Evaluation of Water Quality and Sustainability of Treated Wastewater for Irrigation and the Municipal Uses in Karbala Province

This study was conducted to assess the quality of treated wastewater from the wastewater treatment project in Karbala. and its reuse for irrigation and municipal by Canadian Water Quality Index (CWQI). Samples were collected periodically with three replications from (Dec. 2021 –Jul.2022). The results showed that the water was characterized by high salinity, TDS, TSS, total hardness, EC, and turbidity, which were recorded at 2039 -3739 mg/l; 1030-2640; 30-48 mg.L-1. 3740 -2040 µs/cm and 3.17 -8.5 NTU respectively, major cations and anions (Cl-, PO4-3, NO3-, S2O4-2 and K+) exceed significantly to (57-380; 0.003-4.99; 8.63-44.25; 453-1340; 4.537) mg. L-1, sodicity index (SAR, Na+ and Sodium percentage ratio) and magnesium hazard, were detected 0.59 – 4.89; 138-447.5 12.98-43.76), Water can be classed depending on that as a permit to good. However, it’s categorized as marginal-fair according to the CCME Water quality index, especially in the far station from the plant water. Principal Component Analysis (PCA) showed depending on its effect on the value of the index, where the first group PCA1 recorded the largest proportion (35.26%) and includes dissolved solids, EC, salinity, Na, SAR, Na%, alkalinity, SO4, pH, DO, BOD5 Mg risk of magnesium. The second group, PCA2, with the lowest percentage (18.78%), was represented by temperature, Ca+2, total hardness, K, Cl, PO4, NO3, TSS, and turbidity. This water is a wealth that can be exploited in the cultivation of the desert adjacent to Karbala governorate, and by adopting different methods to reduce the effect of salinity.

Impact of industrial hotspots on Tamla nala and Nunia nala confluence - a tributary of the Damodar river.

Clean water is essential for drinking, household use, and agriculture. Researchers studied 39 sites near Tamla nala and Nunia nala channels in Durgapur and Asansol City (West Bengal) to assess the deterioration level of water due to industrial discharge. During the first phase out of three, the researchers conducted a spatial representation of various physicochemical parameters, such as temperature, pH, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total Hardness (TH), Electrical Conductivity (EC), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), significant anions such as chloride (Cl-), nitrate (NO3-), phosphate (PO4-3), sulfate (SO42-), cyanide (CN-1) and fluoride (F-), as well as heavy metals/metalloids such as lead (Pb), cadmium (Cd), chromium (Cr), iron (Fe), copper (Cu), nickel (Ni), mercury (Hg) and arsenic (As). As observed the parameters at various sites along the stream exceeded threshold limits majorly due to industrial discharge: highest pH, TDS, TH, EC, Cl-, SO42- at site 26; Fe at site 1, TSS, COD, CN- at site 33, 31, 2 respectively; Cd, Ni, Cu at site 19; Hg and Pb at site 3 and As at site 20. Contaminated areas were marked in red and secure areas in green. Additionally, the HMPI (Heavy metal pollution index) was estimated for eight locations to understand the impact of heavy metal pollution in the second phase of the study. An extremely high HMPI indicates heightened toxicity and health risks for both residents and outsiders. The Canadian Water Quality Index (1.0) was calculated for eight sites in the third phase based on seventeen parameters. The resulting WQI value was below 44, indicating poor water quality at the sites. Due to the poor quality and critical heavy metal toxicity, the authors recommended continuous monitoring, strict regulation enforcement, increased treatment capacity, Zero Liquid Discharge implementation, and raising awareness among residents.

