In these places, the diversity of macroinvertebrates was the lowest, which was reflected in the low values of both studied indices (BMWP-PL: 40; 41, Margalef's index: 2.6; 3.37).

W wodach czterech jezior Pomorza Zachodniego badano kinetyczne parametry określające aktywność alkalicznej fosfatazy (APA). We wszystkich badanych jeziorach APA była wyższa w warstwie naddennej w porównaniu z warstwa powierzchniową, szybkość maksymalna reakcji hydrolizy związków organicznych fosforu katalizowanej przez fosfatazy była ponad dwa razy wyższa w warstwie naddennej. Największą szybkość maksymalną (vmax) i najniższe wartości stałej Michaelisa-Mentcn (KM) odnotowano w wodach jezior Dołgie Myśliborskie i Zaborsko, w których występowały największe letnie braki fosforu, które fitoplankton mógł kompensować przez wzrost produkcji enzymów.
Kinetic parameters of alkaline phosphatase activity (APA) were studied in waters of the four lakes in Western Pomerania. APA was higher in near-bottom waters in all the lakes, maximum rate of the hydrolysis of organic phosphate compounds was over twice higher than in the surface waters. The highest maximum rate (vmax) and the lowest Michaelis-Menten constant (KM) values were observed in surface waters of Dołgie Myśliborskic and Zaborsko Lakes, where the strongest summer phosphorus depletion occurred. Phytoplancton could compensate their phosphorus deficiency by increasing enzyme production.

Opis:
Changes in ecological status of the lower Vistula River over the past two decades were evaluated. The 1990s saw dynamic changes in the Polish economy and increasing environmental awareness, accompanied by introduction of modern, effective treatment methods of wastewater discharges into rivers. Yet, extensive research on modern evaluation of aquatic ecosystems was only conducted in the first decade of the 21st century. Planktonic diatoms (mainly of the Centricae subclass) followed by coccal chlorophyta were the main groups determined to form the phytoplankton biomass in the Vistula River in Torun. A more significant contribution of other algal groups (including cyanobacteria) is only occasional. Application of phytoplankton multimetric index (IFPL) for rivers allowed assessment of water quality variations in the Vistula River. Phytoplankton of the Vistula River determined in the ‘90s was compared with that of the period of 2007–2015. The trophic index (TI) measured in the 90’s indicated poor ecological status of the river. Its value for both years of research (1994 and 1998) was 0.35. Over the subsequent twenty years the water quality significantly improved. Today, the TI value is 0.66, while the average phytoplankton multimetric index is 0.75, indicating good ecological potential of the Vistula River in Torun.
Dokonano oceny zmian potencjału ekologicznego dolnej Wisły w ciągu ostatnich dwudziestu lat. Lata dziewięćdziesiąte ubiegłego wieku charakteryzowały dynamiczne zmiany w gospodarce Polski, zwiększenie świadomości ekologicznej, a wreszcie wprowadzenie nowoczesnych i skutecznych metod oczyszczania ścieków odprowadzanych do rzek. Szerzej zakrojone badania nad nowoczesną oceną ekosystemów wodnych wykonano dopiero w pierwszej dekadzie XXI wieku. Przeprowadzona analiza wykazała, że o biomasie fitoplanktonu Wisły na wysokości Torunia decydują okrzemki planktonowe, głównie z podklasy Centricae. Drugą ważną grupą są zielenice kokkalne. Znaczący udział innych grup glonów (w tym także sinic) jest sporadyczny. Zastosowanie multimetrycznego wskaźnika fitoplanktonowego (IFPL) w przypadku rzek umożliwiło ocenę zmian jakości wody w Wiśle. Fitoplankton Wisły z lat dziewięćdziesiątych został porównany z fitoplanktonem w latach 2007–2015. W latach dziewięćdziesiątych XX wieku wartości wskaźnika trofii wskazywały na zły potencjał ekologiczny. W obu latach badań (1994, 1998) wartość ta wynosiła 0,35. Jakość wody po 20 latach uległa znacznej poprawie. Obecnie wartość wskaźnika trofii (IT) wynosi 0,66, natomiast średnia wartość wskaźnika fitoplanktonowego (IFPL) wynosi 0,75, co wskazuje na dobry potencjał ekologiczny wód Wisły w przekroju Torunia.

