Document Summary
Mixture of sand, clay water and bitumen. ~20% of canada"s supply oil production has increased since 1967: projected 3300000 barrels/d (2025, 482 000 barrels/d (1995) Mineable bitumen surface mines rivers create steep banks layers of exposed bitumen can see liquid oil draining down to stream stream is layered in gravels of bitumen oil sands too deep to mind. Bitumen and condensed water are stored for transport to an upgrader facility. Habitat destruction and reclamation: wetlands, boreal forest. Water use (1. 5 to 4 volumes of water/volume of oil) Chemical emissions: water quality, air quality, tailings ponds. Government of alberta: human health and environment not at risk, natural erosion is the source of metals and polycyclic aromatic compounds (pac) What methods are key to answering these questions: need appropriate study designs. Background" or reference conditions are not well defined because of natural sources of bitumen: need appropriate tools. Flow and concentrations of contaminants in the athabasca.
