Characterizing Chromium Isotope Fractionation During Reduction of Cr(VI): Batch and Column Experiments
(University of Waterloo, 2012-02-22)Chromium (VI) is a pervasive groundwater contaminant that poses a considerable threat to human health. Remediation techniques have focused on the reduction of the highly mobile Cr(VI) to the sparingly soluble, and less ... -
Effectiveness of Organic Carbon Cover Systems on Sulfide-rich Tailings
(University of Waterloo, 2021-09-27)Acid mine drainage (AMD) occurs when sulfide minerals oxidize; generating low pH water and the release of dissolved metals. This phenomena is of primary concern in the mining industry, where the future loading of dissolved ... -
Perturbations to nutrient and carbon cycles by river damming
(University of Waterloo, 2017-06-30)The damming of rivers represents one of the most far-reaching human modifications to the flows of water and associated matter from land to sea. Globally there are over 70 000 large dams whose reservoirs store more than ... -
Some Aspects of Arsenic and Antimony Geochemistry in High Temperature Granitic Melt – Aqueous Fluid System and in Low Temperature Permeable Reactive Barrier – Groundwater System
(University of Waterloo, 2008-02-11)Arsenic and antimony are important trace elements in magmatic-hydrothermal systems, geothermal systems and epithermal deposits, but their partitioning behavior between melt and aqueous fluid is not well understood. The ...
