Summary: In this study, a natural laterite adsorbent from Vietnam was investigated for its potential application in removing arsenic contamination from drinking water supplies. The adsorbent exhibited good adsorption capacity for arsenic and the study also developed a model to predict the adsorption performance in column experiments and filters.

Summary: This paper presents a comprehensive field testing programme in Mirabel, Quebec, which demonstrates the thermal effectiveness of a standing column well installed in a pervious layered aquifer. The study shows that advective heat transfer mechanism can have a significant contribution to the thermal response, even without bleed, in specific geological environments.

Summary: Epithelial tissues undergo changes in form and function in response to mechanical perturbations, and these changes are often accompanied by reactive forces that counteract the applied force. This oppositional behavior suggests the presence of mechanical homeostasis in epithelial tissues, which is implicated in various biological processes including embryonic morphogenesis, wound healing, and tissue maintenance.

Summary: This paper presents a method to filter systematic errors in drawdown data during the calibration of a groundwater model. By introducing a bias correction term and combining a natural head model with a drawdown model for optimization, parameters can be effectively estimated and the best conditional estimate can be obtained.

Summary: This study proposes an engineered injection and extraction (EIE) method to enhance the removal and mixing of liquid solutions in aquifers. The results show that EIE can significantly improve removal efficiency and mixing, especially under conditions of preferential channels, high permeability heterogeneity, and a mobility ratio larger than one.

Summary: Understanding groundwater flow and contamination transport requires characterizing aquifer attributes and hydraulic connectivity structures. In evaporitic aquifer systems, karst conduits and fault zones are important preferential flow channels that impact saltwater exploitation. Hydraulic connectivity can enhance inflow of less evaporated brine, improving efficiency. A study using stochastic inversion method showed successful characterization of preferential flow zones in a large evaporitic aquifer, with consistent results from different data sources.

Summary: Geological carbon sequestration is a mechanism to mitigate climate change by capturing and storing CO2 in deep geological formations. This study investigates the impact of heterogeneity and gravity factor on the dissolution efficiency of CO2 in saline formations. The results show that the migration and dissolution of CO2 are influenced by the interplay between heterogeneity and gravity, and the underestimation of dissolution efficiency is common in numerical models due to the inability to accurately represent heterogeneity.

Summary: We propose a methodology to quantify the impact of model structure and parametric uncertainty on biotransformation processes of Emerging Contaminants in subsurface water resources. The study aims to address the uncertainty and complexity of modeling bio-mediated reactions of recalcitrant compounds in soil and aquifers. We apply a suite of quantitative tools to diagnose uncertainty sources, estimate parameters, and select models, with the objective of balancing complexity and reliability.

Summary: This paper presents a reactive multi-component multi-phase flow program, MRST_CO2, implemented in Matlab Reservoir Simulation Toolbox (MRST), for simulating Geological Carbon Sequestration (GCS). The program can simulate multi-phase flow and transport of species undergoing chemical reactions and mass exchanges among gas, liquid, and solid phases. It has been tested with 1D benchmark and applied to heterogeneous 2D and 3D cases with structured or unstructured grid.

Summary: The emergence of large language models (LLMs), like ChatGPT, has attracted significant attention in academic and scientific circles. While ChatGPT holds promise for research and teaching purposes, there are also limitations and potential risks associated with its use. The article suggests that the academic community should adapt regulations and policies to harness the benefits of LLMs while mitigating their pitfalls.

Summary: In the context of in situ groundwater remediation, mixing is crucial for successful outcomes. The Engineered Injection-Extraction (EIE) method has been proposed to enhance dilution within the porous medium. However, existing studies have not considered the impact of connectivity and preferential flow-paths. This study demonstrates that EIE is effective in enhancing mixing regardless of the presence of preferential flow paths, diminishing uncertainty induced by medium heterogeneity.
