Biodegradation kinetics of individual and mixture non-steroidal anti-inflammatory drugs in an agricultural soil receiving alkaline treated biosolids
Land application of biosolids is one potential source of pharmaceuticals and personal care products (PPCPs) into agricultural soils. Degradation is an important natural attenuation pathway that affects the fate and transport ... -
Characterizaing sediment physical property variability for bench scale dewatering purposes
A field sampling program was undertaken to assess the variability of physical characteristics of contaminated sediments in a large (160 ha) effluent stabilization lagoon. The objective of this paper is to use this “field ... -
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 ... -
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 ... -
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 ... -
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 ... -
Quantifying hydraulic conductivity spatial variability for a cement-based solidification/stabilization (S/S) remediation project: a case study.
This paper presents statistical analyses of hydraulic conductivity data collected from an existing cement-based solidification/stabilization (S/S) system. The goal is to characterize the spatial variability of hydraulic ... -
Examining the Ultraviolet Optical Screening Tool as a Viable Means for Delineating a Contaminated Organic Sediment
Rapid and accurate delineation of contaminated sediments in marine environments is critical for the effective assessment of site risks and the development of appropriate remedial action plans. In this study, a new application ... -
Fate and transport of particle matter during geotube dewatering of a dioxin and furan (PCDD/F) contaminated sediment.
Geotextile tube dewatering is a pre-treatment method utilized in the remediation of high-water content materials (i.e. sediments and slurries). However, given the association some contaminants (e.g. dioxins and furans, ... -
Evaluating the movement of dissolved porewater species through a marine sediment 51 years after establishment of a pulp and paper effluent stabilization basin
Over 50 years ago, a marine estuary was converted to a wastewater stabilization basin for treatment of primarily pulp and paper effluent. As a result, the basin was immediately converted to a “freshwater” environment and ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ...
