Advanced Data Analysis Of In-Situ Bioremediation Site Data Using Dimensionality Reduction Techniques
Chlorinated solvents are one of the most prevalent groundwater contaminants in North America. Many of these contaminants are very difficult to clean up due to their physical properties and can pollute drinking water aquifers ... -
Anthropogenic Impacts on Sensitive Fractured Bedrock Aquifers
(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, ... -
A comparison between solute transport in a discrete fracture and in a fracture network using a novel method for tracer detection
(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. ... -
Effects of Bubble-Facilitated VOC Transport From LNAPL Smear Zones on Vapor Intrusion
Light non-aqueous phase liquid (LNAPL) sources can pose a significant threat to indoor air through vapour intrusion (VI). Most conceptual and numerical models of VI assume that the transport of volatile organic compounds ... -
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
(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
(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 ... -
A laboratory study of the effectiveness of thermal remediation on creosote impacted soil
Groundwater can be impacted by many types of contaminants, some of which are difficult to remediate, such as dense non-aqueous phase liquids (DNAPLs). DNAPLs can exist for long periods of time in the subsurface and may ... -
A LABORATORY STUDY ON THE EFFECTS OF DISSOLVED GAS EXSOLUTION ON THE PERFORMANCE OF IN-SITU THERMAL TREATMENT TECHNOLOGIES
In-situ thermal treatment (ISTT) technologies are a set of remediation methods for treating chlorinated volatile organic compound (CVOC) dense non-aqueous liquid (DNAPL) source zones by increasing the temperature of the ... -
A Modeling Study of Large-Scale Solute Transport in Fractured Carbonate Rock
Fractures influence aqueous contaminant transport by allowing for rapid migration over long distances through complex pathways and through diffusion into the adjacent rock matrix. While there have been many studies examining ... -
Numerical Modeling of Thermal Enhancement of In Situ Chemical Oxidation (ISCO) and Enhanced In Situ Bioremediation (EISB)
(2014-02-11)A numerical model was utilized to assess the effects of elevated temperature on the application of in situ chemical oxidation (ISCO) and enhanced in situ bioremediation (EISB) for the subsurface remediation of trichloroethene ... -
Processes Governing Rapid Recharge Events in a Shallow Fractured Rock Aquifer Having Minimal Overburden Cover
(2013-10-16)The goal of this work is to investigate the influence of overburden cover on controlling recharge to a bedrock aquifer, specifically focusing on rapid recharge events. Rapid recharge events have been observed in a fractured ... -
Stray Gas Migration in Shallow Groundwater: Gas Dynamics, Mass Transfer, and Environmental Expression
The objective of this research was to systematically investigate the dynamics of flowing subsurface gases, leading to understanding of mass loading of stray gas in unconsolidated sands, then couple this knowledge to ...
