Summary: The study establishes a hydrodynamic and water quality model of Dongzhang reservoir and analyzes the sensitivities to sudden water pollution events. It finds that dry years are the most unfavorable operating years, and wind field is the main driving force for flow field. Water transfer projects significantly change the main flow route of the reservoir in dry seasons and result in an increase in total phosphorus concentration in the short term. The study provides guidance for pollution control, ecological restoration, and management.

Summary: Urban stream syndrome refers to the physical, chemical, and biological transformations of stream systems in an urban environment. Most studies focus on land cover as a predictor, rather than land use. This study found consistent relationships between different land use variables and water quality indicators.

Summary: This study evaluated the impacts of wastewater treatment plants with different classifications of tertiary treatment on nutrient dynamics in the River Wensum catchment, UK. The majority of nutrients were found in bio-available forms, with phosphorus mainly of agricultural origin. Phosphorus-stripping facilities did not reduce total P concentrations downstream of WWTPs, indicating their insufficiency in overcoming population pressures and ensuring river reaches good hydrochemical status.

Summary: Global warming has caused sea levels to rise, leading to seawater encroachment in low-lying coastal areas such as Kuala Kedah, Malaysia. This study assessed the impact of seawater intrusion on water quality and the health of paddy crops using spatial technology approaches and hydrodynamic modeling. The results showed that salinity concentration varied during different seasons and tidal events and had a significant effect on the vegetation index and crop yield. By considering mitigation factors, the impact of coastal flooding and seawater intrusion could be reduced by up to 20%. These findings are important for understanding and mitigating the effects of global warming on coastal agriculture.

Summary: This study reveals the impact of large-scale floating photovoltaic (FPV) power stations on the aquatic environment through long-term monitoring and data analysis. The results show that FPV reduces the concentration of dissolved oxygen, while increasing the concentration of chlorophyll a, nitrate nitrogen, and total phosphorus. FPV also has a cooling effect during the daytime and a thermal insulation effect at night on the water body.

Summary: This study evaluates the impact of slash-pile burning on the quality of runoff waters through two experimental burns. The results show that burning has a significant effect on water quality parameters, while runoff and erosion are more dependent on precipitation patterns.

Summary: Anthropogenic waste streams can be a significant source of antibiotic resistant microbes in the environment, posing a potential risk to public health. A study conducted at a popular swimming beach in Australia found that following significant rainfall, levels of faecal indicator bacteria and antibiotic resistance genes (ARGs) increased significantly, indicating an elevated human health risk. The study also identified stormwater drains as the main points of ARG input, and observed positive correlations between ARGs and certain stormwater drain indicator taxa, including human pathogens.

Summary: Off-flavours in fish products from recirculating aquaculture systems, caused by geosmin and 2-MIB produced by actinobacteria, myxobacteria, and cyanobacteria, are a significant issue impacting the fish farming industry. These off-flavours deteriorate the quality of fish and require additional costs for removal.

Summary: Recent evidence suggests that coronaviruses can survive in low-temperature environments and groundwater for over a week, with genetic materials of the virus found in raw municipal wastewater, raising concerns about potential viral spread. A lack of information on the presence and spread of COVID-19 in the environment may lead to decisions based on local concerns and hinder the integration of SARS-CoV-2 into the global water cycle. Additional research is needed to comprehensively understand the occurrence and outbreak of COVID-19 in aquatic environments and water resources.

Summary: A two-dimensional coupled hydrodynamic and water quality model was used to assess the improvement of water quality in Lake Hou in Wuhan. The study compared the amount of pollutants in the lake before and after pollution interception and control. The results showed that the water quality improved with increased recharge flow.

Summary: Due to their long half-life, PCBs can easily contaminate coastal areas and travel to remote regions. The distribution patterns of PCBs are determined by the physical and biogeochemical features of each coastal area. Processes like atmospheric influx, ad/absorption, photolysis, and biological degradation vary for different PCB congeners. We developed a new chemical model to analyze the fate of individual congeners.

Summary: The EU Water Framework Directive (WFD) is considered a milestone in environmental legislation, but many European water bodies still fail to meet its ambitious goals. This study focuses on the impact of the WFD on the River Wensum in eastern England. By analyzing water quality data from 2000 to 2022, it reveals improvements in wastewater treatment but a deterioration in agricultural pollution indicators. Concentration spikes of organic chemical contaminants and changes in discharge increase the risk of riverine pollution. Despite achieving good or high water quality status for some indicators, compliance with WFD goals for phosphorus and nitrogen is low and projected to persist due to legacy stores and climate change effects.

Summary: The rapid transmission of the novel coronavirus has posed severe challenges worldwide, but has also led to improvements in air quality. The virus has been detected in air and sewage samples in various global studies. Water treatment companies face difficulties due to pressures such as potential aerosolization, PPE shortages, and changed usage patterns.
