That is a good question. One thing to recall about the in situ oil sands industry is that the resource is spread over quite a large geographical distance. We have operations up in the Peace River area, south of the Fort McMurray area, as well as in the Cold Lake-Beaver River basin. It's probably over a 500 kilometre distance.
In the Cold Lake-Beaver River basin, which is quite a mature in situ oil sands area, there are wells that are currently operating, as well as monitoring wells to track that sustainability. As industry expands into these areas, saline water is evaluated at each project for use within the project, and those sustainability questions are asked as part of the EIA process and expansion.
