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 ... -
Characterization and Modeling of Selected Antiandrogens and Pharmaceuticals in Highly Impacted Reaches of Grand River Watershed in Southern Ontario
(University of Waterloo, 2013-10-01)Endocrine disruption and high occurrences of intersex have been observed in wild fish associated with wastewater treatment plant (WWTP) effluents in the urbanized reaches of the Grand River watershed located in southern ... -
The Hydrochemical Fate and Transport of Treated Domestic Wastewater Contaminants During a Wastewater Polishing Experiment in a Sub-Arctic Ladder Fen Peatland
(University of Waterloo, 2016-09-27)Protecting northern aquatic ecosystems is critical to ensuring the sustained use of these environments; however, with increasing industrial and residential development pressures in this region the safe and effective treatment ... -
Mercury Transformation and Release from Contaminated Soil Following Perturbations in Solution Chemistry and Application of Polysulfide
(University of Waterloo, 2018-04-09)Mercury (Hg) is a contaminant of concern due to the very high toxicity and bioaccumulating nature of organic Hg and the persistent leaching of Hg to water bodies from contaminated soils and sediments. The deleterious ... -
Modeling the Transportation of Select Trace Organic Contaminants from Source to Ecosystem in the Grand River
(University of Waterloo, 2021-06-02)Trace organic contaminants (TOrC) have been observed in waters downstream of wastewater treatment plants (WWTP) in the Grand River in southern Ontario, Canada. These contaminants have been correlated with adverse impacts ... -
Parameter Estimation and Uncertainty Analysis of Contaminant First Arrival Times at Household Drinking Water Wells
(University of Waterloo, 2007-01-25)Exposure assessment, which is an investigation of the extent of human exposure to a specific contaminant, must include estimates of the duration and frequency of exposure. For a groundwater system, the duration of exposure ... -
Saturated and vadose zone fate and transport of a continuously released tracer in a sub-arctic bog peatland
(University of Waterloo, 2017-02-22)In Ontario’s James Bay Lowland, sub-arctic bog and fen peatlands make up 90% of the landscape. Increasing resource extraction operations in this area pose a risk of contaminant release into these systems, both intentional ... -
Uncertainty Analysis and the Identification of the Contaminant Transport and Source Parameters for a Computationally Intensive Groundwater Simulation
(University of Waterloo, 2009-05-15)Transport parameter estimation and contaminant source identification are critical steps in the development of a physically based groundwater contaminant transport model. Due to the irreversibility of the dispersion process, ...
