Laboratory and Modelling Study Evaluating Thermal Remediation of Tetrachloroethene and Multi-Component NAPL Impacted Soil
(2013-10-02)In Situ Thermal Treatment (ISTT) is a candidate remediation technology for dense non-aqueous phase liquids (DNAPLs). However, the relationships between gas production, gas flow, and contaminant mass removal during ISTT are ... -
A Laboratory Examination of Down-slope Bentonite Erosion in Geosynthetic Clay Liners
(2014-05-01)Geosynthetic Clay Liners (GCLs) are commonly paired with a geomembrane and used as part of a composite liner system for landfill barriers. Under some circumstances, leaving a composite geomembrane/geosynthetic clay liner ... -
Laboratory Investigation of Diluted Bitumen Trapping and Dissolution in Gravel
(2016-08-26)The Canadian economy is largely dependent on the distribution of large volumes of oil to domestic and international markets by a long network of pipelines. Unfortunately, accidents occur, and oil can leak or spill from ... -
Laboratory Studies of Biobarrier Technology in Fractured Rock
(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 ... -
Laboratory study evaluating electrical resistance heating of pooled trichloroethylene
(2009-03-18)A laboratory scale study was conducted to evaluate the thermal remediation of trichloroethylene (TCE) in a saturated groundwater system using electrical resistance heating (ERH). Two experiments were conducted using a ... -
Laboratory study evaluating thermal remediation of tetrachloroethylene impacted soil
(2008-01-04)A laboratory study was conducted to assess the relationship between degree of volatile organic compound (VOC) mass removal from soil and heating duration, initial dense non-aqueous phase liquid (DNAPL) saturation, and grain ... -
Laboratory study of geosynthetic clay liner shrinkage when subjected to wet/dry cycles
(2009-06-02)Geosynthetic Clay Liners (or GCLs) are often used in conjunction with a geomembrane for landfills and heap-leach pads, where their function is to minimize leakage that may occur through holes in the geomembrane. GCLs are ... -
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 ... -
Landfill Leachate Toxicity to Oncorhynchus mykiss (Rainbow Trout) at the Merrick Landfill
(2016-07-04)At the Merrick Landfill, located outside of North Bay (Ontario, CA), an investigation into the potential for an environmental impact to the Little Sturgeon River as a result of landfill leachate discharge was undertaken ... -
Large-Scale Horizontal Coherent Structures in a Deep Open Channel Flow: an Experimental Study
(2014-10-30)This work is a study of the size, dynamics and morphological consequences of large-scale horizontal coherent structures (HCS's) in a deep open-channel flow. The study has the following three objectives: 1- to assert the ... -
Leakage Phenomena of Tailings Overlying a 1 cm Diameter Circular Geomembrane defect
Leakage phenomena for two types of tailings overlying a 1 cm diameter geomembrane defect were studied. The first type of tailings was a Silty Sand. Various underliners (DF15/DB85=5.6 to 13.5) not meeting typical retention ... -
Limit States Testing of a Buried Deep-Corrugated Large-Span Box Culvert
(2009-01-15)Results are reported from full-scale testing of a buried, deep-corrugated, large-span box culvert with a 2.4 m rise and 10.0 m span under controlled laboratory conditions. A total of twenty-one experiments were conducted ... -
Long Term Monitoring of a Retrogressive Landslide in Sensitive Clay Using Low Altitude Digital Photogrammetry
(2015-04-30)Champlain Sea Clay, also known as Leda Clay, is a glaciomarine clay that was deposited between 12,500 and 10,000 BP within the limits of the Champlain Sea transgression during the retreat of the Laurentide ice sheet. ... -
Long-Term Performance of HDPE Geomembranes as Landfill Liners
(2009-02-02)High density polyethylene (HDPE) geomembranes are normally used as part of a composite liner for waste containment facilities such as municipal solid waste (MSW) landfills and heap leach pads. Field conditions, which include ... -
Longevity of HDPE Geomembranes in Geoenvironmental Applications
(2014-02-28)With sufficient time, a high density polyethylene geomembrane will degrade and lose its engineering properties until ruptures signal the end of its service-life. This thesis examines the longevity of nine different ... -
Low and high temperature performance of near surface mounted FRP strengthened concrete slabs
(2008-04-24)Near surface mounted (NSM) FRP reinforcement has recently emerged as a promising alternative technology for strengthening concrete structures in both flexure and shear, as opposed to externally bonded FRP strengthening ... -
