“…( Impervious surface is increased by urbanization and infrastructure development, which results in more runoff and erosion that affect surface water quality (Parween et al, 2022;Uddin et al, 2022b). Waterborne diseases are caused by improper waste disposal, such as untreated wastewater discharge (Bej et al, 2023;Fida et al, 2023). Therefore, the identi cation of areas of surface water pollution, the analysis of the sources of pollution and the treatment of such pollution are of paramount importance.…”

Maintaining good surface water quality is essential to protecting ecosystems and human health, and different targeted measures for different polluted areas are an effective way to maintain good water quality. This paper takes Henan as an example to study the spatial dependence of surface water quality and explore its spatial clustering pattern, and find out the main driving factors affecting the water quality and analyze the sources of heavily polluted areas by random forest. The results indicate that the spatial pollution pattern of surface water quality in Henan Province can be roughly categorized as insignificant pollution in the northern part, heavy pollution in the central part, and light pollution in the southern part. The heavily polluted areas are mainly located in Zhengzhou, Luoyang and Kaifeng cities. The main indicators affecting water quality in heavily polluted areas are NH3-N, CODMn and TP. The main causes of the deterioration in the region are urban sewage and industrial wastewater discharges. The results not only provide a scientific basis for the systematic management of surface water quality pollution in Henan Province, but also provide a new method for regional water pollution management.

“…When water quality is compromised in terms of clarity, appearance, or flavor, it might be considered unsatisfactory for consumers. Physical contamination also poses a potential health hazard, as numerous microorganisms are frequently linked with solid particles in water, thus elevating the likelihood of survival and dissemination of microbiological impurities [ 5 ].…”

Water is essential for daily activities and maintaining human well-being. However, in many less-developed countries, including Ethiopia, the lack of a well-developed wastewater treatment system leads to contaminated surface water. This poses significant risks to human health. To address this problem, wastewater can be treated using locally available materials such as wood ash and cement as chemical coagulants. The objective of this study was to treat wastewater using these materials. The study involved analyzing a 20-liter sample of wastewater from the Awetu River in Jimma City, Ethiopia. The materials used for the treatment included wood ash, cement, and lemon. Various doses of cement and wood ash were prepared and added to the wastewater. The results showed that 5 g was the optimum dosage for effectively treating the wastewater. The treated water at the optimum dosage exhibited significant improvements in turbidity, total dissolved solids, conductivity, and color, meeting drinking water criteria. Overall, the study concludes that locally available materials such as wood ash and cement can be successfully utilized as chemical coagulants for wastewater treatment. This approach offers a viable solution for improving water quality and reducing the risk of waterborne diseases.

Cerium vanadate/Bentonite (CeVO4/bt) nanocomposite with different composition percentages was synthesized through a simple one-step hydrothermal method at 180 ℃ then photocatalytic activity was evaluated by decolorizing methylene blue (MB) in an aqueous solution under light exposure. The structural and optical properties of the synthesized composites were determined by XRD, FT-IR, DRS, FESEM, EDS, and BET measurements. XRD and EDS results confirmed the successful synthesis of CeVO4. The calculated band gap energy for modified cerium vanadate/bentonite (CeVO4/mbt) was the lowest among all, indicating its more appropriateness for photocatalytic removal of MB dye. nanoparticles were well distributed on bentonite. Due to the synergistic effects, the MB removal efficiency (for just 0.1 g) of CeVO4/mbt nanocomposite was significantly increased (99% in 15 min) compared with neat bentonite, CeVO4, and CeVO4/bt samples. The mineralization degree of MB dye was also studied which obtained 61% for CeVO4/mbt sample. The mentioned nanocomposite followed the first order kinetics and constant speed equal to 0.957 min-1 and showed acceptable stability in five consecutive cycles. This research presents a simple approach to creating novel, very efficient modified nanocomposites for use in photocatalysis applications.
