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+) ... -
Assessing Stratigraphic Controls on the Secondary Detrital Footprint from Buried Mineralization and Alteration at the Highland Valley Copper Mine, British Columbia
(University of Waterloo, 2020-01-24)Mineral exploration is progressively shifting to deeper targets, including those buried under thick unconsolidated sediments. It is thus becoming increasingly important to understand the sedimentary successions of the ... -
Diavik Waste Rock Project: Geochemical and mineralogical investigations of waste-rock weathering
(University of Waterloo, 2012-12-05)The oxidation of sulfide minerals in mine waste rock has the potential to generate acidity and contribute sulfate, metals and other trace constituents to drainage. The rate and extent to which this process occurs are ... -
Evaluating Controls on Arsenic Geochemistry at the Long Lake Gold Mine in Sudbury, ON
(University of Waterloo, 2020-06-01)The release of As from old mine sites can persist long after cessation of mining activities. This project combines field and laboratory research components at the Long Lake Gold Mine site, near Sudbury, Ontario. The mine ... -
Fingerprinting Quaternary Subglacial Processes on Hall Peninsula, Baffin Island, using Multiproxy Data
(University of Waterloo, 2014-01-23)It is important to study subglacial environments in northern Canada for many reasons, such as to develop a more comprehensive understanding of glacial landscape development and to aid in mineral exploration. The purpose ... -
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 ... -
Hydrological and Geochemical Implications of Aquifer Depressurization on Expansive Peatland Systems in the Hudson/James Bay Lowlands
(University of Waterloo, 2016-04-08)The ecological integrity of the peatlands of the Hudson/James Bay Lowlands (HJBL) is vulnerable to hydrological changes associated with climate change and resource development. Dewatering of an open-pit mine (the DeBeers ... -
Influence of Freeze-Thaw Dynamics and Spatial Contributions on Geochemical Loading from a Low Sulfide Waste-Rock Pile
(University of Waterloo, 2014-06-18)An experimental waste-rock pile (50m x 60m x 15m, 0.053 wt. % S) was constructed at the Diavik Diamond Mine, in the Northwest Territories, Canada to evaluate the generation of acid-rock drainage and the seasonal and annual ... -
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 ... -
Investigation of Gas Transport Rates Through a Covered Waste Rock Pile and Synchrotron Studies on the Sulfide Oxidation Reaction
(University of Waterloo, 2017-01-19)This thesis presents a field based investigation into gas transport mechanisms and rates through a waste-rock pile with a low permeable cover, and a synchrotron based study into intermediate sulfidic species that are ... -
Methylmercury Production in Riverbank Sediments of the South River, Virginia (USA) and Assessment of Biochar as a Mercury Treatment Option
(University of Waterloo, 2014-01-24)Mercury (Hg) is a toxic element which bioaccumulates in the food chain when methylated and poses a health risk to the human population mainly through fish consumption. It is released into the environment through both ... -
Paleozoic transpressional tectonics in the Beishan orogenic collage, Northwest China: Evolution of the Hongliuhe suture zone
(University of Waterloo, 2016-01-21)The Beishan orogenic collage is a southern, central subset of the Central Asian Orogenic Belt, in Northwest China. It is an accretionary orogen that was active during the early Paleozoic, transitioning to convergent ... -
Sequential Extraction of Trace Metals as Geochemical Indicators of Land Use Near Ancient Metallurgical Sites in Faynan, Jordan
(University of Waterloo, 2023-01-23)Civilizations are tied to soils through a reliance on agriculture. In the Faynan Valley, southern Jordan, both the individuals who tend to the soils and the soils themselves have evolved through a series of environmental ... -
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. ...
