AbstractRenewed exploration or development in historical mining districts, such as Cobalt, presents unique challenges for proponents and government regulators because of the cumulative nature of environmental impacts. To increase their capacity to carry out or review environmental assessments, this project will develop geoscience methods for distinguishing environmental effects of new mining activity from complex existing background conditions in affected watersheds. Specifically, the project will develop means of unraveling the history of accumulated polymetallic contamination from multiple sources over multiple periods. This information and new data from mine wastes and mine drainage will be synthesized in the first geoenvironmental model for Ag-Ni-Co-As vein type deposits. Project results will be disseminated to key end users in order to improve their capacity to carry out or review environmental assessments and to ensure that decision makers have a better understanding of the cumulative nature of environmental impacts for the sustainable development of natural resources.
Summary(Plain Language Summary, not published)
This is the fifth year for the project leaders of the Environmental Geoscience Program (EGP) from the Geological Survey of Canada (GSC) within Natural Resources Canada to present their annual scientific updates. Twelve power point presentations illustrate all the project status of all research going on within EGP. Subjects are connected to the following key words: Volcanoes, mercury, dredge disposal at sea, oil spills, diluted bitumen, oil sands, aquifer impacts, induced seismicity, geological storage of carbon, cobalt, climate change, Mackenzie River Basin, permafrost thaw, permafrost geochemistry, and cumulative effects.
