Ammonium Attenuation and Nitrogen Dynamics in Groundwater Impacted By a Poultry Manure Lagoon
(University of Waterloo, 2011-06-21)Fertilizer application and manure use practice in agriculture has become one of the most common sources of dissolved nitrogen species to both ground and surface waters. Nitrogen, released as nitrate (NO3-), ammonium (NH4+) ... -
Establishing Metrics to Quantify the Vulnerability of Municipal Supply Wells to Contaminants from Surface Water Sources
(University of Waterloo, 2014-08-22)This study was completed in conjunction with the Regional Municipality of Waterloo and the Southern Ontario Water Consortium, with assistance from the Canadian Water Network and Grand River Conservation Area with the main ... -
Evaluating Vadose Zone Moisture Dynamics using Ground-Penetrating Radar
(University of Waterloo, 2012-02-27)Near-surface sediments in the vadose zone play a fundamental role in the hydrologic system. The shallow vadose zone can act as a buffer to delay or attenuate surface contaminants before they reach the water table. It also ... -
Examining Hydrogeological Processes in Freezing Soils using Remote Geophysical and Numerical Techniques
(University of Waterloo, 2019-02-11)The work presented in this thesis aimed to demonstrate the use of remote geophysical methods and numerical modelling to address questions related to hydrogeological processes in freezing soils. Two different study areas ... -
Geochemical Characterization of Groundwaters, Surface Waters and Water-Rock Interaction in an Area of Continuous Permafrost Adjacent to the Greenland Ice Sheet, Kangerlussuaq, Southwest Greenland
(University of Waterloo, 2016-01-21)Continental scale glaciations, such as those that covered much of Canada and Northern Europe during the last glacial maximum (26,000 to 19,000 y BP), can be expected to cause large disturbances to both the surficial and ... -
High-Resolution Geophysical Characterization of an Ethanol Release into an Existing Gasoline-Impacted Zone
(University of Waterloo, 2012-04-09)This study aims to evaluate the ability of high-frequency (450 and 900 MHz) ground-penetrating radar (GPR) to monitor the effects of an ethanol release over an existing gasoline-contaminated zone. In September 2009, 184L ... -
Integrated Solid Phase, Aqueous Phase and Numerical Investigation of Plume Geochemistry at an Oil Sand Mining Facility
(University of Waterloo, 2006)A plume of process-affected groundwater was identified in a shallow sand aquifer adjacent to a tailings impoundment at Syncrude Canada Ltd. Quantitative and qualitative Naphthenic Acid (NA) analyses were performed on ... -
Towards Quantifying Groundwater Resources of the Paloluoma Buried Bedrock Valley in Western Finland with Groundwater Modelling
(University of Waterloo, 2022-05-03)Groundwater provides about 60 percent of drinking water in Finland. In western Finland, drinking water for the town of Kurikka (pop. ~21 700) comes from glaciofluvial aquifers confined underneath thick glaciomarine aquitards ... -
The Use of Temperature and Environmental Isotopes as Tools to Characterize Groundwater Discharge to the Grand River, Ontario, Canada
(University of Waterloo, 2013-01-25)The Grand River Watershed, in southern Ontario, is home to approximately 900,000 people and one of the fastest growing regions in Canada; specifically, in the urban areas of Guelph, Cambridge, Kitchener, and Waterloo. ...
