Autor: David Robert Lee, Carlos Duque, Donald O. Rosenberry
Publikováno v: Rosenberry, D O, Duque, C & Lee, D R 2020, ' History and evolution of seepage meters for quantifying flow between groundwater and surface water : Part 1 – Freshwater settings ', Earth-Science Reviews, vol. 204, 103167 . https://doi.org/10.1016/j.earscirev.2020.103167
More than 75 years after its introduction, the seepage meter remains the only device for directly quantifying exchange across the sediment-water interface between groundwater and surface water. This device, first presented in the literature in the 19

Effects of 90Sr on Tree Swallow Nestlings Near Groundwater Contaminant Plumes
Autor: Amy Festarini, Danielle Beaton, Lee Bellan, Andrew Valente, Hui Qun Chen, Marilyne Stuart, Isabelle Gosselin, Jennifer Haughton, David Robert Lee
Publikováno v: Health physics. 117(3)
Discharge of groundwater contaminant plumes has created elevated concentrations of Sr in some aquatic sediments at Chalk River Laboratories. Tree swallows (Tachycenita bicolor) feed and supply their nestlings almost exclusively with airborne insects

Reactive transport modeling of 90Sr sorption in reactive sandpacks
Autor: David Robert Lee, Sung-Wook Jeen, Jun Yin, K. Ulrich Mayer
Publikováno v: Journal of Hazardous Materials. 280:685-695
Strontium-90 (90Sr) is one of the most problematic radioactive contaminants in groundwater at nuclear sites. Although 90Sr is retarded relative to groundwater flow, it is sufficiently mobile and long-lived to require treatment in many hydrogeological

Longevity Estimates for a Permeable Reactive Barrier System Remediating a 90Sr Plume
Autor: David Robert Lee, Jutta Hoppe, David W. Blowes, Sung-Wook Jeen
Publikováno v: Uranium-Past and Future Challenges ISBN: 9783319110585
A permeable reactive barrier system, known as the Wall and Curtain, was installed at the Chalk River Laboratories, Chalk River, Ontario, in 1998, to intercept a 90Sr plume. The system employs clinoptilolite, a zeolite, as a reactive material which ad

Gardner, Gerald T. Ankley, David M. Gardiner, Michael D. Shelby, Rick B. Levey, Michael Lannoo, James G. Burkhart, Robert C. Hale, Carol U. Meteyer
Publikováno v: Environmental Health Perspectives
The recent increase in the incidence of deformities among natural frog populations has raised concern about the state of the environment and the possible impact of unidentified causative agents on the health of wildlife and human populations. An open

Modeling the Groundwater Flow of a 90Sr Plume Through a Permeable Reactive Barrier Installed at the Chalk River Laboratories, Chalk River, Ontario, Canada
Autor: Jeff Bain, Sung-Wook Jeen, David Robert Lee, Dale Hartwig, David W. Blowes, Jutta Hoppe
Publikováno v: The New Uranium Mining Boom ISBN: 9783642221217
In 1998, a passive remediation system known as the wall and curtain was installed at the Chalk River Laboratories in Ontario, Canada, to prevent a 90Sr plume present in the lower part of a 12 m thick aquifer from discharging into a nearby swamp. To p

Method for locating sediment anomalies in lakebeds that can be caused by groundwater flow
Autor: David Robert Lee
Publikováno v: Journal of Hydrology. 79:187-193
A device was designed to be dragged along lakebeds for locating anomalies in sediment temperature or chemistry. The drag was a density-balanced probe containing temperature transducers and an electrical conductivity cell. The drag was used successful
