    • Chaotic Advection for Enhanced Reagent Mixing 

      Cho, Michelle Seeun (University of Waterloo, 2019-04-17)
      In situ remediation techniques commonly involve the injection of a reagent into the subsurface to create a zone in which biological and/or chemical reactions lead to mass destruction of contaminants. In these injection-driven ...
    • Dual Oxidant System for In Situ Treatment of Organic Contaminants 

      Jin, Yuyi (University of Waterloo, 2017-05-01)
      Recently, the potential catalytic properties of manganese dioxide have attracted attention as a means to activate persulfate. This focus of this research was on the potential ability of MnO2(s) solids synthesized through ...
    • Foam as a Vehicle for Nanoparticle Delivery in Unsaturated Porous Media 

      Sadeghi Ardestani, Zahra (University of Waterloo, 2019-05-23)
      Accidental releases, spills, and leaks of petroleum hydrocarbons (PHCs), such as gasoline and jet fuel, can result in subsurface contamination. PHCs that become entrapped as a residual light non-aqueous phase liquid (LNAPL) ...
    • Impact of Anaerobic Biofilm Formation on Sorption Characteristics of Powdered Activated Carbon 

      Rocha Diaz de Leon, Griselda Raquel (University of Waterloo, 2021-07-23)
      Subsurface contamination by petroleum hydrocarbons (PHCs) results from the leakage of petroleum products during extraction, processing or transport. It has been documented that activated carbon (AC) can effectively sorb ...
    • Multi-Component Mass Transfer and Chemical Oxidation 

      Shafieiyoun, Saeid (University of Waterloo, 2017-05-17)
      The remediation of soil and groundwater contaminated with multi-component non-aqueous phase liquids (NAPLs) such as coal tars from former manufactured gas plants (MGPs) is associated with a number of challenges. Due to ...
    • Nanoparticles as X-ray CT Imaging Contrast Agents in Saturated Porous Media 

      Carlos, Jacob (University of Waterloo, 2020-08-28)
      Parallels exist between medical imaging techniques, such as X-ray computed tomography (CT) or magnetic resonance imaging, and geophysical methods used to analyze the subsurface, such as ground penetrating radar, electromagnetic ...
    • Transport and Targeted Binding of Polymer-Coated Nanoparticles in Unsaturated Porous Media 

      Jaberi, Najmeh (University of Waterloo, 2021-08-25)
      The effectiveness of most in situ remedial technologies lies on successful delivery of reagents to a target treatment zone. Advances in nanoparticle (NP) materials has led to the targeted delivery concept in which the NP ...
