I would say probably several years. The main concern is the regional groundwater flow patterns, how groundwater flows from the areas in which the in situ projects and the mining projects take place, and the impacts in those areas to which the groundwater moves.
I looked at a couple of the environmental impact statements that worried only about whether an in situ well would affect anybody else's groundwater--any farmer, or anybody right nearby. So it was a very local assessment that was undertaken. What the Alberta Research Council is saying is that we need to understand what's happening to the groundwater and its relationship to the surface water in this whole region.
