That's a good question.
While we hydraulically fracture the well, we produce the water back into a secure containment. That water is then recirculated and pumped back into that same reservoir in a slightly different location, an 800-metre-deep reservoir. So we dispose of the water that comes back from our hydraulic fracturing operation back down into that same-source reservoir. It's a closed-loop system and it's recycled back into that saline aquifer, right back into the source. Again, the integrity of the pipelines and the well bore is engineer-designed, but also well regulated to protect the fresh water.
