Abstract: Reliability of a “preassumed” optimal remediation design using a pump and treat method is evaluated. A “true” hydraulic conductivity field with a certain spatial correlation is supposed. Hydraulic conductivity values are ...

Abstract: The objective of this study was to investigate, through laboratory and numerical investigations, the effectiveness of a pulsed air sparging system for remediation of groundwater contaminated with trichloroethylene (TCE) ...

Abstract: A framed-tube system with multiple internal tubes is analyzed using an orthotropic box beam analogy approach in which each tube is individually modeled by a box beam that accounts for the flexural and shear deformations ...

Abstract: This study proposes a numerical model for gas- and water-phase solute transport describing the change in leachate quality and gas production by microbial activities in a sanitary landfill. The proposed model includes gas ...

Abstract: Water tightness is an essential factor for the operation of underground highly pressurized gas storage caverns. To secure this tightness, the groundwater pressure must be greater than the gas pressure, and the groundwater ...

Abstract: Soil and ground water in a shallow aquifer were contaminated by petroleum hydrocarbons, mostly comprised of toluene. The degrees of soil and ground-water contamination were closely correlated. The vertical profile of soil ...

Abstract: This study compares various leachate management scenarios using a biologically reactive transport model, which is proposed in this study. The proposed model can be used to predict the contribution of biodegradation to ...
