Well, yes and no. That's an excellent question, but it's also a bit tough to answer.
As Dr. Rivera said, it takes maybe 10 years to recharge this aquifer system. We're interested in the dynamics, but it's very hard to get a handle on the dynamics from a one-year study. We can certainly accelerate some parts of it and we can collect lots of different types of data, but there still are uncertainties that we just can't deal with. We have to take a longer time to know how these things—
