Anaerobic Biodegradation of Petroleum Hydrocarbons in Powdered Activated Carbon Groundwater Systems: A Modelling Investigation
(University of Waterloo, 2022-09-19)Subsurface contamination by petroleum hydrocarbons (PHCs) is a widespread issue resulting from oil and gas production, distribution, and use. As a result of improved injection methods and particulate materials, injected ... -
Chaotic Advection for Enhanced Reagent Mixing
(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
(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
(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
(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
(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
(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
(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 ...
