We actually have done extensive testing. What I was describing in my opening statement was that as we looked at all of the wells that we have drilled—all of the access to fluids—and analyzed them, the furthest we have seen any impact is 1.3 kilometres off our lease.
However, we have looked beyond that. In fact, we've taken samples all the way at the river—both at the banks and in the river—and confirmed that there is no continuation of that plume.
The whole reason we have this monitoring system is so that we can continue to validate that it is not going any farther. Now, with the pumping and interception system that we've expanded, our objective is to effectively move that plume back onto our lease and eliminate it from spreading any further.