Opis:
W pracy przedstawiono wyniki badań składu gatunkowego wodnych makrofitów rzeki Turia, biegnącej na terytorium Polesia Wołyńskiego. Inwentaryzację roślin przeprowadzono w czterech punktach obserwacyjnych, począwszy od źródła do ujścia rzeki, w okresie od maja do września 2017 roku. Oznaczono 59 gatunków roślin, w tym 41 gatunków wskaźnikowych i obliczono Makrofitowy Indeks Rzeczny (MIR) dla rzeki Turia zgodnie z "Makrofitową Metodą Oceny Rzek”. Ustalono, że stan ekologiczny wód w górnym biegu rzeki (wieś Zaturce) jest umiarkowany, w średnim biegu rzeki (miasto Kowel - stanowisko koło mostu) wzrasta do stanu dobrego, natomiast na następnych stanowiskach pogarsza się i w pobliżu wsi Bachiw oraz we wsi Buzaky (dolny bieg rzeki) ponownie osiąga stan umiarkowany.
The results of the study of the species composition of the aquatic macrophytes of the Turija River, passing through the territory of the Volyn Polissya, are presented. The research was carried out on four observation points, from May to September 2017, along the river - from the river source to the river mouth. In total, 59 plant species were identified, including 41 species regarded as indicators of environmental conditions. The paramater known as «Makrofitowy Indeks Rzeczny (MIR)» was also calculated. It was found that the ecological condition of the water in upper part of the river (Zaturtsi village) is satisfactory, in the middle part of the river (Kovel, near the bridge) becomes better. In the next research points, such as the Bakhiv village, in the lower part of the river, and near the Buzaky village will reach the level of condition as satisfactory.

This study assesses quality of water resources of Mohammedia prefecture. Design/methodology/approach: The water quality analysis was carried out based on physio-chemical and heavy metal concentrations. The physio-chemical analysis comprised of status of concentration, overall quality and water pollution index evaluation. The heavy metal evaluation consisted of Ecological Risk Index, non-carcinogenic risk and carcinogenic risk assessment. Findings: The landfill near Ben Nfifikh River reported insignificant (WPI<1) – low level of pollution (>1≤1.5) for surface and groundwater points. However, the groundwater for Zenata region was found to pose both carcinogenic (CRt > 0.0001, range 0.4-35.31) and non-carcinogenic risks (HQ>1, range 6 -34) of higher degree rendering it unfit for human consumption. Hence, this study concludes that groundwater resources should not as water supply; instead, Oud El Maleh River can serve as surface water source for meeting requirements of Zenata region. Research limitations/implications: The data obtained can be categorized as landfill area near river Nfifikh and landfill area near river El Maleh. Both areas have been investigated for groundwater and surface water quality assessment. Practical implications: This study demonstrates the need to study the characteristics of groundwater (depth, flow rate, water renewal, etc.) before arranging a waste dump. This problem is especially relevant for arid countries, since residents experience a shortage of water, as well as a lack of rainfall provides a weak renewal of groundwater, which can contribute to the accumulation of a higher concentration of carcinogens in groundwater and provide a high risk to public health. If policymakers in arid countries and decision-makers have effective water quality maps, then the country can be more efficiently managed water resources without risking the population. Originality/value: The current study is planned as a multi-stage, each of which is supposed to conduct field studies of groundwater and surface water quality with appropriate parameters, analysis of institutional reports and related scientific studies in order to create an effective water quality map for rational water use.