Water Quality Assessment of AL-Mahawil Stream/Babylon/Iraq Using Canadian Water Quality Index

This study aimed to know the water quality in Al-Mahawil stream which is a stream from Euphrates River in Babylon governorate by using Canadian water quality index by determining the values of the most important physical and chemical parameters in water stream after taken three study sites along the stream [site 1 (S1), site 2 (S2), site 3 (S3)]. the data was determined seasonally after collection the samples monthly from December 2021 to November 2022. The results first finding out whether the values of these parameters within or above of Iraqi limiting standards of drinking water after that the Canadian water quality index (WQI) has been calculation, then determined if water stream can possibly directly used for drinking purpose or other uses. Generally, results pointed that some of physical and chemicals parameters were in Iraqi permissible limiting of drinking water, while others parameters were above Iraqi limiting standard. Also, the results showed that WQI for Al-Mahawil stream after used all study parameters for calculating was marginal and cannot used directly for drinking purpose. Also, results showed there was a significant differentiation among some parameters with positive correlation coefficients among it.

Application of selected groundwater quality indices in anthropogenically transformed areas

Correctly assessing the impact of waste landfills on groundwater quality requires the development and use of comprehensive tools that consider the content of individual components in water, as well as those relating to the hydrochemical background. The article presents a comparative analysis of selected water quality indices used around the world to assess the environmental threat caused by sources of pollution. The paper includes the following indicators: Water Quality Index, Landfill Water Pollution Index, Nemerow Pollution Index, Backman Index, Canadian Water Quality Index, Horizontal Ratio, Enrichment Factor and Fuzzy Water Quality. Attention was paid to the values of individual indices, their applicability in municipal and industrial waste landfills, and limitations in their use. A literature review has proven that some indices, such as the Landfill Water Pollution Index and Nemerow Pollution Index, are used very often as they provide reliable results. Index methods help conduct rational water management, complement groundwater quality monitoring, and serve as a tool for making decisions in various water protection areas.

Water Quality Evaluation of Tigris River by using Canadian and Horton Water Quality Index

Water quality index (WQI) is a simplified and explicable number calcuated from data on tested prameters in water. In this study, two methods for calculating water quality index (WQI) were used to assess the water quality of Tigris River using monthly data from 2011 to 2013. The data were collected at four different gauging stations. Two gauing stations are located on Tigris River at upstream in Mosul city while the other two downstream gauging stations are located on Tigris River at downstream in Al-Amarah city. The Canadian Council of Ministers of the Environment’s (CCME WQI) and Horton (Horton’s WQI) methods were applied to assess the water quality of Tigris River at the selected stations. The data used in the assessment included several parameters such as calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), chloride (Cl), sulfate (SO4), bicarbonate (HCO3), nitrate (NO3), total dissolved solid (TDS), biochemical oxygen demand (BOD5) and electric conductivity (EC). According to the values of CCME WQI mehod, the quality of Tigris River in Mosul city was at a good level (the values of WQI were varied from 83 to 94) while it and falls under the marginal category in Al-Amarah city (the values were varied from varied from 52 to 59). However, the application of Horton’s WQI method showed that the quality of Tigris River in Mosul city was fluctuated from excellent to good (values of WQI varied from 24 to 80 per month) while it was poor in Al-Amarah city (values of WQI varied from 74 to 160 per month). In conclusion, the Horton’s WQI method was found more relastic when used to assess the water quality of Tigris River compared with CCME WQI method.

Biological and Ecological Monitoring Using Epiphytic Diatoms on Two Aquatic Plants to Estimate the Water Quality of Habbaniyah Lake, Western Iraq

