Long Term Dynamics And Potential Remediation Of Fine Textured Soils And Ground Water Contaminated With Chlorinated Organic Compounds And Salts
DownloadFall 2019
Contamination of land, water, and air is a widespread concern often associated with anthropogenic activities. Remediation of contaminated sites is necessary to minimize negative impacts on human health and the environment and allow for safe, productive use of land. Although contaminated sites...

One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

Exploring how soil fungi can be used to restore native trees on reclaimed substrates containing petroleum hydrocarbons
DownloadSpring 2023
As part of reclaiming landscapes mined for bitumen, ecosystems must be revegetated to restore self-sustaining ecosystems in the boreal forest of western Canada. Current reclamation practices can involve the construction of large landforms, sometimes from overburden containing up to 8%...

Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

Canadian Writers, McClelland & Stewart, and the Paperback Book: Remediation, Publishing, and Cultural Context
DownloadSpring 2014
This dissertation analyzes the relationship between literature and new media through an investigation of the book in a Canadian context and draws on book history and new media studies. To better understand the relationship between print and digital forms of publishing, I look backwards to a...

Treatment of Oil Sands Process-affected Water (OSPW) Using Integrated Fixed-film Activated Sludge (IFAS) Reactors
DownloadFall 2016
The oil sands process-affected water (OSPW) generated from bitumen extraction of oil sands, is currently stored in tailings ponds due to its toxicity to the aquatic organisms. The primary toxic constituents of OSPW are a complex mixture of alicyclic and aliphatic compounds containing carboxyl...

This study examines the effects of Pseudomonas aeruginosa (PAO1) biofilm, with a concentration of cells similar to that reported for saturated aquifers, on the transport of poly(acrylic acid) stabilized nanoscale zero valent iron (pnZVI) in 14 cm long, saturated, laboratory packed columns, with...
