Thank you to the witnesses.
Funnily enough, I was going to ask about groundwater, so maybe you're leading into that.
We had a witness here, Dr. Parker, who was talking about groundwater. I wasn't able to get too far into geothermal or some of the heat loads on groundwater and whether those are a risk, or fracking or mining, or risks for groundwater that are below the surface and that aren't being monitored. Could you talk about the need for quality management service for groundwater in anything that could happen in our report here? Could you be fairly brief, if that's possible?