The current study was conducted in Habbaniyah Lake in Anbar Governorate - western Iraq, starting from February 2022 tol July 2022. Five sites were chosen to collect water samples and epiphytic diatoms attached to two aquatic plants, Phragmites australlis (Cav.) Trin. and Ceratophylum demsrsam L.. The current study aims to employ the quality and quantity of the epiphytic diatoms community attached to the host aquatic plants to estimate the quality of the lake water, by conducting a set of environmental indicators that included biological indicators. 102 species of Bacillariophyceae class were identified. Where 84 species were diagnosed on the Ceratophyllum, while 61 species were diagnosed on the Phragmites In the current study, a set of ecological indices was conducted to characterize the water quality of Habbaniyah Lake, which included three biological indices: the Tolerance Pollution Index (PTI), where the lake was described as moderately polluted, to record values whose averages ranged (1.65-2.35), and Trophic Diatomic Index (TDI), whose average values ranged from (55.62 - 58.72), where the lake was described as mesotrophic and Shannon Diversity Index, where the waters of Lake Habbaniyah were described as having medium biodiversity, recording average values (2.22 - 2.50). An environmental index was conducted, which is the Canadian Water Quality Index (CCME), where it recorded values that ranged from (76.59 - 78.66), where the lake water was described as of moderate (Fair) quality and often threatened or weak from time to time, and the water condition deviates from the required level. or desired.

New model of long-term changes in spatiotemporal patterns of water quality across Shatt-Al-Arab River by applying GIS technique, from 1976 to 2020

PurposeUsing a combination of the geographical information system (GIS) and the Canadian water quality index (WQI), the current study sought to provide a long-term general assessment of the water quality of the Shatt Al-Arab River (SAAR), focusing on its suitability for living organisms. Likewise, SPSS statistics was used to develop a nonlinear WQI regression model for the study area.Design/methodology/approachThe study required four decades of data collection on some environmental characteristics of river water. After that, calculate the WQI and conduct the spatial analysis. Eight variables in total, including water temperature, dissolved oxygen, potential hydrogen ions, electrical conductivity (EC), biological oxygen demand, turbidity, nitrate and phosphate, were chosen to calculate the WQI.FindingsThroughout the study periods, the WQI values varied from 55.2 to 79.83, falling into the categories of four (marginal) and three (fair), with the sixth period (2007–2008) showing the most decline. The present research demonstrated that the high concentration of phosphates, the high EC values, and minor changes in the other environmental factors are the major causes of the decline in water quality. The variations in ecological variables' overlap are a senior contributor to changes in water quality in general. Notably, using GIS in conjunction with the WQI has shown to be very effective in reducing the time and effort spent on investigating water quality while obtaining precise findings and information at the lowest possible expense. Calibration and validation of the developed model showed that this model had a perfect estimate of the WQI value. Due to its flexibility and impartiality, this study recommends using the proposed model to estimate and predict the WQI in the study area.Originality/valueEven though the water quality of the SAAR has been the subject of numerous studies, this is the only long-term investigation that has been done to evaluate and predict its water quality.

Applying various indices to evaluate the effects of fertilizer discharges on zooplankton biodiversity and water quality of Ismailia Canal, Egypt

One of the most useful water streams in Egypt is the Ismailia Canal. However, despite its significance, numerous factories discharge their waste into the canal, causing a drastic decrease in its water quality and fauna. In this respect, this study aims to evaluate the negative impact of fertilizer discharge on community structure, zooplankton biodiversity, and water quality in the Ismailia Canal. Four stations were selected, where the Canadian Water Quality Index and the Metal Indexwere used to determine the point source of contamination at each station. As revealed in the Canadian WQI results, Stations (3) and (4) have marginal water quality, but no metal pollution was shown in the Metal Index results of the study area. The Canonical Correspondence Analysis (CCA) was also applied. The zooplankton community structure and biodiversity were examined, where their total density recorded an average of 598,854 ind./m3. Nineteen zooplankton species—belonging to the groups: Rotifera, Cladocera, Copepoda, and Nematoda—were identified. Rotifera was predominant, representing 97.05% of the total zooplankton density. Although Station (3) had the highest diversity index, there was a special abundance of organic matter bio-indicators. That is why mandatory laws and management plans had to be enforced to mitigate the canal deterioration.