Opis:
The environmental assessment of the surface water quality of the Western Bug River has been made using the system of classification quality of land surface water of Ukraine in accordance with the approved methodology, which allows comparing water quality of separate areas of water objects of different regions. The calculation of the environmental assessment of water quality has been carried according to three blocks: block of salt composition, block of trophic and saprobic (ecological and sanitary) indicators and block of indicators of content of specific toxic substances. The results are presented in the form of a combined environmental assessment, based on the final conclusions of the three blocks and consists in calculating the integral ecological index. Comprehensive studies of changes in the water quality of the Western Bug River have been conducted within the territory of Ukraine for a long-term period. The water quality of the river on the final values of the integral indicators of the ecological condition corresponded mainly to 4nd category of the 3rd class – the water is “satisfactory” by condition and “little polluted” by degree of purity (except for points of observation that located within the Volyn region, where the water quality corresponded to 3rd category and the 2nd class. It is “good” by condition and “fairly clean” by the degree of purity). Visualization and part of the analysis are performed using GIS technologies in the software of the ArcGIS 10.3.
Środowiskową ocenę jakości wód powierzchniowych Bugu prowadzono z zastosowaniem systemu klasyfikacji wód powierzchniowych Ukrainy w zgodzie z przyjętą metodologią, która umożliwia porównywanie jakości wód odrębnych obszarów z różnych regionów. Obliczenia prowadzące do oceny jakości wody prowadzono w trzech blokach: blok składu mineralnego wód, blok wskaźników troficznych i saprobowych (ekologicznych i sanitarnych) oraz blok wskaźników substancji szczególnie toksycznych. Obliczono zintegrowane wskaźniki ekologiczne i przedstawiono je w formie zbiorczej oceny środowiskowej opartej na wnioskach z trzech wymienionych bloków. Całościowe badania zmian jakości wody w Bugu są prowadzone na terytorium Ukrainy od wielu lat. Zintegrowane wskaźniki odpowiadają w większości 4. kategorii i 3. klasie – woda ma stan „zadowalający” i jest „nieznacznie zanieczyszczona” (z wyjątkiem stanowisk w regionie Wołynia, gdzie jakość wody odpowiada 3. kategorii i 2. klasie. Jej stan jest „dobry” a woda jest „dość czysta”). Wizualizację i część analiz wykonano z zastosowaniem technologii GIS i programu ArcGIS 10.3.

Opis:
W październiku 2017 roku pobrano próby makrozoobentosu na sześciu stanowiskach w górnych partiach rzeki Wisłoki. Na ich podstawie dokonano oceny jakości wody i przypisano im klasy posługując się metodą BMWP-PL oraz indeksem Margalef’a. Jakość wód Wisłoki jest niezadowalająca – najczęstszym wynikiem oszacowania jakości jest III i IV klasa. Wynik ten jest znacznie gorszy niż oszacowanie tą samą metodą jakości wody górnych partii rzeki Jasiołki i rzeki Ropy. Rzeki te są podobne fizjograficznie i usytuowane w pobliżu Wisłoki.
In October 2017, macrozoobenthos samples were collected on six positions in the upper parts of the Wisłoka River. Based on them, the quality of water purity was assessed and the purity classes were assigned to them using the BMWP-PL method and the Margalef index. The quality of waters in Wisłoka is unsatisfactory - the most common result of the quality assessment is the 3rd and 4th water purity class. This result is much worse than the assessment of the water quality of the upper parts of the Jasiołka River and the Ropa River using the same water quality method. These rivers are similar physiographically and situated near Wisłoka.

