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

Opis:
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:
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.

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.

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.

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.

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.

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 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.

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.

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.

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).

Opis:
Purpose: Water is vital for the sustenance of every life form. Urbanization, growing population and industrial development has led to exploitation of water resources globally. 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:
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:
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.
