Redditor here. I have been to more than a few wells and I can tell you that the closest these companies get to having a scientist giving even one shit about what's going down into the well is, well, nobody. The only scientists on site are the geologists, whose only mission is to tell the drilling supervisor where they are and how much deeper they have to go before they stop and begin completion of the well. Period. Maybe one in ten wells actually get visited by the state/provincial or whatever government for some testing, but pretty much, it's a very cozy relationship. The drilling company only cares that the gas comes up and is captured for transport to market. Period. What happens after that? Who cares? It'll be ten years before anyone's water begins to show signs of contamination, right?
