The presence of sulfur oxidation intermediates (SOIs; e.g. S2O32-, SO3 -, S0, etc.) in  
mining wastewater is a significant industry-wide concern because of the potential for  
acidification and toxicity of receiving water bodies, resistance to treatment and the  
current lack of monitoring tools. Bacterially catalyzed transformation of sulfur species  
under real world conditions remains poorly constrained, limiting the development of  
biologically integrated indicators. As part of a larger project investigating the microbial  
links to mine water S chemistry for the water system of Ni, Cu mines in Northern  
Ontario, the objective of this investigation is to characterize the in situ S geochemistry of  
Glencore’s Oxidation Reservoir (Onaping, ON) over seasonal, operational and annual  
scales. As the Reservoir receives diverse water inputs from three mining companies,  
waste rock, tailings lines and multiple watersheds, these are also being assessed over  
seasonal scales to establish their contributions to observed Reservoir geochemistry.
