Advances in Modeling, Sampling, and Assessing the Anthropogenic Contamination Potential of Fractured Bedrock Aquifers
Kozuskanich, John C. (2011-03-01)Groundwater is an important resource that is relied on by approximately half of the world’s population for drinking water supply. Source water protection efforts rely on an understanding of flow and contaminant transport ... -
Anthropogenic Impacts on Sensitive Fractured Bedrock Aquifers
Levison, Jana (2009-10-26)Groundwater is an important water resource that must be protected from potential contamination due to anthropogenic activities such as industrial production and agriculture. It is necessary to understand the presence, ... -
An Aquifer-Well Coupled Model: a Refined Implementation of Wellbore Boundary Conditions in Three-Dimensional, Heterogeneous Formations
Cyr, D. Matthew (2008-01-15)This paper presents modifications to two widely used numerical groundwater flow models in an effort to improve upon the interaction between a well of finite length and conductivity with the surrounding formation. The first ... -
A comparison between solute transport in a discrete fracture and in a fracture network using a novel method for tracer detection
Moore, Brian Hector Mathias (2008-08-27)Characterization of field-scale transport in bedrock aquifers is necessary due to the preponderance of groundwater contamination in these settings, and the increasing attention paid to these sites by regulatory bodies. ... -
The effect of biostimulation on geochemical and microbiological conditions in an isolated dolostone fracture
Knight, Lesley (2008-09-19)A biostimulation field trial was conducted to determine the effect of nutrient addition on microbial populations in a fractured rock environment. The ultimate goal of this research is to induce bioclogging in rock fractures ... -
The Effect of Glaciation on Hydraulic Head and Solute Transport in Sedimentary Host Rock Potentially Used for Nuclear Waste Disposal
Khader, Omar (2014-05-30)A Deep Geologic Repository is proposed for a site on the eastern margin of the Michigan Basin at a depth of 680 metres in the Cobourg Formation. A study of the paleo-hydrogeolgical conditions for the area was conducted ... -
The Effect of Thermally and Chemically Enhanced Biostimulation on the Hydraulic Properties of a Discrete Fracture Network in a Bedrock Aquifer
Smith, Reid T. (2010-12-06)The impact of thermally and chemically enhanced biostimulation of indigenous bacteria in a fractured rock aquifer and the resulting changes in hydraulic properties of the discrete fracture network were investigated at the ... -
The Effects of In-Situ Stimulation of Natural Biofilm on Groundwater Flow and Back Diffusion in a Fractured Rock Aquifer
Bayona, Luis (2009-08-17)Remediation of DNAPL contaminated sites in fractured rock has proven to be very difficult. No current technology can be used to remediate such sites in a timely and economic manner due to the inherent heterogeneity of ... -
Groundwater recharge, flow and discharge in a large crystalline watershed
Gleeson, Thomas (2009-07-14)The objective of this thesis is to constrain the fundamental hydrogeological processes of a large crystalline fractured rock watershed in the Canadian Shield. The fundamental hydrogeological processes of groundwater recharge, ... -
Heated Biofilm Growth in a Planar Fracture for Reduction of Hydraulic Aperture
Grell, Stephanie Louise (2011-08-10)The objective of this study was to examine the effect of heat on the growth of a biofilm in a parallel glass plate fracture table. Groundwater was collected from a limestone aquifer and amended with a nutrient mixture ... -
Identifying downhole fracture characteristics using in-situ fluorescence monitoring : the results and interpretation of a large-scale radially divergent tracer experiment conducted in a dolomite aquifer
Melaney, Michael (2008-07-16)In several field studies it was concluded that highly transmissive features transmit the majority of solute mass in horizontally-fractured bedrock aquifers. The purpose of this investigation is to develop a new technique ... -
Investigation of the Effects of Biofouling on the Hydraulic Properties of Wells in Fractured Bedrock Aquifers
Cooke, Brenda Elizabeth (2007-12-18)The objective of this study is to improve the understanding of the effect of biofilm growth and biofouling on well performance in a fractured rock aquifer. The study was conducted by investigating biofouling in several ... -
Laboratory Studies of Biobarrier Technology in Fractured Rock
Mann, Vanessa (2012-11-27)Experiments exploring transport and bio-containment of contaminants in fractured rock were completed using fractured-limestone samples obtained in eastern Ontario, Canada. Three single-fracture samples, a fracture-intersection ... -
The presence and transport of human enteric viruses in fractured bedrock aquifers
Trimper, Shawn (2010-11-11)Both onsite septic disposal systems and private drinking water wells are commonly utilized in rural areas of Canada. The coexistence of septic systems and drinking water wells has the potential to greatly impact the quality ... -
Processes Governing Rapid Recharge Events in a Shallow Fractured Rock Aquifer Having Minimal Overburden Cover
