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.

Opis:: 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 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.

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 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.

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:: 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:: 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:: 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:: 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.

Opis:: 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:: 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:: 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 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).
