The basis for the wells is some extensive work we had done with subject matter experts on the geology, the hydrogeology, to understand the source of this additional aquifer, the source of additional groundwater, that was contributing to this seepage pathway to the surface.
We continue to engage those consultants, and that's the basis for the additional monitoring wells, the additional pumping wells and the additional trenches, all of which are intended to now address any new-found learnings around the hydrogeology.
