Conclusion

Land and Water Impacts of Oil Sands Production in Alberta

  • Technology is an important factor in reclamation of our land and water recources
  • We can make little improvements
  • 2 challenges we are working on improving: "The need to better quantify impacts and the other is to better address those that are not currently well managed.

How well prepared are we to manage these impacts?

  • Water markets have begun to emerge in Alberta due to water constraints
  • Water Management Framework

Thirsty for information of water Quality

  • The Gover't of Alberta has to monitor water quality more closely
  • Elevated levels of PACs found down stream
  • Wet Landscape Approach

Water and Land impacts are inherently local

It is necessary to consider local land and water availability and use due to the local nature of the impact

By: Sarah M. Jordaan

As oil sands production rises, so will water consumption

How Do these impacts compare to other transportation fuel options?

  • It is important to keep them in perspective in comparison with other transportation fuel options
  • Surface mines developed on peat lands are currently reclaimed to a mixture of uplands and wetlands.

2020:3.2 million of barrels a day

2025: 4.1 million barrels a day

2030: 4.8 million barrels a day

Surface Mining and In Situ Recovery Impacts

  • Surface mining results in conversion of large tracts of land
  • In Situ Recovery impacts fragment landscapes
  • Both of which result in ecological impacts

Summary

Surface Mining

  • Main points of this article are :
  • The growing concern about environmental Impacts of Oil Sands
  • Primary oil sands extraction technologies
  • Water quality and use

Oil Sands Extraction Technologies

Two Technologies are used: surface mining and In Situ recovery

Surface mining: "Best suited to widespeard layers of material such as coal, or near surface bodies such as uranium

In Situ Recovery: "Used for extracting deeper deposits"

In Situ Recover Process

After Tailings Pond

Increase of Oil Production and Impacts

  • grown from 0.7 to 1.6 million barrels per day since 2000 and is expected to double
  • 140 000 km of of oil sand Resource
  • Concerns about Tailing Ponds
