Summary: Groundwater samples were collected from the phreatic aquifer and first confined water layer in the Yancheng area of the Huaihe River during the summer of 2016. The study evaluated the suitability of the groundwater for drinking and irrigation purposes using the water quality index. The results showed a lack of high-quality groundwater for drinking and limited suitability for irrigation due to the presence of alkali metals and poor water quality distribution.

Summary: Water is crucial for human survival, but its quality can decline due to pollution and contamination caused by the growing population and industrial facilities. The Water Quality Index is widely used to evaluate surface water quality, and this study explores various models that can help assess water quality in different areas. The level of contamination in water affects its overall quality, and pollution indices are useful tools for measuring pollution levels.

Summary: In this review, the importance of a robust framework for drinking water quality monitoring, assessment, and management is discussed. It provides a global overview of drinking water quality, highlighting the challenges of the water supply system and discussing regulatory frameworks and risk analysis tools. The paper also summarizes water reports released by government and non-governmental organizations in Pakistan, focusing on health-based targets, preventive risk management strategies, environmental impact assessment, and independent surveillance. The review emphasizes the role of agencies and their policies in water quality management and monitoring, and highlights the dangerous impacts of unsafe water on health and the economy of a country. The study concludes that improved access to safe drinking water can have tangible improvements in a country's socioeconomic status.

Summary: Water quality monitoring programs often fail to address multiple aspects simultaneously. This study develops a versatile and systematic framework for monitoring program development and applies it to the Quabbin watershed in Massachusetts, USA. The results show that decreasing sampling frequency often reduces the ability to detect significant trends. No sampling reduction method consistently resulted in a lower absolute error.

Summary: The 2000 European Union Water Framework Directive aims to protect bodies of water and reduce the level of purification treatment required for drinking water. However, it does not provide a specific method for evaluation or quantification of this treatment level. A novel water quality index (WQI) is proposed in this study, which compares contaminant concentrations in source water to drinking water guidelines and accounts for treatment processes' resilience. It is also adaptable to varying sampling frequencies. The findings suggest that the required purification treatment levels have not decreased since the implementation of the WFD.

Summary: Water quality in Pakistan is a major problem due to population growth, industrial units, and agricultural activities. This study aims to comprehensively evaluate water quality monitoring and assessment in Pakistan. The research examines the different water sources and methods used for monitoring and assessing water quality, highlighting high concentrations of arsenic, fluoride, and fecal coliforms in certain regions. Natural factors and the impact of water pollution on public health are also discussed. The paper emphasizes the need for innovative strategies, research investment, and improvements in monitoring frameworks to ensure clean and safe water for all stakeholders involved.

Summary: Groundwater quality monitoring often relies on sporadic and slow manual sampling and laboratory analyses, which may result in undetected water quality deficiencies. In Finland, enhanced monitoring of untreated groundwater quality using real-time online monitoring, isotopic analysis, and microbial community analysis revealed indications of surface water intrusion and faecal contamination. The findings demonstrated the usefulness of supplementary methods and suggested their wider implementation to enhance groundwater quality monitoring.

Summary: This study evaluated the suitability of data-driven models of different complexity for predicting E. coli concentrations in a river in Gothenburg, Sweden. Models with multiple predictors outperformed univariate models, with Random Forest and TPOT showing higher performance but a tendency of overfitting. Water temperature, microbial concentrations upstream and at the water intake, and precipitation upstream were identified as important predictors.

Summary: This study assessed the quality of drinking water in Al-Hassa and evaluated the performance of water purification plants using the Water Quality Index. The purified water met the standards for drinking water, while untreated groundwater samples were of poor quality. Further purification techniques are necessary for the groundwater in the area to be suitable for drinking purposes.

Summary: Access to drinking water is a human right, and this research evaluated the Safe Drinking Water Access Index (SDWA) and inequalities in access in all Brazilian municipalities. The study revealed low SDWA rates and high inequality index values in the north and northeast regions, particularly in rural areas with low GDP per capita. The adapted Gini Index highlighted significant inequalities in safe drinking water access.

Summary: This study systematically reviewed the progress of the drinking water quality index (DWQI) and assessed the methods used in each step of DWQI development. The results showed variations in the selection and weighting of physicochemical parameters, as well as the use of different methods to overcome subjectivity. Two distinct approaches, fuzzy logic and CCME-WQI, were discussed. The study also highlighted the need for clear principles, detailed method disclosure, and validation of the developed index in future research.

Summary: This study focuses on the water quality of the Kor River in southwest Iran, finding that industrial areas are more polluted than upstream areas, primarily influenced by parameters such as BOD, COD, NO3-, and coliforms. Linear regression results indicate that BOD is the best parameter for predicting coliforms, while Cr, PO43-, Hg, and Zn levels are best for predicting Water Quality Index values.

Summary: By dividing Baluchistan into different zones based on geography, water availability, and climate, the study explores the water profile of the region. The results show an increasing trend in the concentration of various ions from the highlands to the desert and coastal zones. While some zones meet the drinking water quality guidelines, others exceed the recommended parameters. The study suggests the implementation of control measures and targeted water purification programs to protect public health and ensure the sustainability of water resources.
