"We just didn’t anticipate the fractured flow in the subsurface, which you probably would find with shale anywhere. The fractured flow medium is probably what caused concerns because you didn’t have one path flow that you could map. You can’t model fractured flow medium. No way to know where it’s going to go. But even so with proper containment methods you don’t have an issue."