Opis:
W pracy przedstawiono wybrane wyniki oceny jakości wód rzecznych w systemie Narwi. Badania te stanowią integralną część szerokiego projektu badawczego, którego celem było określenie wpływu użytkowania zlewni na transport substancji rozpuszczonych w wodach Narwi i wybranych jej dopływów. W pracy dokonano (a) rozpoznania środowiska przyrodniczego zlewni oraz źródeł dostawy substancji chemicznych do wód płynących; (b) analizy mechanizmów odpływu wód i substancji rozpuszczonych w warunkach zróżnicowanej gospodarki agrarnej oraz (c) określenia jakościowych i ilościowych zmian dokonujących się w chemizmie wód jako skutku warunków istniejących w badanych zlewniach. Przedstawione w pracy jakościowe charakterystyki są efektem procesów, które rządzą zasilaniem koryta rzecznego w systemie o zróżnicowanych warunkach przyrodniczych oraz rolniczej działalności człowieka. Występujące zmiany jakości wody wzdłuż profilu podłużnego Narwi są rezultatem bezpośrednich dostaw zanieczyszczeń oraz z systemów niższych rangą taksonomiczną. Ze względu na średnią zawartość wskaźników ogólnego zanieczyszczenia substancjami organicznymi (BZT₅, ChZT) jakość wód Narwi oraz dopływów (Biebrzy, Pisy, Rozogi i Omulwi) różnicowała się od I (bardzo dobrej) do IV (niezadowalającej) klasy jakości.
Paper presented chosen results of the water quality assessment in the Narew river system. The study is an integral part of the wide research project aimed at the affect of land use on the transfer of dissolved substances with the Narew river and its tributaries. The paper contains: (a) recognition of natural environment of the basin and sub-basins and the sources of chemical substances entering flowing water; (b) analyses of outflows mechanisms of water and dissolved substances under conditions of diversified agricultural management; (c) seasonal changes in quality and quantity of water resulted from individual characteristics of the basins. Presented data concerning water quality are affected by the processes of riverbed supply with water under diversified environmental conditions and human agricultural activity. The changes in water quality occurring downstream the longitudinal profile of Narew river resulted from direct contamination, as well as from the water systems of lower taxonomical level. Due to average content of organic pollutants (BOD₅, COD), the water quality of Narew river and its tributaries (Biebrza, Pisa, Rozoga, Omulew) ranged from the Ist class of water purity (very good) to the IVth class (unsatisfactory).

Opis:
This study was carried out to determine the water quality of the beaches at Matrouh, south-eastern Mediterranean Sea, Egypt, by studying environmental variables as well as phytoplankton abundance and community structure. Surface water samples were monitored from a series of beach sites over a period of five seasons during 2009–2010. A total of 203 phytoplankton species were identified from seven algal divisions. Seasonal differences in the quantitative and qualitative composition of the phytoplankton communities in the different sites were marked. Nutrient concentrations and phytoplankton abundances were found to be poorer than those of many other areas along Egyptian coast. The Shannon-Wiener Diversity Index classified Matrouh water as being between clean and moderately polluted, whereas the WQI demonstrated that it was between good and excellent. It can be concluded that the index based onWQI is currently more suitable than the phytoplankton species index for assessing the quality of the water of the Matrouh beaches.

