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 ... -
Development of a toxicity early warning system (TEW)
(2006)Biomonitoring is a practice that has over time developed into a remarkably accurate form of detecting toxicity in the environment. The Toxicity Early Warning system (TEW) is a Real-Time Biomonitoring system developed to ... -
Effectiveness of self-restoration for two small mine impacted shield lakes
(2003)Cleaver Lake and Horneblende Lake in the Whitesand Watershed were studied for the impact of mining and milling activities. No release of zinc, copper, iron, or manganese was detected in aerated sediment samples and there ... -
Effects of water depth increases on the production and growth of wild rice, Zinzania aquatica L.
(1987)Wild rice, grown in plastic buckets suspended from specially designed rafts, was subjected to increases in water depth during the submerged-leaf, first floating-leaf, second floating-leaf, and the first aerial-leaf ... -
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 ... -
Growth of wild rice, Zizania aquatica L., in flocculent sediments
(1988)The objectives of this research were to classify sediments from wild rice lakes, and to examine, in detail, one type of sediment that is not suitable for commercial production of wild rice. Based on physical and chemical ... -
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 ... -
Limnology and remediation of two proximal pit lakes in Northwestern Ontario
(2005)Two adjacent pit lakes, Caland and Hogarth, were formed after the closure and subsequent flooding of the Steep Rock Iron Mines near Atikokan, Ontario, Canada. They were examined to predict flooding patterns, outflow ... -
Limnology of two proximal pit lakes after twenty years of intense flooding
(2001)Two adjacent pit-lakes, Caland and Hogarth, formed after the flooding of open pit iron mines near Atikokan, Ontario, Canada, were examined for their water quality relationships and potential to support aquaculture. ... -
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 ... -
Prediction of a modern gold mine's contaminant dispersion and deposition in a river mixing zone
(2000)Study site: Placer Dome Canada's Musselwhite Mine near Pickle Lake Ontario. -
Role of aquatic macrophytes in trophic status of Northwestern Ontario lakes
(1993)This research focusses on the development, refinement, and assessment of regional trophic status models for lakes of northwestern Ontario. Two companion papers describe the application of image analysis of aerial photographs ...