Application of the Canadian Water Quality Index (CCME-WQI) for Aquatic Life to Assess the Effect of Tharthar Water upon the Quality of the Tigris Water, Northern Baghdad City,Iraq

The present study aims to assess the effect of the Tharthar Canal as an outlet canal that feeds back from the Tharthar Lake on the quality of the Tigris water. Utilizing a Canadian Water Quality Index (CCME-WQI) for the protection of aquatic life Water samples were obtained every month from January to December of 2020. Six different sites were selected: four along the Tigris River and two on the Tharthar Canal. Seven ecological parameters were used to assess water quality depending on importance and availability: water temperature, Water Temperature, Turbidity, Dissolved Oxygen (DO), Total Dissolved Solids (TDS), pH, Nitrate (NO3-) and Phosphate ( . The study demonstrated that the water quality of the Tharthr canal ranked as a fair class, whereas that of the main river fluctuated from marginal class before the confluence area to fair class downstream of the confluence. Also, three variables, including water temperature, turbidity, and total dissolved solids, were not meeting water quality standards.

Evaluation of the water quality of a high Andean lake using different quantitative approaches

This study assessed a high Andean lake's trophic state and water quality using methodologies with eutrophication and water quality indexes. Water samples were collected at six points in the lake, with a monthly frequency, for three winter and three summer months. Dissolved oxygen, pH, phosphates, nitrates, transparency, chlorophyll-a, fecal coliforms, biological oxygen demand (BOD), temperature, and turbidity were determined at each point. The trophic state of the lake was categorized by applying the Organization for Economic Cooperation and Development (OECD) eutrophication index, Carlson's trophic state index (CTSI) and trophic index (TRIX). In addition, National Sanitation Foundation water quality index (NSF-WQI), Canadian Water Quality Index (CCME-WQI) and Oregon Water Quality Index (OWQI) were used to evaluate water quality. Results indicated that the lake had a high level of eutrophication, suggesting an excessive accumulation of nutrients in the water. CTSI and TRIX index showed that the lake was in a hyper-eutrophic state, while according to the OECD methodology, the trophic state related to phosphorus and transparency was hypereutrophic, and according to chlorophyll, it varied from mesotrophic to eutrophic. The NSF index classified the lake with average quality, the CCME index indicated fair water quality, and the OWQI classified it as very poor. Therefore, the water quality of the high andean lake assessed by eutrophication and water quality indexes presented significant differences based on physicochemical characteristics. The human influence was identified as the main cause of eutrophication, including tourism and agriculture. These results suggest that measures should be taken to reduce human activity in the area and control pollution in the lake.

Use of Epiphytic Diatoms in Cyperus Papyrus L. As Bioindicators in the Assessment of the Health of the Upper Euphrates River Between the Haditha Dam and Al-Baghdadi, Iraq

The aim of this study is to use epiphytic diatoms in Cyperus papyrus L. plant as biological indicators for estimating the water quality of the upper Euphrates River between Haditha Dam and Al-Baghdadi. Biodiversity and biological indicators for water quality estimation, along with the Canadian Water Quality Index. The study showed that the water of the upper Euphrates River is warm, light alkaline, the electrical conductivity and the total dissolved soled of water affected by agricultural land water and human activities, turbidity, total hardness and the biological oxygen demand, chloride and sodium did not exceed the permissible limits, while the values of calcium, nitrate and phosphate exceeded the permissible limits. And that the calcium values have exceeded the magnesium values, and that the water in the river is well ventilated. We have identified 130 species of epiphytic diatoms in Cyperus papyrus L. plant, including 6 species (5%) belonging to the centrales diatoms and 124 species (95%) belonging to the pennales diatoms, and the highest total number of cells of the epiphytic diatoms was recorded as 1322.3 cells x 103 / gm in site I. The values of physical and chemical factors, ecological indices, and water quality index agreed that the water of the upper Euphrates River is of moderate pollution, medium biodiversity, mesotrophic, and homogeneous in the presence of species.

