We're taking them very seriously. That's why, just since we were last together, we've added 175 additional wells that allow us to intercept this seepage and mitigate it. We have several hundred more wells planned over the winter season between now and the end of the year. It's all so that we can ensure that we are not impacting the environment any more than we already have and to mitigate that in the future.
I will acknowledge that on lease—not off lease, but on lease—we have some incidence of higher levels of arsenic, for example. Arsenic is naturally occurring in this area, but we've seen elevated levels. Part of our cleanup is to deal with this, but it has not gone off lease.
