The point I was trying to make, in terms of the technical requirements around the completion of the wells, is illustrated in the slide that shows the cement and the steel casing that is put in place. It is intended to separate the producing zones from those upper shallow water aquifer zones. So there is engineering applied to this. There is a regulatory environment that requires us to adhere to those practices to ensure that we do provide that measure of protection.
In addition to that, as we talked about the MAC process, one of the recommendations the department of the environment has mandated now is that we do water well testing. We test the wells in proximity to the coal-bed methane wells we drill, to confirm the condition of that water prior to drilling those wells, to understand whether or not methane is present. If it is present, the presumption is that it's naturally occurring, and then following up with that, if there's any change in that water well after the fact, we know we've got something to look at.
