 You know, that's a little more challenging in terms of how we need to take that sample. If you're using well water, say, like you would be in southwest or western Kansas, that's a little easier process. But just, you know, just those two things do tend to go hand in hand. And we often forget that water can be a significant source of mineral and mineral antagonisms that can cause us some production problems as well. So it's always those two things are always go hand in hand. It's really important to kind of have to take one with the other.