Physicochemical Alteration and Water Quality Index of Ede-Onyima Lake, Okarki-Engenni, in Rivers State, Nigeria

Freshwater quality is deteriorating as a result of ongoing threats from both anthropogenic and natural sources, resulting in an overall loss of ecological integrity. To provide an easily-understandable summary of complex water quality data, water quality indices (WQIs) -the Canadian water quality index (CWQI 1.0) model -was used for two distinct purposes, to assess the portability of the water and its suitability for the protection of aquatic life. The Canadian Council of Ministers Environment's water quality index (CCME WQI) was calculated by combining three variables: scope (F1), frequency (F2), and amplitude (F3), to produce a single value between 0 (worst) and 100 (best) representing the water quality. Predominantly impacted by the F3, which resulted in a WQI score of 32. Ede Onyima lake was ranked “poor” indicating that it is unfit for human consumption and aquatic life protection. The lake was impaired by high turbidity (86 NTU), trace metals such as Fe (20.73 mg/L), Mg (8.67 mg/L), and Mn (5.92 mg/L) loads. Their remobilization during turbulent flow portends a harmful effect on the Ede Onyima's water quality, indicating the critical need for a cohesive lake watershed management system to sustain conservation purposes of the lake and sustenance lake-dependent livelihoods.

EVALUATION OF AL KABEER AL SHAMALI RIVER'S WATER SUITABILITY FOR DRINKING, BASED ON MODELING AND PSEUDOMONAS AERUGINOSA DETECTION IN SYRIA

Using river water as a source for drinking water is a big challenge. The aim of this study was to determine the fate of Pseudomonas aeruginosa "opportunistic bacteria " in Al Kabeer Al Shamali River and its correlation with drinking water quality (pH, Electrical conductivity, Turbidity, NO3-, NO2-, NH4+ and PO4-3) in three locations; lake inlet " Ghammam Bridge ", artificial (the 16th Tishreen Dam Lake, and the outlet Ain al-Bayda irrigation tunnel). during the period 2018-2019 and 2019-2020. The membrane filtration technique was used to detect Ps. Aeruginosa. Results showed significant differences (p<0.05) between sites for Ps. Aeruginosa, EC, Tur and NO3- . The highest counts for Ps. aeruginosa recorded in Ghammam Bridge water reaching 290000 cfu/100 mL ​​in Jun and correlated with NH4+ (r =0.72). Then counts decreased to 420 cfu/100 ml in May in 16 Tishreen Dam Lake water, due to stratification and environmental stresses. Ps. Aeruginosa counts were higher in lake outlet than 16th Dam Lake and reached 53000 cfu/ 100 ml in July, May due to the release from sediments. Canadian Water Quality Index CCME WQI showed that the lake inlet water is moderate class C (64). The waters of 16th Dam Lake and the outlet are of good grade II B due to sedimentation. These results provide the basis for choosing appropriate sterilization methods to reach health goals to connect this major water source to the drinking water network in Lattakia city

Impact of Land Use/Land Cover and Landscape Pattern on Water Quality in Dianchi Lake Basin, Southwest of China

The water quality of a basin is pronouncedly affected by the surrounding types of land use. Analyzing the impact of LULC and landscape patterns on water quality is critical for identifying potential drivers. To further study how LUCC affects the water quality in a typical plateau lake basin, this study investigated the impacts of land-use types on water quality in the Dianchi Lake Basin in Southwest China. We analyzed changes in land-use types and the landscape pattern of the Dianchi basin, calculated the CWQI (Canadian Water Quality Index) value based on the water quality indexes (PH, total phosphorus (TP), total nitrogen (TN), chemical oxygen demand (COD), dissolved oxygen (DO), permanganate index (CODMn), five-day biochemical ox-ygen demand (BOD5), ammonia nitrogen (NH3-N), turbitidy, and chlorophyll-a (Chla)), used the RDA (Redundancy Analysis) and SMLR (Stepwise multiple linear regression) methods, the coupling degree, coupling coordination degree, and the geographical detector model to explore the relationship between water quality and changes in the land-use type. The results show that (1) changes in the land-use types were obvious: the majority of the land, which was originally forest land, became built land in 2020 and farmland in 1990 (except for the Dianchi water). Landscape pattern indexes indicated that almost all land-use types were first scattered, then gathered from 1990 to 2020. (2) Changes in the water quality of Dianchi Lake lagged behind the changes in land-use types, and the variation trends were similar to the landscape pattern variation trends. The CWQI value decreased in a nearly linear fashion from 1990 to 1998, exhibited a slight change from 1999 to 2013, and quickly increased from 2013. (3) Land-use types demonstrated a tight correlation with the Dianchi water quality, and LPI was the most dominant factor in both Caohai Lake and Waihai Lake. (4) There were different indexes affecting the coupling coordination degrees of Caohai Lake and Waihai Lake.