Opis:
W niniejszym artykule Autorzy przedstawili analizę warunków hydrologiczno-środowiskowych w aspekcie lokalizacji małej elektrowni wodnej na rzece Budkowiczance. Zlewnia rzeki Budkowiczanki wynosi A=232 km2 i znajduje się w południowo–zachodniej Polsce w województwie opolskim. Długość rzeki Budkowiczanki wynosi ok. 60 km. Autorzy zaproponowali lokalizację małej elektrowni wodnej na jazie w km 20,142 jej biegu w miejscowości Okoły-Kupi Las w gminie Murów. Badany przekrój należy zaliczyć do jednolitej części wód powierzchniowych „Budkowiczanka od Wiszni do Stobrawy”. Planowany na cele małej energetyki wodnej jaz zlokalizowany jest w odległości około 1,7 km powyżej wodowskazu Krzywa Góra. Przeanalizowano warunki hydrologiczne w rzece Budkowiczance dla profilu wodowskazowego Krzywa Góra. Na potrzeby hydrotechniki, dla rzeki Budkowiczanka, w przekroju wodowskazowym Krzywa Góra, wyznaczono stany i przepływy charakterystyczne obejmujące okres 1981-2015. Dla poszczególnych rocznych sum opadów z wielolecia 1981-2015, dla stacji Opole zlokalizowanej w pobliżu zlewni rzeki Budkowiczanki wyznaczono lata bardzo suche i suche. Dla tych lat wyznaczono miary odpływu takie jak: współczynnik odpływu, wysokość warstwy odpływu, objętość odpływu. Wyznaczono również moc teoretyczną elektrowni, w oparciu o przepływ średni w wybranych latach oraz przepływ najdłużej trwający. W badanym cieku stwierdzono występowanie ośmiu gatunków ryb. Po względem elementów: biologicznych, hydromorfologicznych i fizykochemicznych z lat 2012 i 2015, potencjał ekologiczny JCWP jest jedynie umiarkowany, a tym samym stan jednolitej części wód – zły.
In this article, the Authors presented an analysis of hydrological and environmental conditions in the aspect of the location of a small hydropower plant on the Budkowiczanka River. The catchment of the Budkowiczanka River is A = 232 km2 and it’s located in south-western Poland in the Opolskie Province. The length of the Budkowiczanka River is about 60 km. The authors proposed the location of a small hydropower at 20,142 km of its run in Okoły-Kupi Las in the Murów commune. The analyzed cross-section should be included in the body of surface water „Budkowiczanka from Wisznia to Stobrawa”. The weir planned for the purposes of small hydropower is located approximately 1.7 km above the Krzywa Góra gauging station. Hydrological conditions were analyzed in the Budkowiczanka River for the Krzywa Góra profile. For the hydrotechnic purposes states and discharges were determined. Based on the annual sums of precipitations for the Opole station, from the multi-year period of 1981–2015, very dry and dry years have been designated. This station is located near the Budkowiczanka River catchment. For these years, outflow measures were determined such as: outflow coefficient, height of the outflow layer, outflow volume. The theoretically available power of the hydropower plant was also determined, based on the average flow and the longest running flow in the selected years. In the studied river, eight species of fish were found. In terms of biological, hydromorphological and physicochemical elements from year 2012 and 2015, the ecological potential of surface water body is only moderate, and thus the status of water body is bad.

Opis:
In this paper we consider the impact of Human Development Index and Environmental Health on sustainable development in 178 observed countries. We focus on the necessity of multidisciplinary approaches that estimate and predict how selected indicators such as (1) Improved sanitation facilities (% of population with access); (2) Life expectancy at birth, female (years); (3) Improved water source, rural areas (% of rural population with access); (4) Access to electricity (% of population), and (5) Health expenditure per capita (current USD) influence on sustainable development and environmental health in the World. The Environmental Health and Human Develop-ment Indicator allow countries to compare their social and environmental inequalities with other surrounding countries/regions. Any correlations between Environmental Health and Human Development Index as well as with five World Bank indicators were to be analyzed. The objective was also to explore the heterogeneity of observed countries according to their level of sustainable development based on Environmental Health and Human Devel-opment Index.
W artykule przedstawiono wpływ wskaźników Rozwoju Społecznego (Human Development Index, HDI) i Zdro-wia (Environmental Health, EH) na zrównoważony rozwój w 178 krajach. Szczególny nacisk położono na (1) Poprawę dostępu do urządzeń sanitarnych (% populacji z dostępem); (2) Oczekiwany czas życia od momentu urodzenia u kobiet (w latach); (3) Poprawa dostępu do wody na terenach rolniczych (% populacji z dostępem); (4) Dostęp do elektryczności (% populacji) oraz (5) Wpływ poziomu wydatków na zdrowie na osobę (w USD) na zrównoważony rozwój i kwestie zdrowotne w perspektywie światowej. Wskaźniki (w połączeniu z tym przygoto-wanymi przez Bank Światowy) te pozwalają na porównanie różnych krajów w zakresie ich społecznych i środo-wiskowych nierówności wobec siebie i innych krajów/regionów. Przeanalizowano wszelkie występujące korelacje pomiędzy wskaźnikami. Celem było także zbadanie poziomu heterogeniczności poszczególnych krajów z per-spektywy poziomu wdrażanego rozwoju zrównoważonego z uwzględnieniem wskaźników Rozwoju Społecznego (HDI) i Zdrowia (EH).

