We have some of these still operating in the local area, nowhere near as many as before the drop in natural gas prices four or five years ago. I suspect from the length of time this one has been on same site (three months) that it is conducting multiple fracking holes.
Fracking is controversial, no one knows what chemicals are exactly being used and long term consequences are largely unknown. The local community is divided, however running a business in town I keep my opinions to myself.
