Summary: Growing demands on water supply have led to overexploitation of aquifers, resulting in a decline in groundwater quality. Managed aquifer recharge (MAR) has been proposed as a solution, but its effectiveness on improving regional groundwater quality caused by non-point sources is uncertain. This study used geostatistical and numerical models to investigate the impacts of different MAR strategies on groundwater quality, and found that strategic, high-intensity recharge operations in geologically favorable subregions can significantly improve groundwater quality in terms of salinity. However, it would take decades to alleviate groundwater quality concerns in the studied region.

Summary: This study developed a flow and multi-component reactive transport model to evaluate the impact of managed aquifer recharge (MAR) on groundwater quality and geochemical processes. The results showed that groundwater geochemistry can be significantly altered during MAR, with nitrate dilution being the main process responsible for observed changes in groundwater quality. Regular monitoring and reactive transport modeling analysis are recommended to minimize the adverse impact of MAR operations on groundwater quality.

Summary: Given the decline in groundwater levels in California's Central Valley, it is important to implement managed aquifer recharge to supplement groundwater systems. This study assessed the use of airborne electromagnetic (AEM) data to locate incised valley fill (IVF) deposits, which can serve as optimal sites for recharge. The AEM data successfully identified IVF deposits in the Kings River alluvial fan, demonstrating the potential for this method to rapidly locate and utilize these valuable natural infrastructures for groundwater recharge.

Summary: This study assesses Managed Aquifer Recharge (MAR) projects proposed by groundwater sustainability agencies in California and examines the types of projects proposed, stated aims, potential barriers to implementation, and ability to achieve goals. Recharge basins are the most common approach, with hopes of improving water table levels, reducing subsidence, and improving water quality being primary goals. Concerns include lack of water availability, legal challenges, and minimal consideration of funding and land needs. Broader considerations for ensuring MAR as an effective water management tool are discussed in conclusion.

Summary: Studies have shown that applying mathematical integration to line-sink solutions, like the one developed by Hantush in the 1960s, can be directly used to derive analytical solutions for a variety of hydrogeological settings. This approach allows for the consideration of different factors such as the presence of pumping wells, aquifer boundaries, and recharge areas, providing a unique solution that can be applied to managed aquifer recharge designs.

Summary: Water scarcity is a major challenge for economic and social development in arid and semi-arid regions. Managed aquifer recharge (MAR), including techniques like soil aquifer treatment (SAT) and agricultural MAR (Ag-MAR), is crucial for sustainable water management. The integration of agricultural fields for groundwater recharge through Ag-SAT could provide alternative infiltration sites and nutrient sources, presenting both advantages and challenges for water sustainability.

Summary: The majority of freshwater in the aquifers of the Ningbo Basin has been replaced or mixed with seawater due to tectonic activity. Only one freshwater lens remains in the central area of the basin. Research on the deep confined freshwater lens in the basin is lacking and evidence is insufficient. Data from monitoring wells indicate ongoing groundwater exploitation. Tectonic stress field evolution and fault analysis suggest that concealed faults likely act as conduits for water. Tests and analyses of hydrochemical ions and isotopes confirm the hypothesis that the deep confined aquifers are recharged with modern water from the bottom through concealed faults.

Further modeling is needed due to nonuniqueness of the drawdown log-derivative signal.

Summary: Due to technical and administrative constraints, dense data acquisition for 3D high-resolution aquifer mapping through heliborne transient electromagnetic (HTEM) survey is not possible. Therefore, ground geophysical surveys are used in the no-fly area to collect sub-surface information. By integrating both types of data, the same spatial density as the flown area is achieved in the no-fly area, enabling the completion of 3D aquifer mapping at high spatial resolution for the entire area.

Summary: Groundwater accounts for a significant portion of domestic water use and irrigation in India, and with rapid urbanization and population growth, its status is being greatly affected. This study focused on the groundwater trends and the impact of land use change in Mumbai city. The results showed an overall increase in groundwater depths, especially during the dry season. The northern interior of the city experienced steeper decline rates, likely due to increased urban impervious surfaces. Some stations in the southern part of Mumbai showed decreasing groundwater depths during the wet season, possibly due to saltwater intrusion. Exploiting deeper aquifers and implementing engineered recharge are sustainable solutions. These findings are relevant for other urban areas experiencing similar rates of urbanization and population increase in the Global South.

Summary: To analyze the effect of a new gelling agent for hydraulic fracturing, fluid samples from different stages of the operation were collected from a well in Argentina. The samples were analyzed over a period of two years, showing an increase in salinity due to mixing with formation water and a decrease in concentration of trace elements and heavy metals, possibly due to delayed precipitation of barite. This finding suggests a potential option for mitigation and remediation of wastewaters from hydraulic fracturing.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.

The authors found that the spectral characteristics of dissolved organic matter (DOM) in surface water and sediment porewater could be used to predict DON variations in riverbed sediments. Random forest and extreme gradient boosting machine learning methods were employed to provide accurate predictions of DON content and properties at different depths.
