Rem this much I can tell you for certain; Across the road from my property a well was dug...the reclaimation ponds were dug (2 huge holes) the entire 200yds circle was stripped of all topsoil...the well came up empty!. The well was capped off an within a few months the water pumped out of the holes and they were filled in...the topsoil replaced and reseeded...now there is a round clearing in the woods about 200 yds across with lush green grass growing in it...except for that an the access road pushed into the area you'd never know there was anything done to the area.
Just what happens to all the water they pumped out of those holes I'm not certain.