Opis:
Ocena strat ekologicznych, jakie powodują ścieki odprowadzane do wód powierzchniowych, stanowi podstawę do ustalenia efektu środowiskowego osiąganego dzięki oczyszczaniu ścieków. Ten efekt jest określany jako wartość strat unikniętych w środowisku wodnym dzięki odprowadzaniu do niego ścieków oczyszczonych. Oszacowanie tych strat nie jest łatwe i wymaga wcześniejszego ustalenia strat jednostkowych. W tym celu przeprowadzono analizę trzech metod szacowania wartości jednostkowego wskaźnika strat spowodowanych zanieczyszczeniem wód powierzchniowych – metody wskaźnikowej, metody wyceny warunkowej oraz metody ceny cienia. W rezultacie wykonanej analizy określono zalety i wady każdej z nich oraz oceniono możliwości ich stosowania w polskich warunkach. Wykazano, że metoda wskaźnikowa umożliwia szacowanie, na podstawie danych literaturowych, ogólnokrajowego wskaźnika jednostkowych strat spowodowanych zanieczyszczeniem wód powierzchniowych. Z kolei metoda wyceny warunkowej pozwala oszacować, na podstawie badań ankietowych, wartość tego wskaźnika w przypadku pojedynczej gminy. Metoda ceny cienia umożliwia natomiast określenie jednostkowego efektu środowiskowego, którego wartość odpowiada wskaźnikowi jednostkowych strat unikniętych w środowisku wodnym w rezultacie oczyszczania ścieków. W przypadku tego wskaźnika określono strukturę wpływu poszczególnych grup zanieczyszczeń zawartych w ściekach (azot, fosfor, zawiesiny, związki organiczne) na efekt środowiskowy. Wykazano, że największy wpływ na ten efekt ma usunięcie ze ścieków związku azotu i fosforu. Z porównania metod określenia wartości wskaźnika jednostkowych strat spowodowanych zanieczyszczeniem wód powierzchniowych wynika, że ze względu na dokładność oszacowania i możliwości określenia wartości i struktury wskaźnika jednostkowych strat w przypadku pojedynczej oczyszczalni ścieków, największe możliwości daje metoda ceny cienia.
Assessment of ecological losses caused by surface water contamination forms the basis for establishing the environmental benefit of wastewater treatment. This benefit is defined as the amount of losses avoided in the aquatic environment due to treatment of the discharged wastewater. Estimation of these losses is quite complex and requires prior determination of unit loss indexes. To this end, an analysis of the three methods for estimating the index value of the unit loss caused by surface water pollution was conducted, i.e. the index method, the contingent valuation method and the shadow price method. As a result, the advantages and disadvantages of each method were determined as well as their applicability under local Polish conditions was assessed. Based on literature data, the index method makes it possible to estimate the nationwide index of unit losses caused by surface water pollution. The contingent valuation method, on the other hand, allows estimation of the index value for a single municipality on the basis of interview surveys. Finally, the shadow price method facilitates determination of the unit environmental benefit, the value of which corresponds to the index of the unit loss avoided in the aquatic environment in consequence of wastewater treatment. For the latter, the structure of impact on environmental benefits of particular pollutant groups from the wastewater (nitrogen, phosphorus, suspended solids, organic compounds) was determined. The removal of nitrogen and phosphorus compounds was demonstrated to have the greatest effect. The comparison of methods for estimating the index values of unit losses due to water pollution demonstrated the shadow price method to have the highest potential in terms of its accuracy and capacity to estimate size and structure of the unit loss index for a single wastewater treatment plant.