Development of Canadian Water Quality Index (WQI) of Vidhyadhari, an Estuarine River in Eastern India

Surface water represents one of the most utilized sources for water distribution systems globally, despite the fact that rapid urbanization and industrialization has reduced its cleanliness. As a result, the end-user's health is seriously impacted by the dirty water. Nevertheless, it is clear that many developing nations, including India, pay little regard to or care about this crucial issue. The Vidhyadhari River has become a receiver of high organic and bacteriological load of entire Kolkata City through Basanti canal. As a result, the purpose of this investigation is to evaluate how rapid urbanization and industrialization has changed the water quality of Vidhyadhari River using Canadian Water Quality Index (WQI). We have used seasonal water quality data collected at two monitoring stations (Haroa bridge and Malancha) from 2011 to 2020 to study the water quality of Vidhyadhari River. Results of the study indicated that the annual WQI value of Haroa brigde ranged between 21.62 (very bad) and 62.89 (medium) with an average of 27.29 (bad), whereas annual WQI value of Malancha station ranged between 15.44 (very bad) and 43.09 (bad) with an average of 18.77 (very bad). In comparison to downward location, the water quality of Vidhyadhari River was somehow good at upstream i.e., Haroa brigde. According to WQI, the water quality of Vidhyadhari River fall into bad to very bad category, which indicated deterioration of river water quality. Factor analysis revealed that both stations are predominated by hardness cluster (hardness, calcium, magnesium and chloride) followed by cluster of total dissolved solids (TDS), sulphate and ammonia. Sewer, excessive human activity, industrial discharges, poor sanitation, and urban runoff outflow can be extrapolated as the main causes for the deterioration of Vidhyadhari River water quality. This study emphasized the significance of implementing measurement actions, introduction of watershed characteristics and implications for developing water management strategies.

Using Canadian Water Quality Index method to evaluate the spatio-variation of water quality and the impacts of quality parameters: a case study of Amasya's surface water (Northern Turkey).

In this study, the spatial variation of water quality in Yeşilırmak River passing through Amasya was investigated using the Canadian Water Quality Index (CWQI). For this aim, the measured 15 parameters in 3-month periods between the years 2008 and 2015 were used at 11 sample points from the Yeşilırmak River and its tributaries. The calculated CWQI scores using parameters of pH, Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), ammonia, ammonium, nitrite, nitrate, phosphate, iron, copper, zinc, potassium, sulfate, sulfite and chlorine range from 33 to 64. These scores indicate that the surface waters in the studied area are poor to marginal in quality. The effect of each parameter on the CWQI scores by excluding each parameter, one by one, considering the water quality of the Yeşilırmak River was investigated using the Hierarchical Cluster Analysis (HCA) method. It was determined that the presence and/or absence of the parameters, which caused an increase or decrease in CWQI scores, were ammonia, phosphate, COD, sulfide, iron, ammonium, nitrite, DO. On the other hand, the parameters having positive effects on CWQI are nitrate, chlorine and potassium. The HCA statistical analysis method is suitable for interpreting complex water quality datasets and understanding time/location dependent changes in water quality. HCA can be used effectively to group parameters in river water quality monitoring programs.
