If that water is mixed and interlaced with chemicals, some of which we all admit we wouldn't want to drink if we didn't have to, the public's concern would be whether those chemicals then return back to the water supply. The volumes are quite extraordinary. I mean, 12 million to 32 million litres per well is a lot of water. If there's some number of tonnes of chemicals going down, some of them carcinogenic, and 50% of that, we assume, doesn't come back up, it's now in an aquifer supply that people are going to rely on for their drinking water and for basic living.
