I"ve read that when you are gonna be in a production unit. The driller will get your water tested.  Will this water be tested by a water conditioning company, like say Culligan, or will it be done by the landman, or a private co.? Will it be by mail,or will they come to your door?  Dont think it would work if done by the O&G co. cause most people would'nt trust that. Interested to see how it was done in your neck of the woods.
