Biodegradation kinetics of individual and mixture non-steroidal anti-inflammatory drugs in an agricultural soil receiving alkaline treated biosolids
Shu, W; Price, G; Jamieson, R; Lake, C.B (Elsevier, 2021)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 ... -
Development of a leaching procedure to asses the risk of uranium leaching due to construction and demolition waste
Letman, M.M.; Drage, J.; Ryan, A.M.; Lake, C.B.; Jamieson, R. (Elsevier, 2018)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 ... -
Examining freeze/thaw cycling and its impact on the hydrualic conductivity of cement-treated silty sand
Jamshidi, R.J.; Lake, C. B.; Barnes, C.L. (American Society of Civil Engineering, 2015)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 ... -
Examining metal migration through geotextiles during dewatering
Tackley, H.; Alimohammadi, M.; Lake, C.B. (Elsevier, 2020)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 ... -
Examining the Ultraviolet Optical Screening Tool as a Viable Means for Delineating a Contaminated Organic Sediment
Davidson, K.B.; Lake, C.B.; Sweet, B.; Spooner, I.S. (Elsevier, 2021)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.
Alimohammadi, M.; Lake, C.B. (Elsevier, 2022)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, ... -
Historical characterization and spatial distribution of organic contaminated sediment derived from kraft pulp mill effluent.
Hoffman, E.; Alimohammadi, M.; Lyons, J.; Davis, E.; Walker, T.R.; Lake, C.B. (Springer, 2019)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
Hayward, J.L.; Huang, Y.; Yost, C.K.; Truelstrup Hansen, L.; Lake, C.B.; Tong, A.; Jamieson, R. (Elsevier, 2019)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, ... -
Low impact development effects on aquifer recharge using coupled surface and groundwater models
Mooers, E.W.; Jamieson, R.C.; Hayward, J.; Drage, J.; Lake, C.B. (ASCE, 2018)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 ... -
Particle Size Effects on Breakage of ACT Aggregates Under Physical and Environmental Loadings
Choi, H.; Lake, C.B.; Hills, C.D. (American Society of Civil Engineers, 2020)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 ... -

Quantifying hydraulic conductivity spatial variability for a cement-based solidification/stabilization (S/S) remediation project: a case study.
Fenton, G.A.; Lake, C.B.; Liza, R.K. (Canadian Science Publishing, 2021)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 ... -
Spatiotemporal assessment (quarter century) of pulp mill metal(loid) contaminated sediment to inform remediation decisions
Hoffman, E.; Lyons, J.; Boxall, J.; Robertson, C.; Lake, C.B.; Walker, T.R. (Springer, 2017)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.
