Passive Site Remediation for Mitigation of Liquefaction Risk
Passive site remediation is a new concept proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction. It is based on the concept of slow injection of stabilizing materials at the edge of a site and delivery of the stabilizer to the target location …

Sustainable site remediation : a life cycle assessment approach
Remediation of contaminated areas is often a resource-intensive activity that itself can create environmental burdens. Life cycle assessment (LCA) was used as a tool to examine the environmental impacts associated with remediation activities. A hypothetical contaminated site with five remediation …

Where have all the brownfields gone? : lessons for Chicago 15 years in
… challenges. Using data from the Illinois Site Remediation Program and other Chicago geospatial data, this thesis shows that the results of an incomplete Initiative were mixed, specifically the geographic distribution of site remediation and the success of publicly initiated projects. The …

Experimental and theoretical modeling of DNAPL transport in vertical fractured media
… and presence of DNAPLs at hazardous waste sites is likely to be a significant limiting factor in the site remediation process. This is especially true for the remediation of complex subsurface formations, such as fractured bedrock. This work has developed a new model describing DNAPL …

Polycyclic Aromatic Hydrocarbons and Redox Parameters in a Creosote-Contaminated Aquifer
… program to remediate a former wood-preserving site that was contaminated with creosote. Twenty-five multi-level samplers (MLSs) were installed on-site and groundwater samples were collected and tested regularly between March 1998 and July 2000. Nearly one-thousand hybrid poplar trees were …

Impact of metallic nanoparticles on anaerobic digestion
… zero valent iron (NZVI) has been proposed for site remediation and industrial wastewater treatment. In batch anaerobic digestion systems, AgNPs at the concentration of 40 mg/L did not inhibit methane production, as more than 90% of AgNPs were removed from the liquid to the associated sludge …

THE MOBILITY OF ENGINEERED MULTI-WALLED CARBON NANOTUBES IN POROUS MEDIA
… environment possibly as reactants for insitu site remediation or as leachate from landfill sites. Therefore, understanding the mobility of engineered nanomaterials in porous media is very important. Engineered multi-walled carbon nanotubes (MWCNTs) are an important class of nanomaterials from …

A Self-Potential for Monitoring Self-Sustaining Treatment for Active Remediation (STAR)
Self-sustaining Treatment for Active Remediation (STAR) is a novel soil remediation approach for Non-Aqueous Phase liquids (NAPLs) embedded in a porous medium. STAR is based on liquid smoldering combustion which destroys NAPLs while simultaneously generating heat due to the exothermic oxidation …

Flow problems in air venting and air sparging
… (SVE) and Air Sparging have been used for site remediation for about ten years, but most of the past designs are based on experiences and numerical models. Understanding toward the physical problems is far from complete, and some simplified assumptions used in those models may not be true. …

Analytical and Numerical Modelling of Thermal Conductive Heating in Fractured Rock
… (TCH) systems for the purpose of contaminated site remediation. Modelling was conducted in a fractured bedrock environment containing a system of parallel, equally-spaced horizontal fractures. A semi-analytical solution to the two-dimensional heat conduction equation was developed and used to …

Remediation and reuse of a former manufactured gas plant site in Champaign, IL
… associated with manufactured gas plant sites by using in situ remediation. Another aim was to speculate an adaptive reuse of the site through revelatory design such that it unfolds the history of manufactured gas plants as they existed in 1800s to mid 1900s and also to educate the public …

Sustainable infrastructure technologies: impact and policy
… Program. Unlike prior literature, I value site redevelopment separately from cleanup, assess whether green redevelopment adds value, and examine time to capitalization. Using a property level fixed effects model and controlling for time-varying shocks, I find that the program has added 4% …

Nanocellulose-based materials for sustainable soil remediation and water purification
… of the these materials in sustainable soil remediation and water purification. In the first part, the utilization of CNC nanofluid as an eco-friendly agent for the remediation of phenanthrene (PHE) contaminated soil is proposed. This marks the first exploration of CNC nanofluid’s …

Environmental consequences associated with ash-stabilisation of organic sludges from the synthol process
… of new innovative technologies aimed at site remediation and hazardous waste treatment. Solidification/Stabilisation (S/S) is one of such technologies and it has emerged as an environmentally acceptable treatment option for hazardous waste. Initially applied to inorganic wastes, S/S is …

Investigation of temperature effects on subsurface attenuation of nitroaromatic compounds
… contaminants were degrading under natural site conditions. Recent research at Colorado State University has shown that maintaining soil temperatures ~5°C above natural site conditions substantially increases rates of anaerobic petroleum hydrocarbon degradation. The overarching goal of this …

Time-based media in landscape interpretation: Route 66 at McCook Quarry (Chicago)
… media, is used not only to analyze the site, but also interpret the site. Site analysis was extended to include factors of time, besides those of the space, in order to exhibit the site's connections with other historical and geological wonders along Route 66, and connections with other …
