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 Regional Aquifer Vulnerability and BMP Performance in an Agricultural Environment Using a Multi-Scale Data Integration Approach
(University of Waterloo, 2009-06-19)The increased use of both organic and synthetic fertilizers on agricultural land has lead to rising groundwater nitrate concentrations in some areas of southern Ontario. This has occurred at the Thornton Well Field in ... -
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 ... -
Hydraulic Tomography and Trichloroethene Dissolution in a Fractured Dolostone: Small Scale Laboratory Experiments
(University of Waterloo, 2011-12-21)In fractured geologic media, flow and contaminant transport are predominantly controlled by the fractures, their distribution and connectivity. The accurate characterization of fractured geologic medium, imaging of fracture ... -
Incorporating Advanced Surface and Subsurface Processes in Mesoscale Climate Models
(University of Waterloo, 2016-09-26)Regional anthropogenic climate change poses significant risks to the security of water resources for communities throughout the world. Current climate simulations seek to predict the risks to water resources by employing ... -
Natural Gradient Tracer Tests to Investigate the Fate and Migration of Oil Sands Process-Affected Water in the Wood Creek Sand Channel
(University of Waterloo, 2009-10-02)The In Situ Aquifer Test Facility (ISATF) has been established on Suncor Energy Inc’s (Suncor) oil sands mining lease north of Fort McMurray, Alberta to investigate the fate and transport of oil sands process-affected (PA) ... -
Passive In Situ Treatment of Acidic and Neutral Mine Drainage: Field and Laboratory Investigations
(University of Waterloo, 2009-12-16)Water quality degradation is the foremost environmental issue faced by the mining industry. Negative impacts on water quality are commonly associated with unmitigated drainage emanating from sulfide-bearing mine waste ... -
Persistence of Artificial Sweeteners, Phosphorus and Nitrogen in Three Septic System Plumes with Differing Redox Conditions
(University of Waterloo, 2018-10-31)Septic systems are widely used for on-site wastewater treatment throughout Canada, including at most of Ontario’s provincial parks. They are frequently located in unconfined aquifer systems that may also be used for water ... -
Simulating the Impact of Methane Gas Production from the Clearwater B Formation on the Regional Groundwater Flow System
(University of Waterloo, 2016-01-19)The production of natural gas from a saline aquifer will reduce the pressure regime in that aquifer to some degree. Simultaneously, this relief in pressure will causes gas to be exsolved out of the aqueous phase, which ... -
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 ...
