You're not aware of any cases where contamination has happened. It's remarkable.
One of the questions I have is about trying to understand the geology of these aquifers in British Columbia and whether they're contiguous or self-contained or migratory. If an aquifer gets contaminated--which it does, in terms of the injection of this water and the release of water and the gases that come up--does it have the ability to migrate over to another aquifer? Can it affect the drinking water supply further down the line in the seam? Is it your contention that that's not possible?
