RISThree-Dimensional Laboratory Experiments on Fate and Transport of LNAPL under Varying Groundwater Flow Conditions
Publisher: ASCE
Abstract: Variations in groundwater flow regimes due to direct draining/pumping and surrounding climatic variabilities may significantly affect the spatial and temporal distribution of hydrocarbon compounds in the subsurface. The ...
Development of nZVI-Pumice/Zeolite Composites for Effective Removal of Arsenic (III) from Aqueous Solution
Publisher: ASCE
Abstract: Nano zero valent iron (nZVI) composites were developed with iron loading ratios of 10% and 20% (w/w) using base materials, pumice, and zeolite. The four composites (PnZVI 10, PnZVI 20, ZnZVI 10, and ZnZVI 20) developed ...
Performance Evaluation of Aquifer Storage and Recovery (ASR) System in Saline Groundwater Regions: Impact of Operational Factors and Well Design
Publisher: ASCE
Abstract: Application of aquifer storage and recovery (ASR) is difficult in highly saline groundwater regions because the recharged freshwater mixes with saline groundwater and makes a thin layer below the capillary fringe. The ...
Role of Hydrogeological Factors on Aquifer Storage and Recovery Performance in Saline Groundwater Regions
Publisher: ASCE
Abstract: Aquifer storage and recovery (ASR) is a potential solution to growing global freshwater insecurity. However, the performance of ASR in saline regions depends on regional hydrogeology and groundwater salinity level. ...
Transient Water Flow and Nitrate Movement Simulation in Partially Saturated Zone
Publisher: American Society of Civil Engineers
Abstract: Water flow through vadose zone is important for soil ecology and for groundwater development. A thorough knowledge of water flow and solute transport through unsaturated zone is also needed for sustainable irrigation ...
Enhanced Performance of Aquifer Storage and Recovery System in Unconfined Saline Aquifer for Different Operational Factors: A Multidimensional Laboratory and Modeling Study
Publisher: ASCE
Abstract: Aquifer storage and recovery (ASR) in saline unconfined aquifers is challenging as the injected freshwater makes a thin layer above the groundwater table. For this reason, the efficiency of ASR in unconfined saline aquifers ...
In Situ Treatment of Arsenic-Contaminated Groundwater via Extraction Well–Integrated Permeable Reactive Barriers
Publisher: ASCE
Abstract: A pumice–maghemite (P-maghemite) composite was developed using the chemical coprecipitation method with a 20% iron loading ratio by weight. The characterization of the composite using SEM and XRD indicated the effective ...
Modeling of Nitrate Transport in the Vadose Zone by Considering the Mobile–Immobile Approach Using a Sand Tank Experiment
Publisher: ASCE
Abstract: Precise process-based modeling of nonequilibrium water flow and solute transport continues to pose a significant challenge in vadose zone hydrogeology. Nonequilibrium water flow and solute transport in the vadose zone bring ...
Effects of Cocontamination by Toluene on Cr(VI) Adsorption by P-nZVI in a Soil–Water System: A Fixed-Bed Column Study
Publisher: ASCE
Abstract: Soil–water cocontamination with heavy metals and nonaqueous phase liquids (NAPLs) raises widespread concerns. Coexisting NAPL pollutants like toluene can antagonize the chemical processes employed for removing target heavy ...
Migration of CO2 through Carbonate Cores: Effect of Salinity, Pressure, and Cyclic Brine-CO2 Injection
Publisher: ASCE
Abstract: Geo-sequestration of carbon dioxide (CO2) in saline formations is one of the feasible options for reducing the concentration of carbon in the atmosphere. This process involves the capturing of CO2 from emission sources ...
