(University of Waterloo, 2007-09-18)Sites where 2-chlorobutadiene-1,3 (chloroprene) and 2,3-dichlorobutadiene-1,3 (DCBD) are synthesized for use in chlorobutyl rubber have the potential to release a mixture of at least five chlorinated butenes and butadienes ... -
Delineating Base Flow Contribution Areas for Streams: A Model Comparison
(University of Waterloo, 2012-06-21)This study extends the methodology for the delineation of capture zones to base flow contribution areas for stream reaches under the assumption of constant average annual base flow in the stream. The methodology is applied ... -
Demonstration of Nitrate-Enhanced In Situ Bioremediation at a Petroleum Hydrocarbon Contaminated Site
(University of Waterloo, 2011-10-28)Alternative strategies involving in situ remediation technologies have been developed to assist with property clean up, however, cost-effectiveness and discrepancies in success rates and timeliness continue. The objective ... -
The Design Of An Out-Diffusion Experiment And The Use Of Geochemical Analyses For The Purpose Of Matrix Pore Fluid Extraction And Characterization: A Case Study For Radioactive Waste Disposal
(University of Waterloo, 2008-04-30)Deep crystalline rock formations of low permeability have been identified as a possible geological medium for high-level radioactive waste disposal. In order for the safe disposal of radioactive waste, a site characterization ... -
A detailed hydrologic evaluation of tile-drained macroporous soils: A field and modelling study
(University of Waterloo, 2011-03-07)The underlying objective of this research is to improve the overall understanding of how spatial and temporal variability in macroporosity and soil hydraulic properties in the shallow subsurface influence the long term ... -
Developing and refining the use of water isotope tracer in hydrology and paleohydrology
(University of Waterloo, 2008-08-27)This thesis investigates stable isotope signals (i.e. δ18O and δ2H) in various information carriers such as lake water and lacustrine sediments, aiming to develop and refine the use of isotope tracers in hydrology and ... -
Developing the Hydrologic Model of the Laurel Creek Watershed Including the Water Infrastructure
(University of Waterloo, 2016-01-22)Continued growth of the Canadian economy has led to an increased population, which resulted in the progressive urbanization of Canada’s watersheds. Additionally, as infrastructure ages, an increasing percentage of drinking ... -
Developing Virtual Field Experiences to Promote Student Learning and Bridge Knowledge Gaps between the Classroom and the Field
(University of Waterloo, 2021-05-01)In 2020, a specific type of Virtual Reality (VR), Virtual Field Experiences (VFE), was identified as a proof-of-concept for positively contributing to student learning by the University of Waterloo's Department of Earth ... -
Development of a New Technique to Study the Kinetics of Hydroxyl Radical Uptake on Micron-Sized Organic Aerosols
(University of Waterloo, 2010-04-28)The importance of the hydroxyl radical (OH) to tropospheric chemistry is well known. The radicals’ ability to react with most atmospheric trace gases allows it to act as the main removal mechanism for these gases. Due to ... -
Development of a Parallel Computational Framework to Solve Flow and Transport in Integrated Surface-Subsurface Hydrologic Systems
(University of Waterloo, 2012-04-11)HydroGeoSphere (HGS) is a 3D control-volume finite element hydrologic model describing fully-integrated surface-subsurface water flow and solute and thermal energy transport. Because the model solves tightly-coupled ... -

(University of Waterloo, 2018-05-22)The application of Mo isotope compositions in petroleum systems is a new field of research. In this study, elemental concentrations and Mo isotope compositions were measured on crude oils, asphaltenes separated from the ... -
The Developmental History of a Cupriferous Swamp in Southeastern New Brunswick, Canada
(University of Waterloo, 2010-09-30)Cupriferous swamps are characterized by high concentrations of copper in the soil and water. The Aboushagan swamp, situated 8km northwest of Sackville, New Brunswick is a unique metalliferous wetland where copper is ... -
A Device for Measuring Groundwater Velocity in the Capillary Fringe
(University of Waterloo, 2007-05-22)Groundwater flow in the capillary fringe is rarely measured during hydrogeological studies because of the difficulties associated with investigating this region. Previous research using a point velocity probe (PVP) to ... -
