Assessment of permeable reactive barriers for sulphate reduction at the former Steep Rock Iron Mine site, Atikokan, Ontario
(2012-11-10)This study assessed if a permeable reactive barrier (PRB) could be used to reduce sulphate and metal concentrations in Hogarth pit lake, a sulphate-toxic (up to 2,000 mg/L) pit lake at the former Steep Rock iron mine in ... -
Bioremediation of contaminated soils from mine sites using native plants in Northwestern Ontario
(2016)Practical and scientific importance can be found in this research topic since the results directly apply to remediation of industrial and mined lands in the boreal forest region. Plants suitable for phytostabilization of ... -
The Decline of a Northern Lake Superior marsh : a study of the cause and effect
(2009)This study quantified the loss of vegetation in Mission Marsh located within the city limits of Thunder Bay on the northern shore of Lake Superior, suggested the most likely cause of this vegetation loss, and examined in ... -
Environmental Considerations for Wet Mining Peatlands in Northwestern Ontario
(2012-11-10)Signi cant changes in water quality were detected using a Before-After-Control-Impact (BACI) experimental design. Porewater showed increases in pH, alkalinity, conductivity (including Ca, Mg, K, Na), some metals (Sr, Ba, ... -
Fish biomonitoring in an industrial environment : the Toxicity Early Warning System (TEWS)
(2009)Industrial, agricultural and municipal effluent discharge into receiving waters continues to be a significant environmental problem. Currently, industrial effluent quality is assessed using chemical assays or by evaluating ... -
Geochemical and toxicological investigation of the Hogarth and Caland Pit Lakes, former Steep Rock Iron Mine site
(2012-11-10)The closure of the Steep Rock Iron Mines near Atikokan, Ontario, Canada in the late 1970's left behind an area of severe environmental concern. The subsequent flooding of the pit mines resulted in the formation of two ... -
The Influence of wetlands and watershed geology on lake chemistry of five remote lakes in Northwestern Ontario
(2012-11-10)In chapter 1 of this study the relationship between spatial, chemical, and biological factors and their influence on mercury concentration s in walleye were examined. Water, sediment, and fish tissue samples were collected ... -
Isolation of arsenite-oxidizing bacteria with plant growth promoting characteristics to enhance phytoremediation of arsenic
(2021)A common strategy for remediation of arsenic is bacterial remediation by oxidation of As(III) to the less toxic As(V). Another widely accepted technique for arsenic remediation is phytoremediation however in highly ... -
Lowbush blueberries in Northwestern Ontario as a commercial crop option in post-harvest peatlands
(2009-10-15)Wild blueberries (Vaccinium angustifolium Ait.) were investigated as a possible reclamation tool for post harvest peatlands in Northwestern Ontario, by genetic fingerprinting using microsatellite markers, an examination ... -
Northern wild rice (Zizania palustris L.) as a phytoremediation species in eutrophic wetlands - investigation of root-sediment interactions
(2014-01-22)The causes of anthropogenic eutrophication in water bodies are multi-faceted and multigenerational, presenting an ever increasing need for effective and sustainable solutions.Phytoremediation presents a cost-effective ... -
Predicting mixing trends in mine-receiving waters using water quality modeling
(2016)Complete mixing of the water column of lakes is important to ensure that nutrients and dissolved oxygen are replenished and equalized throughout the lake. This ensures that organisms within the lake at all trophic levels ... -
Utilization of alternative testing methods in the evaluation of pulp and paper mill effluent toxicity
(2020)Pulp mills are required to perform routine regulatory testing to ensure the effluent they release from their water treatment plants is not harmful to humans and the environment. The key components within the effluent ... -
Utilization of hydrodynamic modeling in predicting water quality and Brook Trout habitat: reclamation of a mine impacted Boreal Shield Lake
(2020)Mining operations in Ontario are subject to regulatory limits on effluent release into surrounding waterbodies designed to preserve aquatic life. However, said guidelines may not always be enough to prevent damage to the ... -
Wild rice (Zizania palustris L.) re-establishment through mechanical removal of invasive cattails (Typha angustifolia L.)
(2019)Re-establishment of wild rice following the removal of the invasive cattail, Typha angustifolia, was examined in a traditional and culturally important stand of wild rice belonging to the Seine River First Nation on Rainy ...
