Evaluating Controls on Arsenic Geochemistry at the Long Lake Gold Mine in Sudbury, ON
(University of Waterloo, 2020-06-01)The release of As from old mine sites can persist long after cessation of mining activities. This project combines field and laboratory research components at the Long Lake Gold Mine site, near Sudbury, Ontario. The mine ... -
Removal of Arsenic and Metals from Mine-impacted Groundwater Using Organic Carbon and Zero-valent Iron in Passive Remediation Systems
(University of Waterloo, 2020-09-21)Arsenic (As) is a wide-spread contaminant, often encountered in drainage associated with Au mining. The oxidation state controls the mobility and toxicity of As in water. Passive remediation is a potential management ... -
Speciation dynamics of oxyanion contaminants (As, Sb, Cr) in argillaceous suspensions during oxic-anoxic cycles
(Elsevier, 2018-04-01)Argillaceous geological formations are considered promising repositories for waste containing inorganic contaminants. However, the sequestration capacity of an argillaceous natural barrier may change as a result of dynamic ...
