ASSESSMENT OF TWO THERMALLY TREATED DRILL MUD WASTES FOR LANDFILL CONTAINMENT APPLICATIONS
Offshore oil and gas drilling operations generate significant amounts of drill mud waste, some of which is transported onshore for subsequent thermal treatment (i.e. via thermal remediation). This treatment process results ... -
Characterizing Porosity and Diffusive Properties of Monolithic Cement-Based Solidified/Stabilized Materials
This paper presents the application of a single reservoir diffusion test to determine both the effective porosity of a soil-cement matrix and the diffusivity of tritium through saturated, monolithic, cement solidified/stabilized ... -
Evaluating Impact Resonance Testing as a Tool for Predicting Hydraulic Conductivity and Strength Changes in Cement-Stabilized Soils
In this paper the impact resonance (IR) test method is used as a nondestructive tool to examine the curing progression, freeze/thaw (f/t) resistance, and healing potential of cement-stabilized soils. Resonant frequency ... -
Statistical Sample Size for Quality Control Programs of Cement-Based Solidification/Stabilization
Sampling requirements for the quality control (QC) of cement-based solidification/stabilization (S/S) construction cells do not currently specify the sample size considering the accuracy of the estimated effective hydraulic ... -
Examining freeze/thaw cycling and its impact on the hydrualic conductivity of cement-treated silty sand
Cement-based solidification/stabilization (s/s) is a remediation technology that has been widely used for treatment of a range of contaminants. Currently there is limited published data on changes in hydraulic performance ... -
Hydraulic and strength performance of three cement-stabilized soils subjected to cycles of freezing and thawing
A total of 108 specimens were prepared to examine the hydraulic performance and strength performance of nine different cement-stabilized soils under unexposed and freeze–thaw exposed conditions. Specimens from each mix ... -
Manufactured aggregate from cement kiln dust
This paper presents the results of a laboratory study that evaluated the geotechnical and geoenvironmental properties of a manufactured aggregate derived from cement kiln dust (CKD). The aggregate manufacturing process ... -
THE EFFECT OF FREEZE/THAW CYCLES ON THE PERFORMANCE AND MICROSTRUCTURE OF CEMENT-TREATED SOILS
In this paper, the performance and structural changes in cement-treated soils under influence of freeze/thaw (f/t) exposure are investigated. Specimens from plastic and compacted soil-cement mix designs were exposed to ... -
Geotextile biofiltration of primary treated municipal wastewater under simulated artic summer conditions.
Wastewater stabilization ponds (WSPs) are common for wastewater treatment in remote Canadian Arctic communities. In this paper, two geotextiles of different mass/unit areas are examined as a potential biofiltration upgrade ... -
An Analytical Approach to Assess Quality Control Sample Sizes of Cement-Based Solidification/Stabilization
This paper presents an analytical approach to selecting the sample size required to achieve acceptable quality control in a cement-based solidification/stabilization construction cell program intended for the treatment/containment ... -
Spatiotemporal assessment (quarter century) of pulp mill metal(loid) contaminated sediment to inform remediation decisions
A bleached kraft pulp mill in Nova Scotia has discharged effluent wastewater into Boat Harbour, a former tidal estuary within Pictou Landing First Nation since 1967. Fifty years of effluent discharge into Boat Harbour has ... -
Diffusion and Sorption of VOCs Through Soil-Cement Materials
This paper presents a laboratory study that assesses the diffusive and sorptive parameters of three volatile organic compounds benzene, ethylbenzene, and trichloroethylene) though cured, monolithic, soil-cement materials. ... -
Using a geotextile with flocculated filter backwash water and its impact on aluminium concentrations
The use of geotextiles (i.e. geotextile tubes) in wastewater treatment applications is ever increasing. This paper examines the potential of using a geotextile to improve upon the treatment of aluminium present in a filter ... -
Low impact development effects on aquifer recharge using coupled surface and groundwater models
Low impact development (LID) is promoted as a sustainable management practice for stormwater in urbanized catchments. While the positive effects of LID features on surface water hydrology and water quality have been ... -
Development of a leaching procedure to asses the risk of uranium leaching due to construction and demolition waste
Naturally-occurring uranium can be found at elevated concentrations in groundwater throughout the world, with the potential to cause kidney damage in chronically exposed individuals. Empirical evidence shows that uranium ... -
Historical characterization and spatial distribution of organic contaminated sediment derived from kraft pulp mill effluent.
Organic sediment contaminants [polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/Fs), and polycyclic aromatic hydrocarbons (PAHs)] were assessed using secondary monitoring data from a former tidal ... -
Lateral sand filters are effective for removal of antibiotic resistance genes from domestic wastewater
The ability of lateral flow sand filters, used as on-site wastewater treatment systems (OWTS), to remove antibiotic resistance genes (ARGs), antibiotic resistant bacteria (ARB), and other relevant genetic markers (HF183, ... -
The effect of different dewatering techniques on resulting effluent particle size.
A paucity of literature has compared geotextile dewatering methods to more conventional dewatering methods (i.e. centrifuge, sedimentation) in the context of how geotextile dewatering performs at reducing particulate matter ... -
Examining metal migration through geotextiles during dewatering
This paper presents a study conducted to assess the influence that a filter cake deposited on the surface of the geotextile has on the mobility of three metals (Cu, Pb, Zn) during filtration of a contaminated sediment. Two ... -
Particle size effects on breakage of ACT aggregates under physical and environmental loadings
Aggregates manufactured from fine-grained thermal waste residues using accelerated carbonation technology (ACT) represent a potential sustainable alternative to natural aggregates. However, for these manufactured products ...
