Summary: Groundwater discharge to rivers takes many forms, including preferential groundwater discharge points (PDPs) along riverbanks. The physical controls on the spatial distribution of PDPs along riverbanks are not well-defined. This study investigates the local riverbank sediment controls on PDP occurrence and uses drone-based and handheld thermal infrared imaging to map PDP locations along two mainstem rivers.

Summary: This study investigates the regional and local controls on the hydrological and thermal regimes of wetlands in the St. Lawrence River Valley region of northern New York State. The results show that wetland temperatures are strongly influenced by regional atmospheric forcing and local groundwater offset. Particularly in summer, wetland temperatures exhibit significant spatial variability due to differences in groundwater availability influenced by hydrogeomorphic settings.

Summary: Human activities in large cities can lead to pollution caused by micropollutants such as pesticides in water bodies, which pose serious threats to the environment and human health. A study in Beijing investigated the pollution levels of pesticides in groundwater and the Wenyu River, as well as their fates in sewage treatment plants and a hospital. The study found high detection frequencies for atrazine and metalaxyl, with low removal efficiencies for some pesticides in the treatment plants. The risk quotient values show that the pesticides in groundwater do not pose potential health risks to humans at current concentrations.

Summary: In many nations and locations, the presence of pharmaceuticals in groundwater and surface waters is a growing concern due to their potential impact on aquatic ecosystems and public health. This review summarizes the research evidence regarding the occurrence, impact, and fate of pharmaceuticals in different water bodies. Various analytical techniques, such as LC-MS, HPLC, UPLC-MS/MS, and GC-MS, have been used to detect and analyze pharmaceuticals in water bodies, with LC-MS being the most commonly used instrument. Sulfamethoxazole, an antibiotic, was found to be the most frequently detected drug in wastewater, while antibiotics, in general, were the most reported pharmaceutical group.

Summary: This review examines the occurrence of emerging organic contaminants and endocrine disruptors in wastewater, surface water, and groundwater in Mexico. The study found that the types and concentrations of these contaminants varied in different samples and locations. While raw wastewater had the highest number of detected compounds, surface waters also showed concentrations of some compounds exceeding international guidelines. Groundwater was primarily affected by the irrigation of croplands with raw wastewater. However, soils and aquifers were found to have a capacity to attenuate the presence of contaminants from wastewater. Despite water pollution being a major environmental concern in Mexico, there is a lack of studies on the occurrence of emerging organic contaminants in Mexican waters.

Summary: This study investigates the potential link between porewater chemistry in a thick clay-rich sequence and groundwater quality in the North China Plain. The analysis found that the higher concentrations of fluoride derived from the aqueous extraction method indicate a high susceptibility to release during changes to the ambient geochemical environment. The data supports the hypothesis that the release of ions from confined aquifers is driving degradation of groundwater quality in the NCP.

Summary: Spatial variability in flow characteristics in discharge zones in five different catchments in Sweden was investigated. Steady-state numerical models and analytical models were used to estimate the deep groundwater flow and hyporheic exchange flow velocities. Regression analysis was performed to explain the variability based on catchment characteristics. The study found that hyporheic exchange flow had a significant potential to accelerate deep groundwater flow velocity and reduce discharge areas.

Summary: This study reviewed publications using HCES data to estimate household dietary nutrient supply and found that HCES data are increasingly used to assess diets across populations. However, nutrient intakes were generally overestimated using HCES data, with significant discrepancies compared to individual dietary assessment methods. Sub-group analyses mainly focused on socio-economic and geographical variations in household dietary nutrient supply. Further research is needed to guide the use and interpretation of dietary assessments based on HCES data.

Summary: The concentrations of particulate organic carbon (POC) and particulate organic nitrogen (PON) were evaluated in 13 British estuaries, and their sources were assessed using stable carbon and nitrogen isotopes. The results showed a high variability in POC and PON concentrations within the estuaries, indicating inputs and losses of organic material. The land cover of the catchment area appeared to influence the contribution of POC to the total organic carbon flux from the estuary to coastal waters.

Summary: The World Health Organization promotes the use of Water Safety Plans (WSPs) as the most effective way to manage drinking-water supplies. However, WSPs are not widely adopted in small drinking-water supplies in Sub Saharan Africa, including Rwanda. This research aims to identify good practices and gaps for the implementation of WSPs in small drinking-water supplies in Rwanda. Through interviews with key stakeholders, it was found that although there is low awareness and usage of WSPs, certain activities aligned with the WSP methodology are already being carried out. However, greater focus on community engagement, risk review, and data management is needed to fully align with the WSP approach.

Summary: This study aimed to assess the association between serum micronutrients and non-nutritional factors with the risk of anaemia among the Ethiopian population. The findings revealed that younger age, household head illiteracy, and low serum concentrations of ferritin, cobalt, copper, and folate were associated with anaemia. Serum selenium had an indirect effect on haemoglobin through zinc. The study suggests the need for a multi-sectorial intervention to address anaemia based on demographic groups.
