Summary: The study investigates the recovery efficiency of aquifer storage systems with radial flow fields for heterogeneous aquifers, with a focus on the impact of macrodispersion. It is found that recovery efficiency is significantly influenced by macrodispersion, while recovery efficiency is positively correlated with injection-extraction rate and duration when local dispersion dominates. As macrodispersion becomes increasingly dominant with scale, the recovery efficiency may exhibit nonmonotonic behavior.

Summary: "The study shows that the recovery efficiency increases with increasing injection-extraction flow rates and decreasing dispersion. In three-dimensional flow fields, the recovery may vary non-monotonically with cycle period due to competition between diffusion and mechanical dispersion."

Summary: This paper investigates the feasibility of using ASR techniques for freshwater storage and recovery in saline confined aquifers. The study examines the impact of operational factors on the efficiency of freshwater recovery. Experimental results suggest that ambient groundwater salinity, injection volume, storage duration, and the number of cycles all significantly influence the efficiency of ASR systems.

Summary: Aquifer storage and recovery (ASR) is an important component of the Comprehensive Everglades Restoration Plan. Using high permeability limestones in south Florida, the Kissimmee River ASR system successfully completed four cycles of recharge-storage-recovery, demonstrating the feasibility of ASR. However, improvements are needed in the pretreatment system to meet regulatory compliance.

Summary: This study developed a variable-density groundwater flow modeling framework to evaluate the performance of aquifer storage and recovery (ASR) in highly saline groundwater regions. The results showed that operational factors and well design have a significant impact on the recovery efficiency of ASR, and adjusting these factors can improve the overall performance.

Summary: The evolution of denitrification kinetics in an ASTR system was investigated, showing an increase in first-order denitrification rate constants before and during ASTR operation, possibly due to microbial adaptation and bioaugmentation. Push-pull tests revealed negligible denitrification rate constants initially, with an increase after a lag-phase. During ASTR operation, denitrification rate constants increased over time, but were lower during storage periods. Denitrification coupled to pyrite oxidation was observed at all depths.

Summary: Groundwater depletion and overextraction in India has become a major concern. Aquifer storage and recovery (ASR) is a popular intervention for recharging and recovering water, but selecting suitable locations and aquifers for recharge is challenging. This study classified site selection criteria for ASR installations in different types of aquifers in North India using scientific and social indicators. The results showed that socio-economic parameters should be considered in the decision-making process. Seven potential ASR sites were selected based on these indicators in Bihar, India.

Summary: This study investigates the process of CO2 dissolution in deep saline aquifers through numerical simulations, and highlights the importance of considering hydrodynamic dispersion and multispecies geochemical reactions. Results indicate that accounting for hydrodynamic dispersion can increase the CO2 dissolution flux and decrease the convection onset time, while geochemical reactions can enhance long-term efficiency but reduce total sequestered carbon during the diffusion-dominated period. The study emphasizes the significance of realistic geochemical representation and the spatial and temporal dependence of reactions for detailed simulation of the CO2 storage process.

Summary: The study developed a new numerical model considering wellbore storage, and found that the uniformly distributed flux boundary condition may lead to significant errors in modeling reactive transport, which become negligible at the late stage of the extraction phase.

Summary: This study aims to optimize the ASR technique in unconfined saline aquifers to maximize its recovery efficiency through sand tank experiments and numerical modeling. The results showed that shallow injection depths, higher injection/extraction rates, and smaller storage durations lead to higher freshwater recovery.

Summary: Y Managed Aquifer Recharge (MAR) is a key strategy to increase freshwater resources in regions facing water scarcity. This study explored the potential of injecting lower quality water into aquifers and utilizing biogeochemical reactions to improve water quality. The research found that supplying treated wastewater to mimic MAR can enhance nutrient dynamics in aquifers.

Summary: This study found through experiments that periodic injections of freshwater and seawater can significantly alter the coastal groundwater chemistry, mainly due to sediment-water interactions. In addition to seawater-freshwater mixing, geochemical processes such as ion-exchange, mineral precipitation/dissolution, and adsorption/desorption of elements have been identified as factors controlling the pore water chemistry.

Summary: In this study, a multiwell ASR system was simulated in a synthetic aquifer, which showed that higher hydraulic conductivity and longitudinal dispersivity reduce system efficiency while increasing recharge volume improves recovery efficiency but decreases energy efficiency. Operational factors have a greater impact on multiwell systems, and fewer wells can yield higher volume of potable water and better output in terms of energy consumption.

Summary: This study describes the variations in concentrations of 12 chemical elements in groundwater relative to salinity levels in Southern Quebec (Canada) groundwater systems. It develops an empirical predictive model for evaluating groundwater chemical composition relative to salinity levels based on the data. The study shows that major elements dominate at lower salinity levels, while chloride becomes dominant at higher salinity levels.

Summary: This study focuses on investigating the combined effects of seawater intrusion and nitrate contamination in a Mediterranean coastal agricultural area. The results show that seawater intrusion is mainly influenced by the Mediterranean Sea and river mouth, while nitrate contamination primarily comes from sewage and manure sources. The study emphasizes the dual negative impact of seawater intrusion and nitrate contamination on water quality.
